LNF Oil Leak


Goblin Guru
I just happened to notice that oil was leaking down the side of the cylinder head and collecting down by the oil filter. It's nothing major and not enough to even drip on the floor, but I find it to be annoying. After a bit of research, it looks like the leak comes from the camshaft cap which is where the high pressure fuel pump is installed. The pattern of sealant that GM used when putting the cap on makes it prone to leaks. There is a TSB that basically updates how you apply sealant so that it won't leak.

This only applies to the LNF motors. Keep in mind that yours may or may not be leaking. I just wanted to throw this out there in case anybody else has noticed this.
