oil pressure, VVT head with non-VVT (thin) oil pump
#21
I have access to a lift.
What's the easiest way to pull the oil pump?
It's high RPM oil pressure that's important, as long as idle has > 10 psi.
I barely get over 30 psi hot at 4000 RPM. 5w50.
My main bearing clearance are ~0.0028 - 0.0032"
I have a 91+ real OPG which I verified with another gauge.
shuiend,
How much does your OP drop when VVT "kicks in"? What do you mean by "kicks in"? AFAIK
faeflora,
I did an oil anaylisis at 3000 miles and it looked "normal" for an engine that's <5000 miles since a rebuild. I hadn't been revving the engine all that hard.

If you have help there is no reason why you could not pull the motor and replace oil pump in a weekend.
My oil pressure seems to drop about 5psi when VVT kicks in. Still well above 50psi+.

Oil pressure seemed to drop about 5psi when the came were not at full retard. My vvt has not been tuned yet at all and I was going off settings I got from y8s, so that may change. I know when I had VVT disabled my oil pressure would not drop any.

Honestly, I do worry about it but their recommendation makes sense to me. Do you think otherwise? I am open to persuasion on this matter.
