Greetings

Long story short - I am once again the proud owner of the car I sold 9 years ago.

However she has come to me with a fresh set of problems.

Biggest of all is the loss of oil pressure. I'm told the needle remains at zero with the occasional flicker of life, the sender unit was swapped with a known working unit which made no difference. I have not seen this myself (above info from the last workshop that worked on her)

Cranking over also presents no rise in oil pressure.

Removing the oil filter and cranking over results in oil pouring out the filter block head.

Can someone shed some light on the oil circuit for me? I understand her to be the "bypass flow" variant. Does the oil filter block contain C37888 or will I only find this valve located on the sandwich plate? How does it differ in function to EAC7149? Am I correct in understanding that EAC7149 controls the oil pressure feed to the engine bearings etc?

Thanks in advance
Nathan
