I dumped WAY too much ATF in my TH400 before I finally found the leak. The plug for the parking brake panel shaft had popped out. In fact, I rebuilt the transmission with my favorite Hughes kit and STILL had the leak 😢. I finally found it and hammered some copper tubing in the hole. Hasn't...

This is a 6.5 with a 6.2 IP but this is the level of smoke you should expect. https://photos.app.goo.gl/VVXyvRNMJYMkndBe7

The 6.2 shouldn't make any smoke at all once the glow plug cycle ends. If you had a mechanical problem I would expect it to get louder as you rev the engine. It doesn't. I feel that points towards an injection pump issue.

I had a throttle shaft seal issue that led me to attempt to rebuild my own IP. It should be possible. All of the adjustable pieces can be removed and reinstalled without changing the adjustments, or so I thought. This was a good running pump. I would not attempt to reseal a poorly running pump...

Seriously, the truck started with difficulty and ran. It knocked and made unhappy noises. Maybe has some misfires. It smoked gray at all speeds. My truck would would start after sitting overnight and die immediately when I tried to accelerate. I replaced the lift pump which made it better for 6...

I tried to reseal an injection pump and this was my result. Should've just done the throttle shaft seal.

Black RTV isn't a hack. It's what it's supposed to be. The sheet metal flanges on the valve cover are too thin to properly compress a cork gasket. They were never intended to be used with gaskets. The double ended bolts prevent you from retorquing once other hardware is attached. The same is...

I just got my new to me 6.5 started today. I had a questionable injection pump and it smoked and knocked terribly. I put a known good pump on it and it still had a knock that I isolated to cylinder 5 by cracking injector lines. By the time I isolated it,.the injector started firing correctly and...

If an injector line is leaking it won't make pressure to pop that injector. That would explain the roughness. Good luck getting a wrench on the bottom lines with the rest installed. They come off in pairs. Install and fully tighten two at a time. I forget the exact order.

The alternator adds to whatever voltage it senses. The first alternator has its negative terminal connected to its case, so bolting it to the engine, attaches it to ground. If we say ground is zero volts, the alternator adds 12 volts and that charges the first battery. The second alternator has...

The alternator with the red insulator on the stud is the isolated ground alternator. That one goes on the driver side. As for the vacuum pump orientation, you can rotate it and orient it whichever way you want. If it won't drop back onto the oil pump drive shaft, just bump the starter until it...

I was daily driving my truck. I had to pull the valve covers and remove the gaskets within 6 months.

Don't use gaskets. Use the ultra black silicone. If you use the cork valve cover gaskets you'll need to retorque them periodically and you can't do this because the fuel line clamps are in the way. To add insult to injury, when you try to take the nut off the stud is loose so you won't be able...

Please tell us you didn't put gaskets under the valve covers. It sounds like you did. For primary wiring it should comply with SAE J1128. Automotive wiring has a flexibility requirement, especially at low temperatures that other wiring doesn't need to comply with. Otherwise, there really isn't...
