I picked up another Z TT yesterday.Drove the car back from Devon to bournemouth for 3 hours. Everything fine. Noticed however that the oil prssure gauge was reading zero !! Not budging even under heavy revs.

 

An RAC man who I happened to chat to at a garage(I pulled over straight away) agreed with me and said, the engine sounds fine, the turbos would have seized if the pressure was genuinly that low. He estimated a dodgy sensor or guage.....however, on starting cold this mornirng with thicker cold oil....., the guage sits on zero but pressure increases to 4 when revving. As it warms up it stops moving up the scale again...

 

i am stumped as the car seems to run perfectly. the cams, tappets are quiet, turbs spin up, there is a lot of power?

 

help anybody????? Where is the sensor on these car, crank case???

Hope this helps. http://www.300zx.co.uk/forums/attachment.php?attachmentid=48701&d=1244587100

very poor sensors on zeds mate. Happens to a lot of them. Some have relocated sensor, replaced or got aftermarket gauge to read better.

Yup - that's definitely the sender unit going bad mate!

 

They are quite expensive though (what isn't on a ZX); around £80-ish + VAT for the part.....:helpsmilie:

 

Don't bother wasting money on a 2nd had one; speak to Mike at MJP for a new one.

If you know your engine is fine then i wouldnt worry. Mine was dodgey when i got my car. then after a few oil changes and over time it started to work lol!!!

 

Still goes funny every now and again but 90% of the time its good :1eye:

Thanks for some good advice, I thought the engine was on its way out so I am VERY relieved indeed!!!! Will upoad some pics of it later, a new project in the making :)

Mine use to go to near Zero as well mate, i got aftermarket, it works alot better.

frightened the crap out of me I have to say!

the wipers inside the unit dont touch very well with the old age, I took mine apart and fixed it, but its a sealed unit so not relly designed to be done. Worked fine after though.
