Valve cover baffle
Hello All,
I have a 1980 L48 that has midly ugraded top end and I just upgraded to roller rockers but found that my stock aluminum valve covers no longer worked with the baffles. I got rid of the baffle but after a 100 miles I burned alot of oil and can see oil on spark plugs. I'm assuming I'm sucking that oil back into the carb through the vent and PCV.
Does anyone have a work around or suggestions on what I can add to keep that oil in rocker valley versus having it sucked through PCV valve?
TIA

Thanks. I tried to change valve covers previously but had a hard time getting the taller valve cover to fit on passenger side becuase there is a arm that supports the AC compressor that attaches to bolt on intake manifold and there isn't much clearence for taller cover. Has anyone found a taller cover that will work on L48 with the compressor support arm?

Before switching over to a Sanden compressor. I once had taller valve covers. I just deleted that brace.
I never had any issues with it removed.
then I went with the covers I still run today. And the brace fit. So I put it back on but it never made any difference.
Then I finally seen the light. And converted over to a Sanden compressor. And it's mounts do not have such a brace.

Tall Valve Covers look soooooo much better anyway. Kind of Bad-***.
And they add 50 horse.
The use of VC spacers or doubling the gasket, doubles the chance for a leak in a prone to leak area.
Baffles are a must. Oil Drippers is a plus for those rockers.
