Hey TYF! Mostly been lurking for the past few years; long time, no see...but I'm back and excited to report that I'm moving up to the GMT900 platform later today - via being gifted/loaned the black 07 LTZ in my sig during a cross-country visit from my folks. My family has christened him with the name "Rico Suave" or just Rico for short. I'll have to post pics soon, but take my word for it: for 225,000 miles he's a beautiful and well-cared-for truck, garnering compliments from the DMV folks who did his inspection today. Transmission fluid and both differential fluids were all just changed to synthetic prior to his drive here, the Michelin LTX's he wears have been rotated religiously by Discount, the infamous oil pump screen has been cleaned once (a few years back) and then replaced (last year).
However, we've got one somewhat significant remaining issue. My father reports that he not only leaks oil (which I could plainly see on the underside /crossmembers of the truck when I took a quick Spider-Man pose under it at my folks' hotel), but that he consumes oil to the tune of a quart and a half between changes. Yikes!
My question is this: I have an Amazon shopping cart full of upgrades for Rico, including the updated valve cover and the Moroso GM-truck-specific catch can. He's also had dino oil for his entire life, which I plan to switch to M1 synthetic tomorrow with an M1 filter, the longer optional size like I've been running on my 04 Yukon. All other things being equal and without me being able to get my hands on the truck for further inspection, what are the odds that those three changes - synthetic oil, a catch can, and the new valve cover - will help the oil consumption? Could this be an AFM issue that needs to be addressed via a tune/the Range plug-in? Am I maybe looking at a bad gasket somewhere that's seeping/leaking oil?
Thanks in advance for your collective two cents - as a long-time GM driver and relative newb to this platform, it's much appreciated.
