That's passenger side Dave, to get over the irregular shape of the bulkhead, there's an aluminium plate mounted by 3x 1/4" bolts to the bulkhead like bolthead, bulkhead, nut, plate, nut in that order so it stands just proud by a nut's thickness. one nut holds the top of the ECU too, another does duty as the earthing point and the 3rd secures the ign live booster relay to the board. I've now added the other 3 relays in a block screwed up to the underside of the screen frame reinforcement and looks nice and tidy. Still have to make the loom for ECL and leccy windows but the relayed feeds are there now to work from, this can be added anytime! I'll take a better pic when I have daylight to help!

I've had another productive couple of days, the fuel feed AND return is now complete, i've wired up the fuel pump and (something i've been meaning to do for ages) replaced the ratty tatty Scotchlock infested original 78 rear section loom with a real nice condition 1980 one that i've kept for this car (late loom includes foglight wiring) So now I can dismantle it in the middle by the B post to add the wiring for the indicator repeaters which i've already laboriously threaded up through the B posts to the lamp fitting area.

A couple of parts came in the post on Saturday so i've added them in and now have an air cleaner and a lovely bit of bling ally piping to plumb it with!

Lots of lovely cold air will get in there!

Finally got around to something i've had in my head for about a year and been putting off almost as long, fitting the throttle potentiometer and modifying the pedal!

So first I cut the top 1" off the Omega's pedal which includes a ball for the linkage, then opened up the cable slot in an original pedal and welded the blade section piece of the Omega pedal into the slot. So far, so good. Replaced the original pedal and it clears where it needs to, RESULT! Then I offered up the potentiometer on it's Omega fitting bracket, marked the position of the bolt holes, drilled the bulkhead to suit and bolted it into place. Now the clever bit, hinged the (non length adjustable) ball socket rod round and clipped it over the ball on the pedal which is in EXACTLY the correct place! I love it when a plan comes together! Tests confirm that I have full throttle travel and the pedal reaches it's "kickdown" position (identified by a slight ridge in the operation) about a carpets thickness off the floor! I've left the original Sprint auto bulkhead stiffener in position, just in case of stress on the weak bulkhead, but it may not be needed, the new "fly by wire" throttle is smooth and light in operation and i'm a happy bunny! Still better to have it and not need it than vice versa! For a finishing touch, I found and fitted a blanking grommet to the hole previously occupied by the throttle cable. This also acts as a silent pedal "up" stop!

Image

I've just quickly tried again, but I don't think this pic explains much more than the last one! The screen on my phone is half dead, so I don't know what the pics are like till they are on the computer!

Image

Lastly a quick shot of the rats nest of heater, servo, fuel and trans cooler pipes that lives down at the o/s/r corner of the engine! Fortunately most of this lot will be obscured once the servo and master cylinder are in place!

OK, so 3 or 4 weeks ago, I got to the stage of trying for a first startup. I'd rechecked and made good a couple of mistakes and got a download of the Omega wiring diagram which is a joy to use as it's sort of interactive, you click on a part of the diagram and it automatically takes you to the next diagram of what you want to visit. Trying to do this from a paper diagram is nearly impossible, I think they must have been designed to be used digitally from the start.

Comforted by the knowledge that I haven't made any glaring errors, I connected the battery and commenced checking all the circuits for function, which I had with one or two easily fixed exceptions.

However, I had, of necessity, incorporated the electronic immobiliser from the Omega into my loom. This is activated by a chip in the key. I had carefully saved the chipped key, intending to use the chip and key housing with a modified Dolomite key in the ignition switch. This would have been a bit of a PITA to achieve and a bigger one was getting the bulky immobiliser housing into the Triumph column shroud. I'd not really found a solution, but for now, the idea was just to tape the Vauxhall key into the immobiliser housing and go from there.

This is where it all went pear shaped, The ignition comes on fine, engine management light illuminates, as well as the Transmission self test light. A touch on the starter button and the engine cranks over satisfactorily and after a few turns the oil light goes out. But there's no trace of any willingness to fire!

A couple of quick checks confirm there is no switching power from the ECU to the main engine relay or the fuel pump relay. A power feed INTO the fuel pump relay confirms the fuel pump is operational, leaving it on for 20 secs confirms fuel at the rail, through the pressure reg and into the return pipe by highlighting a leak in the return pipe onto the floor! 5 minute break while I tighten a jubilee clip on the return pipe I missed the first time!

Plugging in the diagnostic results in a "no communication" message, so my conclusion is that the immobiliser chip reciever is not recieving the signal from the chip, ie the reciever and the chip have fallen out of synch. This is apparently possible, especially since neither have had power though them for 7 years. I ve checked all the feeds INTO the ECU (there are 5, in total, both ignition and permanent live) and all are correct and supplying power as they should.

Now the immobiliser is a complex little bit of kit with it's own circuit board of electronics, 2 feeds and a chip of its own, so it's NOT a case of crossing wires and hoping. What's more, Google is no longer my friend, an exhaustive search on "How do I bypass the immobiliser on my 2001 Omega B?" says either "Dunno mate" or "I know but I won't tell you, in case someone uses the knowledge to nick MY Omega!"

After a lot of head scratching and swearing and an even more exhaustive search, I have found a company in Stoke, who, for a price that is only NEARLY exorbitant, will replace the chip and board in my immobiliser with one of their own devising which completely bypasses the immobiliser circuitry, but still powers the ECU and it's link to the diagnostic plug in the original manner. I should have this item back in my possession on Monday, so hopefully should have the car running soon. Unless of course there is another problem as well! Wish me luck!

PS this company undertake immobiliser repairs on many other makes and an also do key chip resynchs. If this works, i'll have no hesitation in recommending them to anyone who needs such a service on their modern! Apparently, Vauxhall, in common with many other manufacturers these days, won't even OFFER the resynch process on any car more than 10 years old. The excuse is obsolete software, but I suspect it's more designed in obsolescence. I have myself condemned a number of Renaults (and a couple of others) to scrap for insoluble immobiliser problems, knowing this guy exists may help more survive this!

IT LIVES!!!!!

I got the immobiliser back from the guys at Automotive Electronics in Stoke on Wednesday last week and after removing the engine management loom earlier, I have made a couple more corrections and simplifications of the circuitry.

So today I reinstalled it in the car (10 mins as it's "plug and play" by design) reconnected the battery, switched on the ignition and after uttering a brief prayer, hit the "start" button, to be INSTANTLY rewarded with all 4 cylinders singing sweetly, if a little loudly on the open downpipe. Oil light instantly extinguished, rev counter reading nicely and voltmeter climbing happily towards 14v. No signs of oil or water underneath and the idle settling happily as the cold start relinquishes its hold, I hesitantly hit the (fly by wire) throttle and it revs smoothly. Now REALLY pushing the boat out, I select reverse and it engages with a slight clunk and the wheels show it going backwards, drop through neutral to drive and again everything works normally. A bit of a graunch back into park but i've no brakes plumbed in yet to stop the driveline turning. I switch it off, nonchalantly I think, pause and take a breath!

You don't need much imagination to visualize the size of my grin at this point! I'm still buzzing as i write this 4 hours later!

THIS is why I do this, this golden moment, when all the planning, scheming, dreaming, obstacle suppression, cold, damp, brainstorming and sheer hard graft all comes together in a mechanical symphony that would make a more demonstrative man than I am dance for the sheer joy of it! Even the first drive out can't match this, finishing from here is nuts bolts and paint. This moment is MY Triumph (in more ways than one)

10 months from tomorrow, the 2020 RBRR will be setting off from Knebworth and I am now confident that the Dolomega will be amongst the starters. I can't begin to tell you all how chuffed I am about this!

Steve

PS, the immobiliser bypass cost me just shy of £180! Right now I count it as money well spent and thank the gods of PPI refunds for financing it!

It’s like a Constant uphill battle.
One step forward and mostly three back.

After a certain point it all comes together.
Nice to see another Dolomite back on the road.

Great colour choice
Not that I’m biased in anyway. 👍

Very well done Steve, it's going to be one hell of a car. 8)

Spent Sunday afternoon finishing off the Dolomega's dash panel. New electronic speedo fitted and wired in, plus the connections made for the rear foglight switch and a hole drilled for the front fog warning light and that wired up as well. All the extra bits means i've had to add a 4th plug to the set to keep it "plug and play".

As I now have 2x5 pin plugs (as well as a 7 and a 9) I thought it prudent to reverse the male/female for the new plug so I don't get them mixed up when fitting.

I really HAVE been watching too much Binky, their ethos of overdoing everything has rubbed off on me!

However, i'm eternally aware that sometime, somewhere, SOMEONE is gonna have to work on this thing besides me. And i'd rather they blessed my name than cursed me for a useless bodger who couldn't be ars*d to do it right the first time!

Astute observers will notice the Voltage stabiliser is now on the back of the rev counter, rather than under the bonnet. This is part of my expanded fusebox design where a single fuse now powers ALL the instruments (but only the instruments) Those that are stabilised are powered through the VS and those that aren't, like the tachometer, speedo and voltmeter, are powered off the input side of the VS.

I got 2 pics downloaded then Postimage went down! i'll add the plug pic later!

Steve

PS Saturday saw me enrolled in the 2020 Club Triumph Round Britain Reliability Run which departs Knebworth for all points North, South, East and West on October 2nd next year. So now I really AM under the cosh!

And these are the plugs!

Image

I'm lucky enough (or have sufficient foresight) to have acquired a number of old wiring looms. Besides giving me a good supply of wire in all the correct colours, they also donate these Lucas/Rists plugs. Whilst you CAN still buy the plugs and sockets as well as the pins that go in them, the plastic plugs are stupidly expensive, a single 5 pin like this can cost around £15 by the time VAT and carriage are considered - and that is without the pins! So I have become very adept at getting the pins out of the plugs!

So here is a request, if you break a car, save the looms! Even if they are mouse chewed, badly bodged or partially burned, I'll still take them!

Steve

Hi Steve, I noticed that there are a couple of people knocking Lucas RISTS connectors out on ebay at the moment at slightly more reasonable money. (Just in case your recycled stock runs out)

Not much has happened since my last report, with Christmas and my enforced retirement and moving out of the workshop has kept me too busy to work on the Dolomega.

Aware of my RBRR deadline though, I spent a few hours this weekend crossing off some of the tasks on the whiteboard, though not as much as i'd hoped, I have changed out the front tie bar bushes for standard shore poly ones and mostly refitted the antiroll bar, also with new rubber bushes and clamping brackets from Fitchetts in its revised position below the tie bars and supported under the subframe forward extension. I was hoping to have completed this and swapped out the rear upper tie bar bushes, also with stock shore poly, by the end of this weekend. Life, however, had other ideas and I spent the best part of 3 hours this afternoon drilling out the bolt between the tie bar and the o/s track control arm which snapped off when I tried to loosen it! Ho Hum!

It was pretty cold too, our back garden doesn't see a lot of sun this time of year and the frost on the grass when I went out at 1pm was still there when I came in at 5.30!

Steve

Few more jobs crossed off the list last weekend, i've been doing bits and pieces since my last post, but this is the first time i've put some solid work in!

Firstly i've changed the cam cover seal for a new one, there was an oil leak at the n/s/r corner that I had noted way back in 2012 when I was driving the donor Omega around. Whilst I was about it, I carefully sanded the Vauxhall logo and "ecotec" script off the plug cover and substituted a Triumph badge. I know it won't fool anyone but it looks kinda neat!

Image

Having had the engine running satisfactorily, I now proceeded to strip the engine bay back to the flitches to clean off the ziebart and paint the engine bay in the appropriate Vermillion. The original plan called for pulling the engine and trans back out and spraying the engine bay in body colour, the time constaints mean it's staying put and i'll brush paint the bay with "Vermillion" Smoothrite, mixed from red and yellow factors stuff. I've done this before and achieved a good match to several Triumph factory colours, Signal red, Midnight blue, Damson, Conifer green etc.

As I mentioned on Murdo's resto thread, petrol, rag and hard work is great for getting Ziebart off and the stuff really does protect the car, before and after shots of the cleaned flitches!



Next I changed out the timing belt and water pump along with all the tensioners and jockey wheels. I had no history on the donor car, which had covered just 70k from new and it's a 70k belt interval. So I was expecting to find it all original, but when I took the cover off, it was apparent that everything had been recently replaced, the belt still had legible writing on it, the water pump bore a QH sticker and was still shiny and all the timing marks were clearly highlighted with Tippex. However, "recently" is relative, the engine had been lying around unstarted since 2013, so even though all the parts are probably still good, it's not worth the risk, so I changed them all again with genuine Gates bits. No pics of this as you lot will have no interest in how to change an Omega timing belt!

Image

Image

Image

Finally i've gotten around to fitting the n/s headlamp support panel that has been lying around for years.

Image

Now I can do the final fit on my NOS outer front panel nad eyebrow and the good used n/s/f wing that came off the Carledo when the GRP panels went on in 2012/13! Recycling rules (well sometimes!)

Onwards and upwards!

Steve

Nice bit of work Steve, love the Triumph badge on the engine :lol: It will make people take a second look and maybe a head scratch 8)
