Re: Oil rings affected by cam install? well the cam would not change the oil burning in my opinion,however putting the wrong seals on it would.I would change the valve seals again, I would almost bet they gave you the wrong valve stem seals.very easy mistake to make.
Also with oil in the chambers it will detonate like mad.it is real detonation,you will damage stuff if you dont let it retard the timing.

It now used 1 qt. every 50-75 miles and smokes alot when under hard aceleration. I am imbarassed to even try and race it people might think I am spraying for mosquitos. The car has a lot of valvetrain noise but I guess it is due to the cam which has a 569. lift. My warrenty is voided so I on my own.

only difference between our car is the mileage, yours is low miles, mine had about 62k on it at the time of the cam and header change.
we will figure it out in time, just hope it doesn't break the bank before it happens! <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

Re: Oil rings affected by cam install? I am going to watch this post in hopes that someone can come along and clear this up for us. I did do this, after the cam swap (which did not involve pulling the heads) we found a worn valve guide so we swaped on a set of newer 2001 heads factory dressed and the problem was exactly the same no change. The casting # on the 2001 heads and my 2000 heads was the same #241. The 2001 heads were not new we just tried them to see what would happen, I think they had about 15k on them also.
I also tried the open PVC valve, no change. Now I am just trying to whittle away the payments to trade her in. I am also on my 3rd tranny and second rear end, 3rd set of gears. By the way the car has never seen a set of slicks these GM cars are just over horspowered peices of glass, gotta be carefull or something will break.

Re: Oil rings affected by cam install? We are making progress on the knock retard problem. Almost reduced it by half of what it was so we are making some progress.
The oil smoking out the rear is still there. I believe Brian is going to performa leakdown test in the next two weeks.
We are going to stay on this till we figure it out or go crazy trying. There seems to be more and more of this exact problem popping up every where.

Re: Oil rings affected by cam install? Maybe we should make an email list so we can email out updates. That way you know when something has happened and don't have to remember to check this particular thread every day.

Re: Oil rings affected by cam install? After further reading I am going to agree with Team ZR1 on this I think he is on the right track with car being real lean I have seen them smoke like a freight train in carburated cars when tuned to lean

Re: Oil rings affected by cam install? To every one having this problem,
What cam and springs are you using?
It looks to me that every one having this problem has alot of Der. Is this the case?

Re: Oil rings affected by cam install? Yo peeps!
Just another smoker checking in....
I just switched to a synthetic blend, I still seem to burn a quart every 2,000 miles or so. I used to use A LOT of Mobil 1. Anyways, I can't tell exactly what color my smoke is @ WOT. I will ATAP the car this week....
Stock heads/intake....T1 cam here
918 springs/titanium retainers
Macs

Re: Oil rings affected by cam install? I just wanted to add myself to the list for this exact same thing.
I have a 2000 SS, and went with ported heads and the Hotcam, it makes awesome power, but smokes on WOT. I use about 1QT every 1.5 weeks. more if I get on it alot. I was thinking about going with some Total Seal gapless rings, but I want to know what the problem is before I go to that trouble and expense.
I do not have any knock retard though, at least none I have seen on A-Tap
It really pisses me off to have a car that smokes. Looks like a junker.

Re: Oil rings affected by cam install? Thunder 224/112 with 918 springs (had 941s, swapped them out, still smoked anyways). Changed valve seals at the same time, didn't do anything. Removed PCV system and put a breather on each valve cover. Slowed oil usage a tiny bit, still about a quart every 1500 miles and still smokes on WOT.

Re: Oil rings affected by cam install? Let's list the brand and type oil you use and how many miles on your car (or engine if you have built you a new one since you got your car).

Re: Oil rings affected by cam install? Wizkid,
How many of the cars that are using oil after a cam install, also had an under drive pulley installed?
Theory:
Lightweight underdrive pulley can't dampen the harmonics properly, resulting harmonics cause increased flutter of the light weight oil rings, resulting flutter causes increased oil consumption.
I know this wouldn't apply in every case but could it apply in some cases maybe it's the increased cylinder pressure and increased ring flutter that causes the problem.
It's just WAG...Wild *** Guess...

Re: Oil rings affected by cam install? Go to your local racing engine buolders and ask if they've seen this. More than likely they haven't worked with LS1's that much but maybe they'll know the problem. I'll ask my friend who works at one and see what he thinks. This is disturbing since i am thinking of doing a cam and would hate for it to smoke like crazy. Two of my friends of done heads and cam swaps and have had no such problems though. Sucks when your that 5% that the bad stuff happens too, doesn't it?
