Welcome! This is a good guide to get you started. I'd add to it by suggesting braided steel oil cooler lines, the crimped Rubber lines leak and burst turning a 6.5 into a boat anchor real quick

I get about a year out of no name batteries in northern Alberta. Seems like they last just long enough to be outside of warranty. 2-3 with interstate, I believe theirs are 5 year pro rated for the new ones. My last fix was to put two large tractor batteries (group 4-D's) in the box in front...

I imagine you would need to rig the manual lever position switch from the 4l80 onto the side of the 6l90 if you want the stock instrument panel (on a 95-98 dash) to show the gear selection (P/R/N/D) and have the reverse lights light up in R...

Looks great! Anyone nearby who can galvanize that frame and keep er shiny?

Would an OBDII PCM need re-flashed to have a manual transmission? Does the stock pigtail that would go into the 4L80 just plug into the PCS wiring for easy plug and play? The harness that you sell Quadstar, is it the same as what PCS manufactures for distributors, or do you modify it based on...

I did some spot checks on Chrome, new Edge and Internet Explorer, some links in 6.5 Diesel Technical Library work when clicked while others return "www.thetruckstop.us is currently unable to handle this request." on chrome/newedge and "HTTP 500 Internal Server Error" on IE. I'm on windows 10...

If there's any more info your guy could share that would be great; pictures, wiring diagrams, dimensioned sketches, custom fab or bolt on products used, diesel unique shift programs; that would be great! I know there's a few people interested in this upgrade, myself included!

An AC evaporator looks like it has the same fin design as an water-air intercooler, in cutaway photos both cores look similar to a car radiator but with heavier wall thickness for the liquid. I doubt they would be different metals. An of air-water intercooler could be pressure tested to the...

Just read some interesting papers from India on air-air intercooling, water-air intercooling, and refrigerant-air intercooling. Under high engine RPM and moderate load, increase in air density across the heat exchangers was ~43%, ~75%, and ~160% respectively. The effectiveness of the air and...

Mine. '08 block. Problem is nobody checks for cracks inside the crankcase until their next rebuild so nobody can prove beyond reasonable doubt that it was over torquing of studs that caused the web stress crack(s) and not engine imbalance or harmonic balancer neglect.

The link to DSG's main stud girdle torque instructions went stale. Thanks to wayback machine, it's still on the internet.

Time to sue DSG! "These ASSHATS" as Gale Banks would call em. Who knows how many people screwed their blocks trying to make them stronger because of inept product engineering. The shortest compressed height for a hollow hydraulic cylinder I could find was 51mm (2.008") which is still longer...

-36° where I am RN. No moisture issues here when everything is already frozen 😂

My '08 optimizer came with diamond stamped precups and the navistar logo in the valley. Cant speak for other optimizers.

Hell, it's about time!

I have the AutoEnginuity scan tool which is the one that Leroy sells. It has the time set command and can read out the actual and desired parameters. I have successfully initiated a time set command and got the actual and desired readouts on my '97 with this tool. I can't speak for the...

And what scan tool?

Yup that's where I got mine from last month. Didn't know they had more, when I chatted with them in August Mark said they got two 60° motors from the acquisition and the other was already spoken for so I thought I got the last one.

*Correction they had the block since July 23'rd. They got the heads early July. Either way it's starting to drag out

Update! Precision Automotive in Grande Prairie wants me to not weld repair the crack because heat cycling the engine hardens the steel and it wears out bits on their machining equipment. They said I should tell them to go ahead and complete the machining without repairing the crack and run the...
