HI i'm new to this forum and I came here for some help. I'll give you some background. So I have always been a Mopar guy and last year I bought a 74 roadrunner 318 auto red with white stripes. When I was a teenager me and my dad restored a 70 Charger R/T and stupidly I sold it. So with dad getting older I wanted to do a project with him again. The body of the Roadrunner is excellent but the motor was acting up so bought it home and decided to rebuild the engine and replace the 2bbl. with a 4bbl. So broke down the engine had it bored 0.30 over, KB167 pistons, compXE cam, new lifters, heads reworked, Melling high volume oil pump and Edelbrock aluminum intake with 600 holley. So now the problem. When first fired it runs good sounds good and after a few minutes is becomes a smoke machine and uses oil. I pulled the intake off and there is oil puddled on top of every valve so I replaced the gaskets thinking they were leaking. I restarted the car same thing. So I then got a cast iron 70 intake from a 340 and tried that same thing again. So as a last resort I put the 2bbl. back on same thing so now I'm at a dead end I have never seen an issue like this. The heads have new seals so I don't think that's the issue but now I'm questioning everything. Any help would be appreciated.
