Hello folks,
I am still haveing oil pressure problems. On idle when the engine is cold oil pressure is fine (with choke out). As the engine warms up the oil pressure starts to drop, this is fine untill Idling when the pressure is now on 0 snd the red light comes on.

Is it an air leak or something. I can't find anything wrong!

Which engine is this on? Last oil change? Could it be oil pump or faulty oil pressure relief valve?

buy some STP and put all of it in there! see if that helps and if so then change your oil!

I'd start by checking the relief valve. If you haven't made the switch yet, this would be a good time to make to the ball-bearing valve conversion. If that doesn't fix your problem... it may be oil pump time or worse yet, bearings. Yes, fresh oil and STP may help, but STP masks a wear problem. Even with old oil the pressure shouldn't drop all the way to zero. If your pressure is REALLY on zero when the engine is hot you shouldn't drive it at all.

1380.
I've changed oil filter, oil twice and I have the ball bearing and spring type release valve. i have already inspected it for C**p a couple of times

Faulty spring?

To be honest, big ends and mains.... even then this is no big deal, all you need to do is remove engine, strip box off the bottom, turn engine over, and strip out crank, you don't even need to remove the head...

But what I would do, as MMJ has said get some engine flush in there first, it'll clear our the oil galleries.

Helps if you have an engine stand :cheese:
