crack lines in valley cover - would you guys use this?
I bought this off of a board member and was a little surprised when I opened it up. I don't think valley covers "wear" so I didn't really push the condition of the part... however now I am wishing I would have asked more questions. It looks like there are little crack lines over parts of the surface. Would you guys use this LS6 valley cover? Is this normal?
Thanks, -Dave

I am doing a turbo setup and am wondering if presurizing the engine block (from blow-by) will cause an issue. I don't want any crap falling down off of the valley cover into the oil pan if it does to start to come apart.
I think the valley cover does seal the top of the block, helping to maintain vacuum, doesn't it?
Thanks for the input though... I am going to take another good look at the valley cover tonight to see if those lines are casting marks.

I have a forged HPE shortblock and I'm not up and running yet... I'm going to be PISSED if I need a rebuild on a brand new engine!

yes it does, to seal the engine for the PVC system
