Hey all. Not 100% sure this is a FI related problem but since I have the least amount of experience with the Maggie, I though I would post it up here.
What I have is a 03 5.3L with MP122, 3.1" pulley making 9.5 boost. The engine is 100% stock. I have 15k miles on the charger and a total of 50k miles on engine. The last 8k-10k miles I have been loosing oil at a rate of 1 quart per 3000 miles. There is no visible leaks of oil any where. No smoke at idea or start up but on a WOT punch I get a "Puff" of Gray smoke out exhaust. This is a DD and I am very easy on it... Should I be worried about this? Is there anything I should be changing or doing? Is this normal? Any info on this would be helpful. Thank You! Tyson

you need a catch can...you are pushing oil through the pcv under boost into your intake

Sounds like he needs the catch-can and the older style PCV check valve.

I was almost 100% sure that was the case but wanted to be sure. Any suggestions on brand and type of can?

Catch cans dot com is where mine came from.

my truck does the same thing and i am NA. When i start driving it again (deployed) i plan on installing a catch can as well. It is very common, even normal on gen3 gm vehicles to consume up to a quart each oil change. I wouldnt worry too much
