Ask Your Own Infiniti Question

did you check the oil pressure with the engine hot ??

Ask Your Own Infiniti Question
Customer reply replied 24 days ago
No i haven’t i heard about that but no oil light on or chain noise if that matters
Customer reply replied 24 days ago
Also the gaskets that are know to leak oil in the rear timing cover that cause the pressure drop i did remove and use sealer on them

t​he light will not come on and the chain will not make noise . when you remove the lower oil pan did you inspect the contents in the pan ?

Ask Your Own Infiniti Question
Customer reply replied 24 days ago
Nothing out of ordinary in the pan

sometimes you can see I small part of the oil galley gasket broken off in there

Ask Your Own Infiniti Question
Customer reply replied 24 days ago
Ya nothing in there but i did reseal the oil galleys

I​f you have replace all the part that you did not the electrical for the solenoids are good then you most likely have internal oil leak cause by a broken/leaking main oil galley gasket on the rear timing chain cover.

Customer reply replied 24 days ago
rear timing cover

yes the sprocket can cause this it is really the only other thing that can

Ask Your Own Infiniti Question

Ask Your Own Infiniti Question
Customer reply replied 24 days ago
If u run it on are scanned it shows the bank 1 timing at 0-4 and bank 2 at 41

I was in trouble with an electrical issue with my brand new Nissan. I frantically went online trying to find help and luckily I found your site. I reached a NISSAN tech named RIP. He was absolutely tremendous and helped me work through the issue. What a pro!
