Shelby alum block, 428 crank, Edelbrock heads, Shelby roller tip rockers.
After 500 mi break-in, This engine has developed some problems which may or may not be related:
1. Left bank plugs wet with
oil,
oil smoke out the left side pipe.
(running no restrictors to rockers), rt side ok.
2. rear main seal leaking .
3. Running webers, only vent is rear of intake manifold, none on valve covers.
I.m thinking I'm getting too much
oil up in the heads.
Thoughts ?
