I'm about to check my spark plugs and do the compression test soon. Is there a recommendation on whether or not to do a wet or dry compression test on all of the cylinders?
Also, is a leak down test worth doing, to check for issues with valves and such? I've kinda done some slight research, but there's a few varying methods people add to doing leak down tests, like turning the engine and whatnot.
I have not yet replaced anything, and the in-line PCV valve I had added to my "out" routing to the catch can, probably just slowed/reduced the amount of oil blow-by I got. I've since thrown on GM P/N #12594779, which is a rubber PCV breather hose for the LS2 engines. I hate the stupid quick-disconnect crap with the plastic hose that the LS3's came with..
I'll probably double check the intake manifold for oil once I get my car smogged and throw back on my Airaid modular intake tube. I recently snapped off the plastic PCV nipple on the stock LS3 intake manifold, which recirculates from the engine valley cover breather port. To fix this, I stuck a 3/16" plastic hose barb union fitting into the intake manifold PCV nipple port, snugged it, and left a platform for the rest of the snapped portion of the PCV nipple to snag onto. I proceeded to put JB weld around that and the cracked area, which has cured and holds the new breather hose well.
The repaired PCV port is now smaller for the inner diameter (ID), due to the repair obviously, but I doubt that's gonna reduce the amount of oil blow-by by any, if at all... I'll run intake valve cleaner through the intake tube once I finish my smog and re-install my oil catch can...
