What did you do with your GMT400 today...or yesterday....

I found out this doodabber is a glow plug controller! never seen one like this animal before. part number on the sticker is 15575722. looking online it's a GM part. wonder how this thingamig works.

Don't know about that GP Controller but, earlier you'd asked about a DB2 rebuild company. You might try Classic Diesel Designs in Texas. I understand they're pushing some big plungers in their maxed out units. But, I'm sure they'll do what ever spec you want or is possible. They don't do DS4s. Internal pressure regulation won't allow for the output levels desired.

Yuppers- one of the first 6.2 -660 blocks.
That is what gm used for sensor connectivity before the weatherpack.
It’s probably good and somewhere out there a guy will be wanting to find a good used one. How you two meet up is the hard part- haha.

That’s a single stat non blockoff- but with the original rotation V-Belt system- balance flow is not a concern. If you are ok with v belt- stick with it. The harder part is finding exact lentils matching belts. Used to be we could buy them together in parts stores and you could see they matched because the words were cut as they made like 10 at a time then sliced them apart. There’s some YouTube videos showing them.

If you didn’t already- spray a little oil into each cylinder with wd40 can and straw to go through the precup via glowplug hole. This will help those rings that sat so long.
Then on your engine stand rig up the starter and let her rip through several revolutions. Once you know all the oil is out - compression test time.

Finally got around to installing / swapping out the return fuel lines on the injectors. To re-hash, I purchased the Delphi Injector installation kit and the return line hose failed several times on the 5 and 7 injectors. Failed as in split apart.

I noticed when replacing the upper intake that there were two bolt holes on the lower intake that weren't going to hold 17lbs torque so I had planned to do HeliCoil inserts to correct that issue. Well, It wasn't until I had finished the process that I realized that the M8 kit I had in the tool box was actually an M10 kit. I have a kit for M6 in the box too and, well, 'No Excuse Sir.' Heck, I didn't even have an M8 kit...Yup, face palm.

I have another lower intake only one of the ears is busted from someone not getting the return line out from under the back corner of #7 on a previous reinstallation.

I found these M10 x 1.5 - M8 x 1.25 serts / thread repair inserts by Patkil on the Jungle Site and will sort out the boo boo on Tuesday. I got them in two lengths, 15 and 25mm for the corners and the middle holes.

Bill offered to send me one of the few he has laying around but, with even crappy looking units going on E-Bay between $260 and $400 plus shipping, he could make some money off those. I'm just going to own this one. Another friend has offered to weld up the broken ear on the spare but, being between moves, his gear is spread out between two locations so that's on hold. So, in the meantime, I'll just deal with the repaired units...until my CDO (OCD with the letters in the right order) takes over reason and practicality.

I’m at a loss as to what you’re talking about here?

I F'd up my thread repair job and am using thread repair inserts to attempt a correction.

There should be tons of 6.5 lower intakes out there in salvage.
