I've got a cute little bone stock '97 dually, thought I'd stop in and say hi. :lol:Bought it last november with a fresh head gasket and 242k on the clock. Never got the cooling system clean and it would still make coolant once in a while (oil to coolant, never the other way around). 5 speed NV4500 with a "fixed" nut failed a week later.put in a rebuild NV4500 and dual disk south bend... that lasted 18,000 miles - broke teeth on 5th. input shaft was slightly twisted.Spent a week putting an Eaton RTOO9513 in it. The .68 top gear is like swapping my 4.10s for 3.55s, I love it. Lost my transfer case though of course. I've got a divorced NP205 to put in but it needs a rebuild and bigger yokes, etc...which brings me to Haloween time this year and the block cracking. Scored a complete 24v from a school bus for $440. Swapped over my P-pump junk and it's back up and running. Took about a month. I do crazy projects, what can I say?

well that sucks but at least you found the culprit!!:banghead:

Welcome to the site.

Figured I'd throw an update here - tracked down the backordered flywheel ring gear through a friend in the business, got it replaced, and got my pressure plate springs upgraded from ~2600# clamping force to ~3400#. No more RPM flare in top gears!Took a week between waiting for parts and putting it back together. Made a 250 mile round trip Monday.Just replaced a bad pressure switch and pressure gauge on my air compressor last night, and I'll be putting about 1000 miles on this weekend back and forth to Dayton OH.Cruise is still out, boost control still is sketchy, but no more leaks as of this morning with some additional tightening of everything, and she's nearly tip top again as I approach the new motor's first oil change!

Borrowed my buddy's common rail. I'd intended to just borrow his little trailer that my truck is on for an errand I was running for him, but my 12v block had other ideas at 268,000 miles.

Turnabout last night due to a broken #4 injector line on his hog. His replacement line was only $23! Hate him a little for that....
