Your IC gasket looks fine, it wouldn't cause it to smoke unless maybe your leaking fluid out of that core, test it... Where did you use rtv with that gasket on your IC? usually they run just straight up rtv or use a little around the edes of the inner core or any holes

You replaced the yellow o-rings on the LIM right? I know many peopl who have tried reusing them and ended up with problems.

Are you sure your PCV system is working correctly? That seems to be a tipical problem with the ZZP ICs.

As for the wet gasket picture, thats tipical of the POS Garlock gaskets ZZP sells. They are the worst damn S/C gaskets I have ever seen. OEM GM gaskets, especially the L32 style are far superior than those gaskets. In a few months those gaskets will get oil soaked and look really nasty, and thats with or without RTV, it doesn't matter. I hate those gaskets, I still need to get rid of them off my car. Worst "mod" ever.

If you even tear off your S/C again, buy OEM GM or Felpro gaskets, apply RTV on all 4 sides, and it will be good to go. GM L32s are the best, thats what I plan on using here soon.

something may need to be milled flat......

did you take a straight edge to make sure there werent any gaps before throwing everything back together? something could be warped and leaking in.....

EDIT:

as far as the coolant (whitish smoke) all you would need is a pin hole leak........

you said you see it more at idle? your not getting all the fuel from the injectors at that point, not like you are under boost.

...........

correct. or the IC is warped slightly. the only way oil is going to get into your combution chamber is from the valves, piston rings......

coolant would be from the intercooler, or the LIM.

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.
