Default Replaced them lifters and car sounds like a deisle truck

Are the push rods aolid or hollow with holes top and bottom for hydraulic lifters?

I am the one with the strange lifters that replaced with the modern type and new push rods, the push rods i have are solid and there is no oil getting to the valves !

Sounds like a mac truck.

Ithink you better get some with holes. That's what they had. Did you change the rockers or cam or shafts? You might have to go longer or shorter or standard.

Can you get a quality shot of the rocker arm and pushrod?

The valve lash is adjusted by pushrod length on a hydraulic. Did the tech go through the sequence?

I changed the lifters and push rods, the ones in it where weird, solid kinda with diferent lenghts on the push rods, maybee a aftermaket performance thing of the era, look at my post on lifters, solid or hydraulic.

The push rods in it where solid with a none adjustable rocker arm, and a strange lifter that only had about a 1-2 thousands play in them, all push rods where different lenghts.

I thought the hydraulic lifters would automatically set at 0 lash once the roker arm was torqued at 45 lbs.

No. The length of the pusrod is critical and is how that adjusment is realized.

There is no oil supply coming from the rocker arm shafts?

The oil supply comes through one of the actual rocker stands on either bank. It then feeds each individual rocker through the rocker shaft(s).

You may have the rocker arm assemblies assembled incorrectly. Did the tech disassemble them for any reason?

One may use drilled pushrods to increase flow but this is very unusual.

Study your lube guide illustration again.

When I rebuilt my motor (only time I ever did an FE so a novice) I spent a fair amount of time cleaning the entire rocker assembly and making sure the oil flow from the motor to it was clear and made sense. There are also diagrams both on-line and in manuals showing the oil flow. In other words if you study the assembly, you can see how it is designed to flow oil and also decide if it is possible to assemble it wrong.

I also recall there were either 2 or 3 different pushrod lengths.
