If you get one of these it can really help identifying where the noise is coming from. Mark

Yep Yep and rain will come in but it is all normal. Mark

That sounds low down and not good. With a stethoscope I bet you will find that noise from the oil pan. It just stated doing that out of nowhere ? Mark Sorry about the problem.

The motors rebuild tag lists the rebuild as 2008 so if the block was good enough for a rebuild it would seem it would last for if t was to crack it would have happened in its first life. Sound reasonable? Mark

Just plain valve covers no markings at all. Can't see any diamonds but it is hard to see in the valley. Would not the block casting numbers tell what engine it is? Is it still possible it is a GEP motor? Block casting numbers h217 pass side rear of block 12555506 drivers side rear of block...

Thanks I thought it was all the earlier 6.5s and she runs like a champ and only has 17K on her since the refit. I will look for the diamonds and thanks again. Mark

Yes but I hope it is a late model version that does not have the cracking problem. Can the turbo setup be installed on this motor. No idea how one could drill out the oil passage inside the casting without putting metal in the block from the drilling. Mark

It's on the right side.

I thought I had a 6.2 in my truck but it is a 6.5 and from what I can tell it is the better block. Can someone please confirm? Was hoping for a GEP but oh well. Thank you. Mark h217 paass side 12555506 y00091097 020" on tag Tag says 03apr08 The above is the polymer coating that came...

Only time I do it is when the outside air is below 45 other than that she always starts right up. Either the linkage is a tad stiff or the high idle solenoid is not pushing like it should. Mark

No no the pic is just off the web for the heater. I have a 91 M998 in the four man setup. Below is a pic of mine. Mark

With mine on the cooler mornings now if I just go to start it after the wait light goes out it will start stumble and die but if I hit the pedal first it starts right up and stays on high idle. May by my linkage is a little stiff and the solenoid can't move it on its own. Mark

I plan on going with the X doors. The plan B doors just don't look as good in my opinion. Mark

I would hope you are aware of this but once the glow plug light goes off hit the gas pedal once and start the truck. This puts the engine on high idle and you should be good to go. One old trick I used to do was cycle the glow plugs then do it again before starting in the deep cold without a...

Dremels as already recommended will spin far faster than a drill but I don't know are what speeds the gauge will get damaged. At a reading of 4 thousand miles per hour it will take all night to get there LOL Mark

Very close.

There is a guy on a popular auction site that makes them and they look really nice. Good dollars but these are $$$ to begin with if you can find them. m998-nut is his handle. Mark

My 91 HMMWV. Just picked up mine from a buddy that put her together in CT. She came from the NJ National Guard. She was setup as a four man fiberglass maintenance truck. 17K on the clock since a 2005 refit. Had her painted in a Pingauer green to match my buddies Pinz and my M101A2 trailer that...

You sure don't want her to kick down at highway speeds so be careful with that. These things shift early as they make full torque at 2K. Oil pressure seems low but maybe the gauge is bad. Mine is the other way 60 to 70 PSI at idle and pegged 120+ off idle so my gauge is off. I am installing a...

Done...Thank you. Mark
