12.7 Series 60- Issues after rebuild

You really need a dyno and a blowby test at a real detroit shop. They can give you a true health report on that engine.

 

That's a good place to start. If I was going to have my engine rebuilt it would be done by detroit diesel, or buy a factory rebuilt and swap them. Too much room for error to trust anybody I wasnt certain of.

 

Ya, it sucks to be led astray, watching the $100's fly out of your wallet and for no return is worse. Best of luck with it, start at the basics and make sure you have a good detroit shop to sort it for you.

 

A full inframe? Where? What's included?
Did you do a dyno to see if its needed?

 

Hers the upgraded cover and bracket I mentioned. 4 extra bolts on top, supposed to fix or avoid the problem of holes wallowing out and bolts breaking. Looks like maybe just the inner cover is different.

 

Probably well worth the wait. He probably wants to make sure the front gear train gets inspected good, and the cover is sealed up properly. It’s a lot of Labor. Might need some new rubber bushings/steel sleeves grommets for the oil pan bolt holes. They can always be changed later, one at a time, if it leaks. Main thing is they inspect everything. Gear timing marks, bullgear and lash setting. Make sure the numbered piston rods are in the right place, thrust washers are installed right and have proper clearances. Whatever else they can check while it’s off. What about the vibration? Is it real bad at idle. Does it ever go away? Are the new fuel lines tight? Mine hasn’t shuttered in a while. Still don’t know what’s wrong. I’m thinking maybe because I had the injector calibrations set differently than they were supposed to be set. I wonder if they never set yours at all.
