Thread: to rebuild or not to rebuild

i have a lot of blow back, should i rebuild or put in a new motor. master rebuild kit is 700, new motor is 1600? thouhgts and opinions please...

A few questions to consider..What is the warranty status on a new or rebuilt motor, and how confident are you on your own rebuild? Sometimes if you're worried about loss of use it's a good idea to pick up a used motor, throw that on the bench to rebuild while you're still driving around on your current set up. I'm personally a fan of Jasper rebuilds 3 year, 100,000mi warranty.

The rebuild can be done in 3 days no doubt. However, the machine shop you choose has a lot to do with how long you will be down. Most machine shops I have delt with can get the job done in ~ 1 week. I know some people think they can get away with honing the cylinders and throw a kit at it, that usually ends in diaaster and they end up spending twice as much trying to save $300.
At a minimum you will want the block bored out to the next size/ mains checked for alignment/decked and dipped. Rods reconditioned/head reconditioned/crank checked and ground to next size if required.
You only want to do this once so spend the extra and do it right.

It is a much. much better system.
