> Refurbish hydraulic lifters with new springs?

I have a webcam hydraulic cam and lifters in my 2.0 type IV, I am going to refurbish the lifters and figured I would replace the internals of the lifters while I was in there.

The purpose would be to squeeze more life out of the lifters before I have to crack the case open (at which point in time I will replace the cam and lifters with solid versions). I will replace only the springs and keep the two pieces of the body and the original ball check valve.

Does anyone have any advice on this? I am going to clean up the old lifters regardless since I suspect they are not filling correctly due to valvetrain noise, however I'm not sure that replacing the internals would be appropriate? It should avoid the issue with having the lifter surfaces and cam break in together by keeping the original surfaces.

I've also considered the possibility of keeping only the part of the original lifter that mates with the cam and replacing the internals and the other part of the body. However I believe due to the mating tolerances in the manufacturing of lifters that this might be a bad move.

Thanks for any help.

If this is all based on valve train noise, have you adjusted the lifters to spec?

I've got hydro lifters in mine and they can be noisy for several minutes if the engine hasn't been run for a while. Different oil weights can affect how long it takes for them to 'pump up', or so I've been told.

I've adjusted them to spec, and experimented with different amounts of turns in. Currently at 2 turns in.

The noise is there regardless of temperature and how long the engine has been running. Goes away above 3000 rpm though no matter what temperature the oil is.
