Yeah, I put a slightly leaner Edelbrock 600 carb back on and I think I am going to replace the intake gaskets tonight and put it back together. That crack in the gasket mayb e just enough to suck oil to the extent of the consumption I have, especially when the vacuum pulls it into the exhaust when I back off of the throttle.

I may rid of the cam lube and replace with Valvoline VR1 20w50, just to see what will happen. It wouldnt hurt anything and a little heavier weight is not going to sap that much power. Addtionally, it has plenty of zinc in it.



The thicker viscosity oil will definitely slow down the usage.

I am too having the same issue again now on my duster which I just fired up the other day. After about 1.5 hours of running it was down 1 quart and today I noticed some smoke so I think this intake is gonna need some TLC too. It is also leaking at the rear because I could only fit RTV there and no cork gasket. Guess I didn't get enough RTV. I am about to give it up as I can't seem to win with these cars.
