can anyone rebuild my motor honestly

You dont have to. I would run it till you have a reason. Excessive blowby or mixing fluids

 

Are you more after work quality or warranty?

 

I doubt cat gets it done that cheap.

 

Milton cat....... there’s your warranty. You’ll spend $30K.

In New Hampshire a guy named Doug Burdick is a cat expert.....

 

Rods and mains, @ 1,000,000 for peace of mind? Not terribly expensive.

 

Waste of time.... the new way is run them till rebuild.

Everyone I trust with my engine work agrees on this......

 

When you rebuild it might want see about Pittsburgh Power.

 

Honestly engine work is not as big a deal as everyone thinks it is. 95% of it is following the proper service procedures in the manual and taking the time to make sure all the adjustments are correct during reassembly. I'd be more concerned about the cleanliness of the shop. I've been through some truck dealers where they've got engines opened up with all the shop doors wide open, dust blowing everywhere. There is really nothing special about a 6NZ Cat. They get rebuilt all the time just like every other engine on the market and Cat has all service literature available for 98% of everything they've ever built on their SIS web. A trained monkey could read the overhaul procedure and do it.

 

Here is a better video of explaining an overhaul on Caterpillar. No BS or claiming parts are specially made by him.
