I was thinking about having the head skimmed but I just couldn't throw any more money at it.

One think the machinist told me was if I had the stud holes counterbored it would stop the head from swelling around the holes, as the angled studs push against the head. You can just make out the swelling in the bottom pic. Luckily on mine it is very slight.

That's caused by wrong tightening sequence.

Hi Mart what about that guy giving away a dolly front door in Taunton.
Is that of any use to you?

Thanks for the heads-up Jon. I would have it for spare but have nothing to pick it up in.

Spent most of today checking/adjusting valve clearances. I still haven't finished. :roll:

Finished the valve clearances first thing, just one shim needed, which I can pop in at a later date as it's an exhaust shim.

I thought I'd better check the bearings whilst I had the engine out. Mains were ok but the big ends needed replacing...

Finding TDC...(that's Top Dead Centre not Triumph Dolomite Club :lol: )

Image

Image


Once TDC is set on no.1 cylinder I bolt a pointer to the front cover then stick my timing template on the crank pulley to align with the pointer at 0 degs....


Image

Image


Then I rotated the crank to line up with the 106 deg. mark. This is the installation figure for my cam, Newman cams TRID-292-408 (TT10106 equivelent)...


Image

Image


Next thing to do was to set the inlet valves on no. 1 cylinder to their fully open position. Because I've set this cam up before I was able to use the marks I'd put on previously, so no need to use the dial gauge...


Image

Image

Image


Then I fitted all the timing gear, making sure the run of chain on the right (as you view it) between the crank & camshaft was taught. There was a small amount of play but this was taken up using the vernier cam pulley.

Lovely work. :D
May I just ask why everyone deems it so important to make sure the long bit of chain is taught? My chain is taught most of the way round but has a slack point. I fitted a new tensioner which didn't sort it, maybe I should've adjusted the slipper?
Does it just mean that my cam timing will be slightly retarded at the slack point?

Dan, when you set up the timing chain all the slackness is taken out with the curved guide (on the left). the tensioner is only there to take up any slack as the chain stretches over time.

I love reading your threads mart and the stuff you do. They make me feel so inadequate :D

seriously, they contain a wealth of information and how-to, thanks and good work on the car.

You won't want to scratch it when its finished.
