Oil Leak

[rwebster60851]

Hi I have a 944 1986 2.5 Lux

After a long drive the next time I started the car it emptied all of the engine oil out of the filter, which was lose by about 4 turns, I just thought that it has made its self loose so put a new filter on and filled again with oil but it has happened again.

Do any of you have any ideas before I take it to a specialist.

Thanks

I IRC there is a steel threaded insert screwed into the block onto which the oil filter screws.

You may find this bush has got loose when a very tight oil filter unscrewed it a little rather than initially unscrewing off the bush.

If so it needs resetting in the block casting using a Loctite or similar threadlock & screwed in really tight-using something like a strapwrench to grip it tightly without damaging the threads or 2 same thread locknuts tightened against each other on the bush.

Leave over night before refitting a new filter carefully ,enough to seal but not too tight that it moves the bush-smear a little oil on the filter rubber seal to help.

You might also have an issue with the Oil Pressure regulator valve - Ed Hodgson had this happen to his S2 with similar symptoms

Well if it's any help, the oil pressure regulator valve I replaced on my 944S due to a oil leak on the cooler housing. I used the wrong "alignment drift" to align the OPRV in the cooler/Engine housing, so with this and the resulting high oil of pressure placed on the oil filter it was something else (it sounded like a champagne cork going off) within seconds it push the rubber seal out of the oil filter and vast quantities of oil too! Possibly any alignment issue with the OPRV may be a cause ??
