Leaking valve covers

[Dr.drivability]

I've tried everything. I can't get these GN1 valve cover breathers to stop leaking.I've got the turn ups and everything. Please help. My garage floor is a mess!! Dave

try 2 stock felpros glued together with the red rtv, then glue them with the rtv to the top of the valve cover make sure they're lined up right. i tried this on my ta covers and it finally worked after trying everything except the rubber and the expensive gasket. so far so good just snug it after you let it sit over night on the head then snug lightly again the next day. thats what worked for me, keep them in check though.

Harleys and Turbo Buicks, they always let you know when they need oil.
