oil not getting to my rockers?????

[baked bean coloured dolly]

i took off the sump today and checked the pump it all seemed ok the gauze was clear and the clearances were ok i took the rocker bar off and blew through it and it was clear all the rokers were clear too i attached a pipe to the hole that goes from the head to the block and blew i heard bubbles at the bottom end it seemed quite hard to blow through to the point that when i stopped i was dizzy i put it all back together and started the car when i took the rocker cover off there was no oil coming out of the rockers. i took the screw out of the rocker bar that holds it all together and there was no oil i know the head is clear cos i done the head gasket and blew it through...........please help.

Only thing i can suggest is oil pump drive is sheared and once i heard of a pickup in the sump to low and was fouling on the bottom of the sump<br>
Cheers<br>

pulled the whole pump out drive ok and pump pick up was no where near the bottom so still im stumped but i did see written on the oil filter 21/1/01 - 29431 the actual mileage is 30842 so i guess thats about 1400 miles in 5 years maybe the filter needs changing...............?

It's only supposed to come out rediculosuly slowly isn't it? And I've read something about the rocker mechanism sliding and covering the feed hole I think. I don't know, my car doesn't have rockers <!--EZCODE EMOTICON START :D --><img src=http://www.ezboard.com/images/emoticons/happy.gif ALT=":D"><!--EZCODE EMOTICON END-->

there is no oil whatsoever coming up out of the rockers and the feed holes are on the bottom of the rocker pipe (is that right) and they dont seem to line up with the rockers. The car is nearly ready for the mot all bar this problem i dont think i can drive the misses mini for much longer before i take a hammer to it, it just wont stop breaking down poxy spi engines why did they change them.

If you are a TDC member you may have been reading the series of articles I have written titled Running the ‘Old’ car’s. Below is an extract from the draft report for the next edition of DM, which you may find interesting. <br>
<br>
Next I decided to have a look at the rocker shaft, as the rockers were very noisy compared to my other cars. On getting the shaft out I found that it looked as if the front five rockers had not been getting sufficient oil as both the inside of these rocker arms and the corresponding areas of the rocker shaft were badly scoured. My explanation as to why the rear three were O.K is the fact that these would have got some oil poured over them each time the engine oil was topped up which is quite frequently as this engine does burn more oil than the other cars in the old fleet. On investigating the lack of oil to the rocker shaft I found that when I took the bolt out from the rear, near side of the cylinder head, I could not push a small screw drives into the oil way very far before it came to a stop and it needed a considerable amount of force to clear the blockage. Hence I believe that oil was not getting or at least the full flow was not getting as far as the rocker pedestal / rocker shaft. Next I decided to see what the oil flow was like when I ran the engine with the bolt out. I was most surprised to discover that even after the oil pressure light had gone out it took a considerable time for any oil to come out of the oil way bolt hole and even then it lacked any pressure. This worried me so I decided to run the same test on my spare engine. The result was just the same so I am hoping that I do not have two engines with the same problem. I did think about removing the oil pressure gauges from one of my running cars to measure the oil pressure but decided against it in the end. Some times you just do not want to know, as it would have involved more work if it was low. It was only at this stage that I thought about the crud that I had obviously shifted with my screwdriver in the oil way. It was now a bit late but I decided that I would take the rocker pedestal off once again to see if I could remove any of the crud before it moved further along the oil way and caused a further blockage. I did find some but I am concerned that I may not have got the lot.<br>

My 1500 had exactly the same problem. I have cured it by thoroughly cleaning out the oilway through the head that supplies the rocker shaft.<br>
<br>
To do this I had the luxuary of removing the head which meant I could clean out the 3 different parts to the oilway using drill bits. The oli comes out a lot better now!<br>

Question for BDN 12V.<br>
<br>
Have you run the engine with the oilway bolt at the rear of the head out as I am curious to know what your flow rate and pressure is like at that point.<br>
<br>
On the two engine that I have looked at as I stated earlier there was very little pressure and the flow rate was very small. However I could see oil coming out around the rockers when I replaced the bolt.<br>

unlike your engines i have no oil at all coming up to the rockers even with the screw taken out of the shaft i have completely cleaned the head the pedastals the rocker shafts and the rockers with little drill bits boy did that take a while as i said in my first post i could just about blow through the oilway in the block until my cheeks hurt and i became dizzy as i dont have an airline what could i fire down there to clear the oilway out any suggestions? I will beat the beast thats for sure it might just take a while

You can get an engine flushing oil but I do not know how well it works when you have a blockage. <br>
<br>
Are you aware that the bolt beside the petrol pump (rear of pump) also goes into or blanks the oil way in the engine block. It may pay to take it out and have a poke around in it with a piece of wire or pipe cleaner. I have used this as point for connecting in a pressure gauge on two of my cars. At this point I have say 70 psi when cold and about 50psi @3000rpm when hot so I was surprised to find no real pressure at the oilway blanking bolt hole, at the rear of the head. I am now wondering if I have two engines with the oilways partially blocked. I must have a look at my other engines to see what pressue / oil flow they have.<br>

The best way to go may be to fit a rocker oil feed kit that various suppliers sell as this would solve the problem once and for all time. <br>
<br>
It is a external pipe that feeds oil from the blanking plug hole in the main engine bloc to the cylinder head blanking plug. <br>
<br>
Rimmers part number RR1340 @ a cost of £33.93 but I am assuming the item that Moss bros identify for the 1500 Spitfire engine will also fit part number TT1226 @ a cost of £20.95<br>
<br>
I have not yet had time to check my other engines I will report back in due course.<br>

I'm not sure what pressure I got - didn't test that as I went straight to the external feed! Didn't want to risk it!<br>
