camaro 3.8 oil mod

[camaro211z28]

I was on v6fbody forum and read something about a mod in the oil filter filtet housing to allow more pressure due to the unknown 3&4 spun rod bearings in these motors. Was seeing if anyone has any info on it. Didnt find any help or infoon other forum

Re: camaro 3.8 oil mod

Could block off the oil bypass... I know some turbo guys do that since try tap the oil feed from the sending unit, and how the adapter works, it sends more oil that way with it blocked.

OR, I know ZZP sells an oil volume kit, and a Melling oil pump. I've got those, and absolutely no issues.

Re: camaro 3.8 oil mod

I was sold (unknowingly) a junk yard engine and I was getting low O.P. never got to 60.
Went all the way into red area when engine was really warm. I changed to 20 W -50...brought up oil pressure and I have had no problems. I would not screw with the stuff you are talking about...make a mistake and it could be very costly. There are many posts on here of people trying stuff they are certain about and really screwing up their engine...$$$$

If you're that concerned with your engines oiling system do what doctor did and upgrade those items. Don't try milling a very important piece. You could end up doing a lot of harm.

Re: camaro 3.8 oil mod

Well I will do what is best. But I would like to do research and learn what people are doing to there filter houseings to mod it. So I just took the oil filter housing off the timing cover. Would you do this mod to the filter housing itself or the timing cover ?

Re: camaro 3.8 oil mod

When I first got my car, I had issues with my oil system. There's a few threads of mine on the topic, around this forum. I used various additives and they did very well as a band-aid, but I knew there was am underlying issue.

The oil pump on the 3.8 is driven by the crankshaft, and in mounted in the timing cover. Simple enough to replace... the oil volume mods are in the pressure spring that mounts in between the filter adapter and the timing cover. The bypass, which I'm assuming is the mod you're referring to in the adapter, is a small valve under the filter spindle on the adapter. Your choice is your own, but for a mildly or less, modified car, get the new pump and volume kit. Its $70 roughly and takes an afternoon.

Re: camaro 3.8 oil mod

Anyone else sell an oil volume kit besides zzp? Yes the mod im talking about is the ball amd spring. People say it needs to be removed and open up the hole a little more

Yes , thats the kit.

Re: camaro 3.8 oil mod

I've never seen a ball anywhere in the system...

I believe the little ball thing goes in first then the spring, I can't find my kit at the moment.

Re: camaro 3.8 oil mod

If I block off the oil bypass valve in the filter housing then there is no need for the spring in the front cover and I wouldnt have to buy it from zzp right?

Re: camaro 3.8 oil mod

The ball does go in first.

Re: camaro 3.8 oil mod

The oil filter bypass is mainly for cold startups when the oil is at its thickest.

Issue is it allows unfiltered oil into the system, this especially when mixed with cars running long in the tooth and a sludged up engine can lead to premature failure of the bearings. Add performance mods like nitrous or forced induction that increase pressure in the cylinders and you have effectively increased your chance of grenading the motor.

This can effectively get wedged open by sludge/debris, and just allow unfiltered oil without any restriction. There goes the mains. There's a guy on another board that I think went through 3 junkyard engines, low miles, all spun bearings. His bypass was bad as he was reusing the one from his first engine.

My engine has the oil filter bypass blocked off with an npt fitting. The machine shop knew what I was wanting, the machinist in charge actually did the same things on his race motors. This block was completely cleaned, honed, align bored, balance shaft deleted and blocked oil passage and hot tanked. It had bad oil sludge at 130K miles. I changed the oil at regular intervals with synthetic for the 70K miles of ownership up to the point where I tore it down. It's best to use a larger volume filter. I use the ACdelco PF52 with the metal core, not the PF52e which has a plastic core.

If you don't know what you're going after it's easy to screw up the wrong thing. It's best left to those that know what they're going after. Most engines are fine with a proper refresh and installation of quality parts in a clean manner by a knowledgeable mechanic or with a skilled friend that isn't going to do a shoddy job.

You mean like putting Bars Leak in the engine?

Re: camaro 3.8 oil mod

Ok so it is what I thought. You just drill out the bypass valve and plug it off with a npt fitting. But when you plug it off then the spring and ball are no longer needed then right?
