Too much air pressure on valve cover breathers
I was thinking the ring gap was a little excessive too...if starting out fresh.
Most stock compression, OE setups run .016" top ring..... .019-.20" second.
Even if Forced Induction were an option on the table.....I think I would have ended up more around .020" top ring.....022" second ring.
I eliminated my pcv valve...and put a breather filter valve cover on both sides....no more oil leaks!!!!
