The valve cover gasket trick that saves me every time now
I got tired of fighting with valve cover gaskets that always seemed to leak again after a few months. No matter how clean I got the surfaces or how tight I torqued the bolts, they'd seep oil around the corners. Then a guy at the NAPA in Columbus told me to try using a thin bead of ultra black right in the corners where the timing cover meets the head. I did that on a 2007 Silverado I was working on and it's been bone dry for over 6 months now. The trick is you let the gasket sit in the cover groove with a little rtv in those trouble spots before you even put it on the engine. Has anyone else dealt with those pesky corner leaks on the 4.8 or 5.3?

Used to think RTV was overkill and just a way to sell more tubes of silicone. Then I tried it on a stubborn 4.8 corner leak and it's been dry for almost a year now. Hard to argue with results like that.

RTV beats a soaked gasket every time @ivan_harris, that corner trick saved my old Ranger too.

Man I feel this so hard, I swear my Silverado leaks oil just to SPITE me when I try to fix it. I've never tried the bead trick in the corners though, that's brilliant and I'm probably gonna steal it because my luck with gaskets is basically zero.
