Thread: Help with this issue please

If your positive its oil, i'm betting its a pcv issue. Alot of people have had issues with PCV issues with Stg2 ICs. Is your IC the newer version? Did the LIM have slots machined in for PCV operation? Did you cut your S/C gaskets to mate up with the "new" PCV setup? If its an older set up, are you running an breather on the valve cover?

As for PCV operation, I honestly can't remember, I did my check with the help of PRJ like 2 years ago and I cannot hardly remember, I know mine is working fine though. From what I REMEMBER with the oil cap off (providing you aren't already running a valve cover breather) you shouldn't feel pressure there. Also, if you hear a high pitched noise that means something is up. You could (for experament purposes of course) install your oil filler neck and rubber band and/or zip tie a sock over the hole. See if that changes anything, this will act like a home made valve cover breather if you don't already have one.

I wish I had more memory of PCV operation, I don't though sorry. On my other cars I just deleled it all together and ran valve cover breathers. But on these 3800 motors the PCM will do funky things tuning wise without the PCV working right, thats the only reason my car still has a PCV system. Other wise i'd just have a damn breather too! LOL

You may contact PRJ or ZZP, go over you install with them, see what they have to say. If its oil though, my only logical guess would be the PCV system, i know many have had hell with this on the stg2 ICs so its definatly something to look into, know what I mean?

As for coolant, as long as the gasket surfaces were cleaned up good, and new orings installed I wouldn't know what would do it next. You did use brand new LIM gaskets when reinstalling correct? It may sound like I dumb question, but I know of a few people who have done this and I think its downright crazy IMO. Gaskets are cheap, replace em. Not that it matters but did you use the plastic LIM gaskets of the metal gaskets? Is there any coolant in the oil yet? Are you loosing coolant?

Another thing you could check too, pull out your PCV valve, shake it, make sure it rattled and ain't clogged with **** (like RTV). Hell, you may as well replace it, there cheap, like a $2? Be sure to save the o-ring. Check in the hole, make sure there ain't RTV gunked up in there. If there is, clean it out. I've heard of someone having an issue with there PCV a long time ago and it was because of WAY too much RTV to seal the S/C gaskets. Just a thought.
