LS 5.3 DOD AFM oil consumption

[1quick]

I'm thinking gm 515hp ls3 crate motor

My GXP burned a quart every 1,200 miles and the dealer would do nothing about it under warranty. I just learned to always add oil to my car like it was a old beater till i traded the POS in.

Irronicly I've been looking for a 9-7X that needed work for cheap.... Hmmm

Buy it and put that ls motor you have in it, I've always wanted to put a ls7 in mine but side projects got in the way

Sold it. But there is other motors out there. Id also be taking it to 2wd land.

Your talking to the right guy about getting cheap cars and fixing them.

That's what I did for the last 5 years of my life.


I did find something out last night after doing research, these saabs/4wd trailblazers do not have the oil relief problem in the pan since they have different style pans than the other trucks(obviously) but the relief valve is not in a spot where it sprays the pistons.

So I will be looking at the Pcv system and doing the top end clean this weekend.

I wonder if [MENTION=109]TommyGloves[/MENTION] has had this problem?

I did have this problem on my 07 9-7x. I bought the AFM deflector and was going to pull the pan to install it. After looking what it would take to pull the oil pan I said fuck it and ended up using my buddies HPT to disable the AFM. I did do the top engine clean, new plugs and new wires at the same time.

It's been about 2 oil changes since it was disabled and I'm only down about a quart every 6,000 miles. It cut oil consumption down by over half.

HTH

IIRC the '07+ 5.3s already had a modified drivers side valve cover. It was only needed for the earlier years.
