Low mileage LS1 visibly burning oil!
Hey guys, I understand it's normal for LS1's to burn some oil, but I can literally see my car put out big puffs of blue smoke under hard acceleration.
Definitely doesn't do this each time I get on the throttle, but I've seen it quite a few times before. Not sure what to think of this. Always have to add oil to it in between oil changes too, this engine has only a tick over 24k miles on it as well if that helps.
No internal mods either, just has full bolt-on's and a dyno tune.
This sound like something to be concerned about?
Thanks for any help.

Yeah I called the guy who tuned my car today and he basically said the same thing as you all, I need to go ahead and get a catch can. Figured I would ask on here first though because I was worried it's consumption was excessive, thanks a lot guys

^^Interesting, I will have to look into that versus just installing a catch can, car is a garage queen so adding oil every now and then isn't a big deal but if I can stop the consumption completely that would be great

A new PCV was installed and the engine only used a half quart over the next 2k miles. Another GM known fact that will cause high oil consumption is a high RPM, low load condition. Put another way, if you are in first gear at 4000RPMs and not increasing speed, towing something or going up a hill, you will consume more oil. I do believe this was corrected on the 2001 model.

I didn't have any acute issues that I felt the catch can fixed but having a half quart of oil rolling around in my intake and a thick coating of sludge in the intake ports(head too) and on the intake valves I figured wasn't the best thing. I can tell you there is at least a 2mm layer of funk on the floor of the intake ports of the 862s I just took off of my 5.3. It ran fine but I have to assume that I was a little bit down on power because the port is actually smaller than when new. Also I doubt that oil in the combustion chamber falls under the category of "optimal." I guess my compression ratio probably goes up a tad every 20K miles though from the buildup!

Launching!
ls not using any oil fat chance they all seem to even the new LT1
My 5.3 has been a burner since the day I bought it off the lot
whats a qt here and there anyways no big deal. Hell at least they dont leak it bad like the old Gen 1s do lol
These things use oil make some not so great sounds...but seem to run good and hold. lol
On visible oil burning hopefully the above posts helped.
