I have a 2001 6.0L engine that I disassembled and I wanted to know if I could reuse the main bolts. This block had about 7800 miles on it. Any comments.

 

Stock bolts are not meant to be reused. You have the entire block dissassembled, why not spend the money for ARP main bolts and not worry about having to take the block apart down the road.

 

Ive heard that you can and you cant. I have and didnt have any problems, but I would do like I did this last time..... buy a set of main studs. Stronger fastener and use them many times over

 

The stock main cap bolts can be reused. It would be best to replace them if you have the money with some new GM bolts or ARP mainstuds.

The side bolts can be reused as well but you need to apply some thread sealer to the threads as the bolts come with a sealer from the factory.
