a few weeks ago i placed a revised cilinderhead a 924 from 76 2.0L
sinds then my oil pressure is low with warm engine almost 0

i looked at it didnt found any problem

now i was thinking maybe its a wrong cilinder head
an oil channel thats mayby bigger or something
i didnt know it but are there different cilinder heads thrue the years
( they both are european )
engine is from 76 could be that the cilinder head was from an 81 but dont know

The only thing I can think is that where the cams run in the head is worn.
The metal blocks bolted down on top of the cam are the cam bearing caps.

It's the only thing I can think of the would destroy oil pressure.

Other option - oil pressure sender wiring is damaged perhaps?

Did you replace the plastic elbow connector that attaches the cam oiler tube to the head? They get old, shrink up, and leak enough oil pressure to make the oil pressure gauge read low, even when they don't break outright.

You need to remove the valve cover, and the bolts that hold the camshaft oiler tube to the head, then pop the oil tube off to check the plastic elbow for cracks and to make sure that it fits down tight onto the head.

The plastic elbow is getting hard to find, so don't start the engine again, or try to remove the old part until you have a new one (not a used one) in your hand.

wiring of the oil pressure sender is ok i hooked it directly up to the gauge

plastic elbow is ok this is new i also removed the valve cover and started the engine to see if there is an abnormal leak somewere and no nothing everything looks like it could be

i was also thinking the cam bearing worn out but they cant be changed cous it runs directly into the cilinder head
