Okay, I added Mac's a month or so ago and ever since it has been smoking and drinking oil, it never before used any oil, I even wen't to NC and back last summer and racked up 1,400 miles with NO consumption whatseoever, the headers wen't on and then bam like that it drinks oil and smokes at WOT never at start up or idle or even driving but only at WOT and it is drinking about 1 quart per 1,000 miles give or take depending on driving habits, some say that they rebuilt their motors and it still consumed oil and smoked, all I wan't is to know how to correct the problem if that is at all possible? <img border="0" alt="[bang head]" title="" src="graemlins/gr_banghead.gif" />

Talk to JPR; he can build an engine that won't burn oil after a rebuild. Mine doesn't.

Bigtime at 36K on the motor.

Rings. Mine is a 99, consumed oil after headers went on.

Do a leakdown test on the engine instead of guessing. It will tell you where the pressure is leaking from and from which cylinders.

I did one and it showed three bad cylinders. All 3 pistons had busted ring lands.

This may sound silly, did you put the dipstick back in? <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

I have an '01 that has never had any noticeable oil consumption between changes. Car has 13,500 miles on it now. Broke it in on dino oil, and switched to Mobil 1 10-30 @9000 miles. Never messed with the PCV system at all.

My '99 NEVER had a oil consumption problem at all! I would NEVER have to add oil even between the 5,000-6,000 miles between oil changes (using Amsoil 10W-30) it never smoked any whatsoever either! I added the Macs and it was as if a switch was flipped somewhere, it started smoking and consuming oil within days. The headers did cause this as many have stated the added power found a weak link which appearently was the cheap junk rings that we all have in the LS1. I have no idea why some cars develop this problem after a header install while others do not? my buddy put Macs on his Z-28 at nearly 90,000 miles and it doesn't use a drop of oil or smoke but yet when mine went on at 54,000 it started right away! I am going through atleast 1 quart per 1,000 miles now with no changes other than the headers. No choice now but to re-build a perfectly good running LS1 becasue it smokes at WOT like a freight train, either that or just keep driving it like that.

LS1JAY- no, the car doesn't have headers (yet <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" /> ), so it's difficult for me to make a direct comparison.

If I were you, before I tore the motor down I'd put a LOT of work into the PCV system, though... LS6 PCV valve, catch can, whatever; it's a hell of a lot easier and cheaper than a rebuild.

I also have those headers and also notice smoke at WOT...do you have the OYP or cats? also I've not noticed a drop in my oil level yet but then again i've had them for a week so I guess I'll be checking often

I really wan't to keep it but a few have said that a re-build did not cure the proble, I don't see how unless something was not done right during the re-build? a re-built motor should be better than new even. <img border="0" title="" alt="[Confused]" src="images/icons/confused.gif" />

I don't see how a rebuild won't cure the problem. It could be just plain ole coincidence that at the time you installed your headers you began having oil consumption issues. Rebuild it, I bet it won't smoke anymore!
