yes, that was my thinking - the more volatile stuff evaporates, which would lead to a higher flash-point. Will try that. thanks for your help!

can old fuel be an issue? do the flammable components evaporate over time and render the fuel bad?

A stromberg I found that I still had new points and fitted them - again a slight improvement, but overall the problem remains.

Hello all - this is for a petrol 6-cyl from 1974. I am aware that there are similar posts as what I am going to write, and I apologise for this. But the advice given there did not do it for me (so far?). When I start my engine it usually starts fine but runs very rough and stalls after around...

It has been a while... But I just finally gotten around to installing a mechanical manometer, and unfortunately it confirms the measurement - the pressure with the PRV closed goes to beyond 10 bars! (see attached photo) I guess I will drop the sump again and remove all the bearings to check for...

Good idea - or hook it up to a different (stable) 12V supply. On the other hand, the temp sensor/gauge seem to read correctly, and this would be connected to the same power line as the oil sensor...

Just a short update - problem is not solved. I double checked all electrical connections on the pressure gauge (voltage reading 11.8 V with engine off), they are fine. Today I finally ran the engine up to temperature - the pressure stayed high but again dropped when I loosened the nut on the...

I will get a new spring in any case (hope I can find one at a local LR workshop, shipment from the UK is nearly impossible these days - so much so that I ended up with two sets of main bearings and two sets of big ends...). But I must say that I am relieved (thanks for the pun ;) ) that today I...

I need to think about this... I could also just cut the spring in half (approximately).

Another way to get the oil pressure down would be to remove some of the oil - but I also don't really feel comfortable with that...

I guess I could, and that way I can at least drive the car. But that is not really a satisfactory solution.... I would like to know what is wrong, and why - and I want to make sure I don't blow out the oil galleries or the filter housing at some point! :)

However... (wait for it...) i tried again to loosen the relief valve spring, and this time it had an effect! The pressure initially rose to 100 psi but then suddenly dropped to about 60-70! So the valve does seem to open, just now how it should. I was hoping that this might have released...

i know that 8 out of 14 have holes, and all my old ones do. So i conclude that also the new ones that i did not re-check have them ;) Unfortunately there was no miracle. Car started (had to wiggle the distributor again), but the pressure is just as before.

checked the spring - it compresses correctly, as fas as i can tell (my rig was sort of rudimentary; packs of sugar suddenly get a new purpose :) ). The plunger in my case had a slight mark from the ball, but i dont know if that is from now or from before. I tried to wiggle it back and forth as i...

see my last message about the bearings and bottom halves. I guess i will need to test the spring. But i think if it is the relief valve it would rather be a misalignment issue. The ball moves freely in its seat, but maybe the spring somehow pushes in a funny way.
