oil light

Just another question, being a auto how do you find your 3'' exhaust going down hills towing not so much 4wding in low range but highway up and down hills does motor want to over run at times, and did you refit catalytic inverter or just straight thru no muffler. cheers

Fitting oil pressure gauge and boost gauges with alarm today, also replaced both high and low oil sensors lets see if problem persists,

All I can say is be careful if adding to much weight to the oil sender banjo bolt, mine was found to be stripped from a previous attempt or different sender had to manufacture a longer threaded bolt for oil sensor to screw onto, lots of upside down and looking at opposites thru mirror.
Best thing is it works and have gauge to see oil pressure not just that silly oil can light.

What's the oil pressure psi my zd30 should run at moment idle and up to running temperature it shows 2- psi
acceration 15-20 psi!
Spoken to Nissan don't want to know about, and other people have same figures
Just a concern when doing slow turning twisting saying no oil
but oil dipstick shows full. CRD ZD30 3/2007 any advice greatly accepted cheers

hi , seanz .
manual says ; idle 21 psi . 2000 rpm 78 psi . 4000 107 psi . sounds like you have a problem with your oil pump system , maybe needs adjustment or perhaps bypass valve is stuck open . never had problems with this before myself so don't know how to tackle it atm . hopefully others can help .

Thanks for those psi numbers, Mmmm sounds like another one of those jobs you learn as you go along.
Oil relief valve probably in a great spot to work on too
cheers for the research!
