Yeah- some water beat up the differentials a tiny bit but nothing at all to worry over. As mentioned- make sure the breathers are cleaned up. & if you offroad half as much as that is rig deserves it, extend the breather hoses way up high. In hmmwvs they tie the two together then use a small...

Depends if it is a short circuit or a battery draining component with or without key on. Basically measure amperage pulling from battery. Leave the meter in place and pull one fuse at a time. When amps drop- that That will id the circuit. Finding a short circuit- that isn’t fun. You...

Yup. Some bone head told AM General & the military that 230,240f is ok for these engines and they blow through them like candy because of it. Meanwhile everyone else that know 220f means PULL OVER NOW & let it cool off- the engines make it a long life. There is other things to look at &...

I can’t remember reading anywhere that showed the Dalton date code pattern. Maybe some calls or emails sent off could get results?

The 4l80e has minor changes year by year. DEFINITELY have yours rebuilt.

Can you take a picture of where the date code usually is?

I don’t know chimneys, but wouldn’t it be better to use two 45° fittings?

Remember a dab of anti-seize on the threads. In COLD weather a second cycle of the key is needed or the override switch. But the couple seconds are worth it. Hope you ordered from an authorized dealer. Lots of cko junk out there.

I used to recommend the bosch that were 80034 duraterms (the number changed since then to a longer one but device was same). Then one failed, broke off and destroyed my piston. The plugs were not 10,000 miles use in an optimizer engine with all the maintenance done one could think of. You...

Plug in the block heater and see if that solves it or lessens the time it is smoking. If so, that will point towards the glow plugs not warming it enough. Is there any correlation of engine coolant temperature and smoke? Does the smoke smell like diesel fuel or like coolant? If the heater...

To be clear on my last post: the r-7 stuff WILL FAIL in time. Thats why I never tried it. Use the gm ones as they are super cheap & easy to swap on the injectors, then when you are done swapping around injectors and settle on a set, the original Mercedes Benz injector hose that is 1/8” is r9...

Without the signature line filled out, I can’t recall what you have or haven’t done for lift pump, fuel pressure gauge, clear line. Besides this site there are more that myself and others go to and try helping various people. You should have a 6.2 with mechanical lift pump factory that feeds a...

@MrMarty51 I would tend to think your 4.10 gears are having impact on the hiway mpg. Did you get a lot better mpg before part of this build?

AND… some of us who really want cold air blowing on us on one of the 250 hot days of the year here, learned the already mediocre a/c system somehow gets worse with the cup in the way of the vent. Idk if I can actually drive a gmt400 without a super big gulp on the seat between my legs…

100% exactly what Doug said. That isn’t a theory of maybe- that is a CONSTANT repeating story. A pump or steering box should be no big deal- but they are for some reason.

Meh, I say run it and have Jerry Reed playing loud as you go! 😂 I had a few single wheel 1 ton trucks, from 77-99 model years. The duals really help hold the trailer straight in crosswinds and slick roads. There are hitch devices now to fight those problems. The power the trucks have now...

Before buying any headlights- go to a YouTube channel called “Headlight Revolution”. They do actual comparison testing on all different headlights. There are MANY types sold that although have better advertised numbers do horrible. Some that are even worse than just stock headlights! Adding...

Excellent job doing it now instead of waiting. That saved a LOT of annoying labor.

They are hard to find. there are two versions of it but idk which is which, iirc they are numbered differently. Note the 4 bolts for the thermostat housing. One style has a bypass (block off) thermostat and the other does not. For obvious reasons the block off is the one everyone preferred...
