I know a few are out there on the market, but aren't they just a spring, spacer, valve, and gasket?

What weight oil is recommended once one of these is installed? ZZP recommends 5w30.

I am running the Intense kit with 10W40 and I am seeing about 80 psi on the gague.

The INTENSE kit has the washer to preload it a bit more than the spring alone. Not sure if the ZZP kit does that.

Just checked, they don't. Hard to say if either kit is better than the other, but I run the INTENSE kit and run about 85psi cruising in cool weather, 75-80 on hot days. I run OEM spec just like the oil cap says to run.

I know SDD recommends 5w30 as well. There kit also plugs some hole and bypasses some sort of oil bypass (no pun intended).

Might just be an anomaly, but for what it's worth, I installed the Intense kit and didn't see any improvement in oil pressure at all.

Hard to tell with the Canadian gauge what the pressure actually is, but it's still where it was before the kit. The needle about 2 widths past straight up and down at cruise and about 3 widths below when warm idle.

I agree....to clear the air here, there's a big difference between oil pressure kits and bypasses. Raising the pressure is one thing, bypassing is a totally different animal.

Easy short answer. Dirty oil is better than no oil.

I run the ZZP kit. No spacer, just a correctly calibrated spring.
80 psi and I use the recommended 5W30 oil.
With the higher pressure, the engine can live with a little lighter viscosity for a hair less drag losses = >hp.

I'll have to tell that to all the people who have had turbocharged400sbc (twin engine cutlass) install those kits on there motors.

My understanding is that on some imports and other various car it can be dangerous to bypass the bypass, but as far as I hear on a 3800 it opens at 12psi...which is near nothing. So bypassing it on our engines will not cause issues.

"Robert" or Bob as i always thought his name was is on here. I'll shoot him a PM.

Two different engines, on my S/B I had the oil bypass blocked but I used two oil filters that held 2 quarts of oil each(Baldwin B7 filters). When you have big filters the oil will flow even when its cold(40 deg) out. With the small filter that is on the L67, it can't flow as much oil as the engine needs and then you will run into problems.

No I mean on 3800's. The guy with the twin engine cutlass has been putting these kits in the 3800 build's he's been doing for some time now.

Paul,
Thats because you can do it yourself for the cost of the gasket and a couple of washers with the stock spring.

I have never seen or heard of a "kit" that disables the oil filter bypass.

The 12 psi is from the high pressure(inlet side) to the low pressure(outlet side) of the filter. In other words if you have 60 psi going to the oil filter and the oil is cold or the filter is dirty, then when the psi spread is greater than 12 psi(48 psi on the low side) part of the oil will bypass the oil filter and go directly to the engine without going through the filter first. That is why its a good idea to use the biggest oil filter that will fit(less oil going around the oil filter and more oil going through the filter). If you disable the oil filter bypass all or most of the oil will "not" be filtered, if on the other hand you increase the psi that it takes to get into the oil filter bypass mode then you can starve the engine as the rpm's increase(not enough oil can get through the small filter that is on the L67's). Don't confuse oil filter bypass(lets oil go arond the filter and lube the engine) with oil pressure, two different things.

I use the Delco PF52 on mine. A lil bigger. I need to put in my Intense kit here one of these days.
