669dennis Dec 8th, 01, 03:39 PM I have a set of crane gold roller rockers,and noticed that there is hardly any oil in the roller rockers and valve train,I took the valve cover off and revved the motor and didnt get much oil squirting out.Like on stock rockers,the reason I ask this is because I`m getting a popping out of carb when I rev it up above 3000rpm .My thought was the push rod is not releaseing oil,there for lifters are staying pumped up and possible keeping valve open,what do you think?

Before I had rebuilt my 350, I had put it in right out of the junkyard, and whenever i got on it and the secondaries opened, it gave a rapid pop through the carb. Sounded real neat, but it turned out the cam was flat and the exhaust valves were not opening, allowing the 'explosion' back through the intake valve. You might also have a valve not closing due to a bad valve spring??? I'd sure do a compression test if you haven't already. Thats a basic, first step that can eliminate a lot of things right off. ------------------ 76 Camaro/mild 350 .030/M21/Z28 body parts/lotsa other goodies 669dennis Dec 9th, 01, 02:30 PM <BLOCKQUOTE>quote:</font><HR>Originally posted by XK1: A compression test would tell you for sure about that.
