What Lifters..?

"Nickel"

S-Series Syco
So I've got a lifter tick. Stock engine. Question is what lifters to buy 850's or 875's? Or another option?
Did a search and got a few threads with conflicting info...

Re: What Lifters..?

I sweated over this issue quite a bit when I was rebuilding my motor a couple of years ago. My understanding is that the 875's have an inherently better design, but are louder. The 850's are basically a stock replacement, and that is what I went with. Unless you are going all out on your motor, I would use the 850's.

Up till now I had no reason (or desire) to open up the engine. I don't have any plans to mod anything internal. I don't want anymore noise than need be....so I guess 850's it is.

Thanks guys!

Re: What Lifters..?

My builder said that unless you're going all out just by stock replacements. Delphi? That's what I did, no issues. Looked it up. $160 for 12.

Take the covers off and check each valve to find the tick. Tighten that rocker just a tad. No luck? Maybe not a lifter. Try:

Get out a stethoscope and listen to each inj. I have one noisy one that could easily pass for a ticking lifter.

At the risk of getting shot, run some Lucas oil treatment through the motor first.:lol:

If any of the above actually works you've saved some bucks and a ton of work. Won't hurt to try.
