piston replacement

Fostang · 02-21-2002, 11:37 AM

Hi there everyone. I'm trying to figure out if this machine shop is trying to screw with me and charge me an additional 250 for rebalancing the engine when I replace the pistons? Do I or don't I need to do this? Thanks

Depends. Stock replacement pistons in a stock engine should be okay, but there is no guarantee. If the rest of the engine is balanced, then you would be wise to balance the pistons.

I always have the rotating assembly balanced when it's for an engine that is ever going to see more than 4000 rpm's, but that's just me.

Take care,
-Chris
