M30b35 Oil pressure problem ?

[jc971]

Hello
I think I have a problem with the oil pressure in my engine
when I remove the oil pressure sensor in the cylinder head, I activate the starter for a few seconds but nothing comes out
then I remove the oil filter and activate the starter and the oil comes out
I replaced the oil filter support of my late m30b35 for an older one, and the gaskets do not really match, can my concern come from there?

I will recover the original filter holder from the m30b35 and compare them

At the bottom of the small elongated cavity shown in your bottom picture there is a threaded hole. Plug it with an internal hex drive 1/8th pipe plug. This will restore your oil pressure. Right now it is all bleeding back to the sump through that hole.

Hello
thank you for your reply
If I understood correctly

at the bottom of the left hole, the smallest, there is a threaded hole in which I can put a screw to force the oil to rise

I had thought of putting back the original oil filter support to solve my problem

A 1/8th NPT pipe plug works perfectly. Get the internal hex driven one because you can't get a wrench in the hole.
