Reply to "New heads, new intake, new rockers, new pushrods - Very noisy valves and very little oil through pushrods"

Not enough oil.

There may be (should be) oil restrictors installed in the block for high performance use. They get installed in the oil passages that come from the bottom of the engine.

I haven't done them in a while but the oil passages are either 1/4" or 5/16". Might even be 3/8". Can't exactly remember right now?

Those are over generous and the restrictors, which are allen socket set screws have something like a .100" hole drilled in them.

In addition for "high performance use" it is recommended that lifter sleeves be installed in the block which further reduce oil to the valve train.

In the original Boss 351 with solid lifters, Ford used a special lifter, referred to as the Johnson lifter, with a much smaller oil orifice to reduce the oil to the top end.

There are ALSO oil restrictor push rods with smaller oil passages as well. Having an engine with all of these unknowns is an issue.

Having a "builder" who doesn't know WTF I'm talking about is also a BIG issue.

You use them even if you use lifter sleeves (which I don't see in your video) and the Johnson small orifice solid lifters, so exactly how much oil should get to the valve train, I'm not sure?

Now since I don't use them, I don't know what you do with a hydraulic roller lifter but I'm thinking that oil restrictors down below may be wrong to do with any hydraulic lifter because that design relies on a quantity of oil to operate properly?

So there could in fact be a contradiction here with a hydraulic lifter cam intended for high performance use in a Cleveland block?

You are getting nothing to the rocker arms? You need to talk to the cam tech guy but I wouldn't count on them to know what a Cleveland needs, but they should know the amount of oil the lifter needs.

Your engine needs serious help. There are specific items of knowledge that are necessary for building a Cleveland. Some things cross over from the Chevys but many don't.

The problem with dealing with Chevy guys is they think they know everything about everything which is the farthest thing from the truth.

Unfortunately they don't even know what they don't know.
