The reason i swapped lifters is my new motor has had a tic when warmed up since it was new.i tried different length pushrods and a couple new lifters to some affect.30k miles later i decided to just replace them all and it didn't really quiet down the ticking
I guess now I'll try the pushrod game again.
Possibly 5w-30 and 10w-40?
Maybe a high volume low pressure oil pump?
I had a conversation with
@Woodrow about his aftermarket cam being noisier than stock too. If i remember right most guys with a larger cam in their 4.0l have more valvetrain noise.
Any advise or suggestions on this would be great guys! I'll be reaching back out to russ pottenger and the friend with a machine shop who assembled the bottom end for ideas too.
