I'd recommend an inframe. It's cheaper and faster and the block itself is probably not worn out enough, after the first million, to need any machine shop work.

if you talk to most machine shops they like out of frame,an if you have extra money it is better,they can align bore mains,an other machining to clean block nicely,plus you get rear main replaced,an can also check clutch an if needs replacing it's free labor since already removed

Run the oil samples every oil change. If it still runs fine and gets decent fuel mileage then run it for as long as you can. In the meantime i would locate the oil leak and repair it. Just make sure you're getting good fuel mileage. The difference between 6 mpg and 7 mpg is $12,000 aprrox. annually, based on 125,000 miles annually and Diesel @ 4.05/ gal.

had this talk with my mechanic.. looks to be cheaper to buy a raman. eng. from cummins than to do rebuild.. they way they price their parts is crazy.. they are definately proud of their product. the parts alone are like $20-21,000 for a complete and thorough rebuild. and i got quoted $25,000 for a reman installed out the door

I agree with Stonetrans if you were going to do a out frame rebuild it's cheaper and probably faster to get a crate motor from cummins and have it installed.

Most leaks don't automatically get fixed since they are usually in places that aren't even touched during an in-frame, so having leaks is not a reason alone to get one. High blow-by pressure is a good reason and is also probably the reason for the leaks. If the cost to do an in-frame plus the cost to fix the leaks is high enough, other options like out-of-frame or engine swap need to be considered.
