was wondering what you guys think of this... took off my intake for some cleaning and saw this. lots of oil on the head and on the intake gasket. would a catch can fix this? its a 06 lq4 317 heads untouched other than a .030 mill. 228r cam 110 lsa nnbs intake this is on a 08 rcsb sierra. thanks

 

What you're seeing is pretty common. A catch can would probably help some what.

 

Thats not that bad actually. I've seen worse on bone stock 5.3 and 5.7 engines.

A catch can would definitely help, but not keep all of it out. I can usually fill up half a SOLO cup every 5-6k miles.
