Hello guys,

In the past couple of days I've noticed the Z has low oil pressure at start-up when warm. The first time it happened the gauge sat at about a quarter for a good 2-3 minutes before it shot up to the normal oil pressure. Last night I started it and it sat there for a few seconds and then rose. Any ideas on what it could be? I did an oil change yesterday as I was thinking it was an oil problem but nope still has it.

On another note, what could cause a squeaking noise when the car first starts when warm? Belts maybe? Can exhaust squeak?

Thanks

Jan

First thing to do is replace the oil sender switch.

Belts can squeek or squeal.

First thing I'd do is clean the contacts between the oil sending unit and the wiring harness. A little emery paper and clean them to bright shinny copper. Then make sure there is a good tight fit between them. Check to make sure the wires aren't frayed/broken etc. If that doesn't help - replace the oil pressure sending unit.

FWIW,

Carl B.
