Found my problem. When the h/c swap was done some collant was left in the bolt holes for the heads in the block. When they were tq'd down they cracked the block in the back

That's no good Joe...Did you have the smoking upon start up and acceleration? I always see a decent amount of smoke when i crank the car and also when i floor it. We could share the same problems. <img border="0" title="" alt="[Sad]" src="gr_sad.gif" /> Either way, I know something bigger and better is coming out of it. Good luck <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

Stage II heads, C1, 918s. Oil consumption really started after header install. Dont think its any worse since H/C install. Slight smoke at start-up, some under heavy accel, and some on decel. Uses a qt of mobi1 10-w-30 every 600-800 miles. Car is at track once or twice a week. Over 900 passes, and 51k.Get some KR 1.5-3.5.Put the new PCV , no better.Car runs great, but I REALLY hate the smoke!!!

My car was smoking sometimes when I got on it. Recently I put an oil separator in and as of this morning, I put a Metco breather.Now I don't see any smoke what so ever and there hasn't been any oil in the separator since the breather went in.

<strong>Well, I know the engine that I have been having the smoking/oil issue with is not an LS1, but I did get mine straightened out. Took it to the track the other week, and it didn't do as good as I expected, and seemed to be smoking a bit more then usual. Spent the next day doing a compression test followed by a leakdown test. I figured I would find a bad cyliner or something, but everything turned out to be in excellent shape. So I spent a couple nights last week swapping my teflon valve seals for some rubber ones. Fired it up and no more smoking. Had it out last night so I could check in the headlights of cars behind me, and no more smoke. Hopefully some of you other guys have had some luck.

It smoked ALOT, and I mean ALOT at WOT though!! Thing is, I never could have known it was cracked until I yanked the motor. Can't see back there or even really get your hand behind the #8 cylinder.

Well, I haven't done a cam in my car yet, but there are only so many places oil can get into an engine from. around the valves, past the rings, through the PCV, and around the head gaskets. I've seen people say they've checked all of these except the head gaskets. It wouldn't surprise me if the stock gaskets couldn't take the abuse of the big cam. The first time you would the motor up the cylinder pressures could ruin the seal between the block/gasket/head somewhere and whammo you've got oil. Of course, if the gasket only lets stuff by at WOT, a compression test in your driveway/garage won't show dick. It'll look fine, a leak down will look fine, etc... There's no way to duplicate the kind of conditions WOT produces in your driveway with a guage hooked up.

We've seen one or two smoky engines solved but each one was because of something different. One guy had bad valve stem seals, one guy (poor guy) has a cracked block, but some of you guys are getting oil in every cylinder and I can't believe you have 8 cracked pistons, 24 bad valves, or 8 bad valve stems seals. 2 light-duty head gaskets is plenty believable though especially considering the bang-up job GM did with the clutch and rear end. It's obvious they weren't planning on us making real power without replacing some of the wimpier parts.

Like I said, I don't have this problem, but I would really like for someone to try slapping a new heavy duty set of gaskets on their beast to see if it clears anything up. I'd like to see this issue solved before I start building my motor and I'd REALLY like to see you guys start enjoying your cars again.

was cam throughly cleaned before install? cams are usually coated after grinding with a antirust coating for shipping/storage sometimes they don't get cleaned that well after grind/polish &inspection. they get coated and trap any left over debris at coating process . clean all cams thoughly with solvent before lubing up to install carb cleaner then brake clean work well also ya didn't say if timing chain was done also. if yes you also should clean and never install dry i have seen plenty of low mile worn gears due to being installed dry .wonder were all that metal deris ends up?

Usually valve guide seals are responsible for a puff of smoke only at startup. Matter of fact, every car I have owned before the 98 and 01 SS's did that. So if its only at start up, its your valve guide seals. If its at wot, its something else.
