Recently ive been having low oil pressure on my boosted jdm b16. When warmed up at idle its at like 7psi and a 3k its at 42psi. At idle it use to be at 15 but dunno what happened. I also cant hear vtec might be me but it cant hear it or its really hard to hear. Is there a way to check if vtec is engaging? Also will low oil pressure cause loss in power? Car feels a little slower than how it use to.

 

Generally speaking, what is the WOT oil pressure?

The bearings dictate alot on how the oil pressure is .. so it really depends.

 

instead of checking if vtec engages or not, check why your oil pressure is low.

1. oil pump
2. bearings
3. is there oil in the engine ?

 

Have a an oil radiator?

 

9/10 times its the oil pump. When you start the car up from cold does your oil light stay on for longer the usual ? If so take the pump off and inspect it internally... Something probably pass through it and scored it badly.
