Thanks for the advice! So I parted out the J 6.2 with 60,000 miles. Got quite a bit of spare parts off of it. Should I get the crank? Worth the effort? Now I got the 6.5 on the chopping block. Gonna remove all the electronics and see if I can get it running on a DB2 and Hx35w. I am just...

Injector pop pressure tester showed up. Can not wait to use it! Valve Spring compression tool showed up too! Not bad for only $20 eBay. Machine shop called and told me the head has cracks between the valves where the rag was. I went over right away. They got the rag out, jetted the head and...

Your welcome!

Could be a bad injector! Waiting for the pop pressure tester to find out! No worries! I fix everything! 2insane makes it all better!!! Up next is a 60k J code with nothing wrong with it... Lol! Except for the shop rag that got sucked in the intake! Off with the head already and sent into the...

So everything was going great! All of a sudden she started blowing large amounts of white smoke. Smells like unburnt fuel. Ordered a rebuilt injection pump 4544 from Pensacola Diesel, Inc and ordered injector pop pressure tester and valve compression tool. This build is on hold. Starting fresh...

Yes the harmonic balancer can go out of round. I have 2 of them in my shop right now. I’ll get pics for ya. Your buddy going to do the dual alternator set up? Here’s one of my 6.2’s with only 60k... Here’s my 6.5 with 214k... Note the rubber is pushing out where some rubber is sucked in...

I have 5 injection pumps and was wondering if anyone has a list of all the DB2 injection pump years with numbers? Thanks!

Wow! Yea what is that like 4” of more drop from the girdle? I think you should give Kennedy diesel a call. I think he would know.

Ok will do!

On the motor stand with the 130 gpm water pump, 195 single thermostat temperature testing with the shops laser thermometer gun shows that the motor definitely gets at least 30 degrees hotter before the thermostat housing which tells me a lower thermostat is a must have! The hottest parts on the...

Yesterday afternoon I lifted each side of the Blazer with the Hi lift Jack so I could finish drilling the last two bolt holes for the Motor Crossmember because my drill is too long to get a straight hole. I made darn sure I kept my body away from anything that would kill me if the Jack fell out...

Things have been busy at the house and work the last few days. I finally got the ORD engine crossmember brace on. It was a PITA to install because my frame was not 100% straight so the bolt holes did not line up that great. I had to bend the frame to get it to line up. Not much, just a few MM...

Crucial info MUST READ! About 9 years ago I remember reading about a guy in West Jordan Utah buying up the last of the 6.2 Banks Sidewinder Turbo rebuild kits. I think I might have met him on one of my Moab trips. Anyhow, I found his posting on EBay. I bought his second to last one just in...

Your welcome! I am not afraid to post up my failures and problems that arrive. It is all part of the learning process for me and the reader. I just ordered a 180 degree thermostat and will try that. I currently am using Red Dex Cool to help prevent corrosion. This article explains exactly...

I randomly went to a guys house that owns a stock M1009 and looked at the motor bay. I am not happily convinced the 6.5 valve cover and Cdr location will suit my needs. I will replace the 6.2 valve cover and oil fill tube and use a civilian Cdr bracket. The motor misfires a little. I will turn...

I hooked up the radiator and did the 2nd coolant pressure test. Still leaking from the thermostat housing. Looks like I will need to get a new one or double up on the gasket. Kinda strange that the thermostat housing gauge reads 15 psi and the rear coolant plate gauge reads 11 psi. I am guessing...

I tried a series of different tensioner pulleys and could not find a good fit smaller pulley. So I decided to modify my own. I picked up this free pulley from a friend. It came off of a Subaru tensioner pulley. I used my die grinder and took off 2mm and then took off 1mm from the 6.5 aluminum...

Looking nice! Great find man! What are the grand plans besides maintenance?
