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.

Honestly a lift will not be to helpful. You need to lift the engine up a little bit with a cherry picker. Then unbolt it from the subframe. Next it taking off the oil pan. Then oil pump. The hard part is putting the pan back on correctly.

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+.

What are you bearing clearances?

Are you saying your pressure drops 5 psi when you run anything less than full retard?

I honestly do not remember what my bearing clearances were. I know they were within stock spec.

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.

Maybe this helps. ~70psi during WOT pulls. It's the red graph. You can actually see the pressure going down as the oil temperature goes up.

What software are you using to log oil pressure? Maybe I need to figure out how to get MS to log it.

I don't understand why you are pulling the motor then. I had a long talk with clevite or king-- I forget. I was telling them that I was considering pulling my motor because I had somewhat low oil pressure, stock bearings, and was heavily boosted. They emphatically suggested a) looking at the oil filter/oil for particles and b) doing an oil analysis. They said that if there are no particles and the analysis comes back ok, don't worry about it.

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.

Ahh makes sense, thanks.
Perhaps I should do a track day then send the oil for ----.

First I was like.... :hustler: but then I :laugh:
