Aftermarket pushrods/ rockers

[TheAvidHobbyist]

Are there aftermarket pushrods androckers that give better oil delivery to stop the excessive wear we get with stock? Also heard something about replacement of oil pump "driveshaft" as they supposedly wear to the point of failing to drive oil pump. Any recomendations as to "upgrade" oil pump?

I don't think there are any problems with oil delivery on/in a 4L. take a valve cover of while the engine is running and watch and see how much oil is delivered up there.

upgrading an oil pump is not a simple job.

cheers

PS something I forgot to add, The pushrods are also solid, they do not flow any oil in them.
