no oil at roller rockers
 

My buddy's 350 lost both ends of a pushrod and there is no oil coming out of any of the push-rods/ rockers. He revved it up to about 2000 without any oil coming out. It has about 30# at 2000, about 15 at idle. Any thoughts?

Not enough information.

Already running for X amount of time?

New build?

Any changes?

Street engine?

Race engine?

Cam and lifter type and brand?

Car was bought with rebuilt street engine with blower, about 2000 miles on it. No oil on either of the heads. Don't know what type of valve train it has. Going to pull the engine and see what is up. Will post when we get that far and ask what we should be looking for. Still open for advice. Thanks

Is that 30# oil pressure at 2000rpm if so you should have 60 to 80#
oil pressure. Looks like main brg too much clearance or they are bad.

Make sure the galley plugs are installed in back of the timing gear.

that and the by pass

Re: no oil at roller rockers
 

What bypass?

Re: no oil at roller rockers
 

By-pass on the oil filter adapter?

You also might want to check and see if the previous owner might have installed oil restricters in the lifter feed oil galleys at the back of the motor.

Hope you find your problem!

If the pushrod oil feed hole in the lifter isn't in the band of the lifter or doesn't have a groove machined from the band to the oil feed hole this could be your issue, sometimes the lifter bore clearance isn't enough if the feed hole isn't in the band. Just some more places to look...

It's not a Bowtie block, is it? Because with those, engine builders have been known to forget to reinstall the galley plug that feeds the cam tunnel, which causes seemingly unexplained, but repeated (until you figure it out) cam bearing and lifter failures, due to lack of oil. Obviously, if the camshaft isn't getting any oil, the pushrods and rocker arms won't, either.
