Big Block 455, 60 Over. Have Had A Problem With Oil Collecting In The Edelbrock Performer Intake Runners Which Causes Engine To Smoke. Tried Different Gaskets,( I Should Buy Stock In Fel Pro) Adhesives Etc. Also Tried A Cast Iron Manifold.
Started Out With C Heads That Were Ported, Changed To A Set Of G Heads Not Ported, Same Problem. I HAVE RULED OUT THE PCV.
Need Help ! Anybody Out There Ever Have A Similar Problem Or Have Any Ideas.

 

i think i read its best to use the fel pro gasket when using the performer intake

i believe i read it on summitracing.com in the description of the intake

 

I Used Mr. Gasket # 404 (recomended By Edelbrock) Numerous Times With Different Adhesives. Also Found On The Mr. Gasket Web Site Under Installation Tips To Use The Valley Pan Gasket Together With The # 404 Gaskets. Problem Still Persists

 

Worn valve guides? I know you said two differrent sets of heads but that is what first came to mind.

 

I would look at intake for possible crack and if there are any threaded holes in the manifold for plugs make sure they are there on floor under carb and underside. Thick paper gasket from MR Gasket should seal......

 

Both sets of heads are rebuilt, new guides etc.

Thanks Jim P
