I finally got my newly built (ERA #801) on the road, with my freshly rebuild 427 sideoiler. Needless to say I was scratching my head and not a little disappointed when she kept burning
oil! At one point I went through 6 quarts of
oil in 100 miles. I've built a few 390's back in the day and never had any
oil burning problems. I turned to previous threads here about burning oil issues and the ones around the intake pulling in oil from the valley side seemed to be most relevant to what I was experiencing.
I have new Edelbrock heads with a Blue Thunder intake. I used the Edelbrock intake manifold gaskets. I had no problems with
antifreeze in the oil. But did have idle issues (hard to tell with the cam I have) and I could never get the mixture right. It always seemed to burn lean no matter how much I adjusted the mixture screws (Holley 4160, 750CFM).
This weekend I replaced the intake gaskets with the Fel pro 1247-S3 and used Motorcraft TA-31 sealant. I was unable to find the Victor Reinz gaskets. When I did pull the intake off, there was evidence of oil between the gasket and head side of the intake port.
Everything runs great now. No oil burning and idles better.
