Hafael Posted March 21, 2021 Share Posted March 21, 2021 Hi Guys, I have an issue with high oil consumption on my 350z. I have done compression test and all 6 cylinders are around 185psi on the 6 stroke during test so it seems compression is fine. I dont have a compressor to do leak down test which would be more accurate. Car drives well but I am worrying it might be problem with rings or valve seals. I took pictures of the spark plugs (do they look like car is burning oil?). I wonder if anyone here had similar issue and is able to give me some advice?

Ekona Posted March 21, 2021 Share Posted March 21, 2021 (edited) What 350 do you have? DE, Revup or HR? And how bad is the oil consumption? Edited March 21, 2021 by Ekona Quote Link to comment Share on other sites More sharing options...

(ie so many miles per litre of oil) That is the only way to get an informed answer to your question. What is the mileage of the car? The plugs look fine.

Can I take readings from the dipstick or will I need to drain the oil? Quote Link to comment Share on other sites More sharing options...
ZMANALEX Posted March 22, 2021 Share Posted March 22, 2021 Dip stick will be fine providing you check before and after readings on a level surface and when cold. Quote Link to comment Share on other sites More sharing options...
