Pump may not be bolted to block properly, or the pickup pipe is leaking or broken. 9.85 @ 145mph

Pump may not be bolted to block properly... Correct, or rather the pump cannot bolt to the block properly. I’ve got a bit more investigation to do, but it appears that the drive “blade” on the pump is bottoming out inside the drive slot in the end of the cam. Certainly, without a gasket in place you can feel that the pump rocks on the drive blade. All the oil was disappearing through the cam bearing and back into the block, hence we could not see what was happening without splitting the engine/ gearbox. It was obviously not bad enough to affect pressure when running, but enough to drain the pump when not running. This original pump is a standard 1275 oil pump. I have a new Turbo pump which we have fitted and that seats properly. Now there is no evidence of oil leaking back through the cam bearing. Very rough measuring gives ~0.5mm difference in the length of the oil pump drive blades, from mating surface of the oil pump to the top of the drive blade, the standard 1275 pump being the longer. So now we are going to take a look and see if all is well with the cam fitment. On 26th Apr, 2015 BENROSS said:

But…. I think this maybe the ultimate reason for no oil getting up to the pump:
What can it be??? Closer inspection:
Paper… Lots of mushed up paper. At this point all I can surmise is that either the cam has moved (??) Or that this is how it was when originally built. I guess this explains the reason why I have had so many issues with having to repeatedly prime the oil pump. As stated originally, most of the engines running life was without driving it, so my guess would be that the paper was “whole” up until the point I did the test runs, so although I had a bitch of a job priming, once it was running, there was no issue with drawing the oil from the sump. Then after the test runs, the paper got mulched up and blocked the pickup filter. Maybe. Anyhow, gearbox now to be stripped to get it cleaned out and timing cover whipped off to take a look at the cam. Then hopefully a running engine.

I had to strip the box right down to get it all out; bearings were fine but it was all clogged up around the diff and particularly round the pick-up!

This is sounding more and more expensive… if I have to pull the diff out, I’m going to have to fight off the urge to get an ATB.

At least you never found out at 20psi I run a supercharger and I don't care the TB is on the wrong side.

From previous discussions I have had with Graham (off-forum, mainly by email over our EFi setups) I know he has a billet cam (hence why our EFi setups are different as his cam timing is different).

Probably worth checking the triangular thrust plate at the other end of the cam as lack of clearance on the drive dog could have pushed the cam hard against that bearing when the oil pump bolts were tightened. I’ve not got a picture of the thrust plate bearing side, but that looked ok. However…
This presumably is the result of little or no end float on the camshaft? Luckily I found this early enough this afternoon to get a new thrust plate and load of shims for the crank sprocket on order for guarantied Saturday delivery (ouch!). Once I have the parts I’ll check the end float and machine the sprocket collar as necessary. On 30th Apr, 2015 gr4h4m said:
At least you never found out at 20psi Ha, 20 psi. That would be nice. I only managed about 4.6Psi on the test runs, and to be fair that was disappointing. Maybe due to the high ratio of the 1st gear in the clubman SCCR gear set and 2.9:1 final drive, but I’d like to think it’s down to the special self-cleaning gearbox modification and possible drag on the cam shaft – if that would even be an issue. It was only down to my disappointment in the performance that this issue came up. I reset the waste gate actuator and was attempting a second set of tests on slightly higher boost the following weekend, which was when I found I had no oil pressure, otherwise this would have been found on the way to the MOT.

I would guess the clearance issue on the drive dog forcing the oil pump not to seat properly is down to the way the slot has been cut in the cam rather than differences in the pump shafts between a 1275 and a turbo version, I'm sure Leyland would have left plenty of clearance on all their setups because of their wide range of manufacturing tolerances. Those who manufacture billet cams may be more concerned over the lobe profiles than such basic stuff as slot size/length. There are other possibilities, like gasket thickness's, why the pump won't seat properly against a cam drive but there should be enough tolerance on OEM parts. Probably worth checking the triangular thrust plate at the other end of the cam as lack of clearance on the drive dog could have pushed the cam hard against that bearing when the oil pump bolts were tightened.

I concur about the thickness of the gasket between the front plate and block. The OEM gasket was very thick. It's been a while since I used a standard front plate so have no idea what is being supplied in gasket kits these days. This 'extra' dimension was something I had to take into consideration when designing the 16 valver engine seal plate that uses only a smear of RTV instead. Edited by Sprocket on 1st May, 2015.

on a side note, thinking about it, the thikness of the front plate gasket could also alter the cam lob position in relation to the followers such that they may not rotate as they should?................. On 26th Oct, 2004 TurboDave16v said:

I had 2 new Engine front plate gaskets in the gasket bin, one Payen which measures ~0.85mm thick and one from an FAI set, which measures ~0.44mm thick.

Not sure which make is which from the photo but one of those gaskets if for an "A" and the other for an "Aplus".

Actually, I think that looking into it more, both the above gaskets are for the pre A+.
