High Oil Pressure After Removing Oil Solenoid – Best Oil Filter?

[Koryak]

Keep in mind that the purpose of the bypass is to prevent filter sludge from starving oil flow. Decent quality oil & reasonable change intervals produce almost no sludge, even in short trip cold engine driving.

I don’t understand why a person would think an OEM filter couldn’t take whatever the pump can do. Kinda funny tampering with stuff like this and no clue what’s going on or will happen.

There are 2 groups of vehicle owners

1. There are enthusiasts who push the engine beyond its limits, and has verified that using other filters will cause no harm
2. Then there are other owners who follow by the book to make sure the warranty isnt denied

I ended up just using a GTR filter, zero issues!

Is the filter with the "E" designator a longer filter? I'm asking because that's the only reason I can think of that would allow more flow for the heavier weight oil.

Stock should be fine, or use the GTR filter if you're worried(they run ~ 80pis stock). You haven't increased the max oil pressure at all(~57 psi) so unless the stock filter was bypassing almost all the time on power you're fine.

The bypass valve in the filter operates of the pressure differential. Your higher oil pressure at low rpm/load shouldn't effect anything except gas mileage.

This is reasonable, stock Zs should be fine even with 5w30 in most situations. I will monitor when visiting the track next year, may go with the GTR filter if needed. If the engine is not pushed at constant high rpms, I wouldn't worry about modifying or removing the bypass valve.

I think the GTR filter is a the way to go especially if tuned and tracking. But that's just my 5 cents. I was very happy with the T&P’s after a heavy track session running a 5w40.

Yep 5w40 is what I normally use out here in hot west coast tracks, extra insurance.

Would running 0w30 cause any issues? I'm thinking about using that next oil change.

0w is going to be thinner on cold starts compared to 5w. 0w is for people who live in the North where it can see freezing temps.

Shouldnt be any issues running that oil viscosity

What caveats would there be in running constant high oil pressure with the solenoid deleted?

It's better to have the delete done, few articles around.. More preventive maintenance

Is deleting the solenoid easy for a novice DIYer or should I take it to a specialty shop?

Jack stands will do, just tight to get into. Hoist would be much easier. You will get a soft code that will need to be tuned out.
