Customer Question

I just bought a marine 4.3 short block . The keepers that hold the roller lifters in place are different than my old block. Plastic verses individual metal on my old block. I am reusing the old lifters because the original engine only had 232 hours on it. Could this cause problems?

Hi there,No this will be fine. Plastic is just a cheap replacement.Let me know if you need anything further.
Customer: replied 2 years ago.
My question is this. Do the roller lifter keepers have to be matched to the lifter? Can you use old lifters with the new plastic keepers?
Expert:  Jeremy R. replied 2 years ago.
No they don't have to be matched with such low use.If they were 1000 hours old then I would tell you otherwise.But only 230 hours isn't enough to make any difference in the tolerances.
