I’m rebuilding a factory IDIT (201k miles) to replace the ailing 7.3n/a in my ‘92.
*Should I have the machinist balance the rotating assembly?*
Unless a problem comes to light most all the internals “look” good, except for two of the pistons which have a little deterioration of the top edge. After cleaning and ultrasound to check for cavitation the machinist will determine how much the block needs bored. He asked if I want to balance it when the new pistons, rings, etc come in. $400.
A little background on the machinist: he comes highly recommended by multiple parties; he has been doing this for decades and is very detail conscious; he’s always buried in work so he doesn’t need to recommend unnecessary stuff to get more work; he owns and has rebuilt IDI’s, but his primary business is gas race engines.
Recommendations?
All opinions welcome, but perhaps specify if you 1) have personal experience with multiple rebuilds, 2) have personal experience with one engine, 3) “know someone who...” 4) are blowing hot air
