toasted 6.2 l

[nickd]

Posted on the G today also....

Today was surely Friday the Thirteenth. On the way to pick up an m1102 trailer at Ft Mead, about 3 miles from the main gate, the engine started to really get loud, oil pressure was normal, it was cold out and the water temp was normal. Having no other choice, I ran it to the base to the Gov. Liq. yard where it finally died. Since there is no hole in the block and no leaking fluids, its a terminal case of internal damage most likely a spun main bearing. The engine locked up 90 miles from home. Luckily I was able to get a flat bed and the folks at GL allowed me to stay warm till the truck arrived.

So, selecting a replacement engine is the question. 6.2 replacement or upgrade to the 6.5 non turbo. I am leaning toward a reasonably priced 6.5 non turbo new in the crate. Will the 6.5 engine drop in and mate up to the existing transmission? If so, I may go that route. If I can find a reasonably priced new transmission with Park I may just change it out as there is a new transfer case already installed. Changing out the transmission now will put a new drive train under my butt.

Any suggestions?

Should have left it a GL, when it went for auction thay could have said "driven in"

get a turboed 6.2 from diesel depot. a lot cheaper than a 6.5 turbo with almost the same power and quiter and will fit right in without any modification to your trans and drive train. thats if you are in a tight budget. but if you got a lot of money go for a complete drive train swap with a 4bt motor and a 4l80e trans with a np242 4wd/2wd from predator. and you will have to move your gas tank, change your drive shaft and shifter.

I think I would probably upgrade if you think that is what you want in the long term. I think parts will only get harder to find. New 4L80Es seem super cheap IMO. Same with 6.5's. My thinking would be that there is alot of them around right now but they will only get harder to get once they are gone.

I'm thinking really hard about grabbing a 4L80E and 6.5 just to put on the shelf. Maybe we can do a grouop buy!

A 6.5 na will drop right in. I did it on mine.

Thanks for the replies, will go with the 6.5na and maybe the transmission swap. Its only money. THANK GOD IT'S NOT A LIVER!

The 4bt 3.9 will drop in with more room and way more power. its way more reliable and you will also get way better mpg like closer to 20 mpg depending on your driving habits.

And you will also kill resale value as a MV if you put in a civy motor.

1 Does he plan on selling it?
2 it will only ruin military collector value
3 in all cases vehicle value goes up
4 it strengthens the whole of the vehicle
5 way better mpg
6 person who is a cumins collector would buy it in a heart beat
7 people that don't even like humvees would be more interested in buying

A good example is take a jeep or a truck of any kind worth 3,000.00 normally. put a 4bt setup in and you will get at least 8-14 k I've seen it before. So to the right person he just added 5 to ten garand to the value.

Wow Nick, that really sucks! I always thought about stuff like that going bad when i'm far from home. So far it hasn't happened to me yet.
I have zero experience with 6.2/6.5 motor swaps, but if it were me in that situation i think I would go for the reasonably priced 6.5 non turbo new in the crate. Good luck with the project ....and the new matching trailer too. Is it tan?

Man, sorry to hear about that, Nick. Funny how a 6.2L will sometimes wait until you get to your destination to lock up. The engine in my CUCV locked up 20 miles from home right as I pulled up to the shop building where I was working on my deuce. Luckily, I was able to drive my deuce home.

A 6.5L with a 4L80E would be a good option if you want to keep your HMMWV "stock." You will need a new wiring harness plus have your driveshafts shortened and lengthened to accommodate for the longer drivetrain, amongst other things.
