Hi wonderfull people. I face a very big dilemna and i need your help. I've had my Z a year and the oil pressure has always been fine it's usually maintained high pressure. Over the last 2 months however it's reading very low and today it even said it was 0 at idle I looked at it and said fine if your gonna die do it now so I can just get a new engine but no.
The oil is pretty new and it's still full of oil what do I do?
I heard from a website the guages can stuff up what can I do to fix it?
Thanks Guys,
Worried Z enthusiast.

i had the same problem with one of my 260s. on the block where you screw on the oil filter you should find a ball bearing type valve. my had gotten stuck and hence no reading. all i did was { very carefully} when you have the oil filter off, gently push the valve with your finger to make sure it moves. it worked wonders for me. also, once on another z the oil filter bypass valve in the filter was screwed from day one,and it showed very low pressure at idle. changing the filter fixed that problem. give it a try, its a fast cheap fix if it works.

 

Well no point now cause the car was written off the other day but I'll rebuild that engine and stick it into my 240z cause it's got a P90 head great for turbo.
Thanks anyway.
