Well, driving down to the family X-mas party, rolling through the hills, the truck starts to sputter, and dies a few seconds later. Look at my gauges once she's off the highway, and the thing is overheated, bottoming out the needle... Never had that happen before. BTW, this is on the 98 12V 5-spd 3500. So I run to town with my mothers Jeep I managed to snag while she was at the party, ran to the parts store and grab a new thermostat. Put that in, let the engine cool, fire it up, and it runs like crap. Now, there's no oil leaking at this point, but its definitely missing (in the #5 cylinder apparently), and I still have oil pressure according to my gauge. So I have it towed to D&W diesel in Buffalo. Well, they finally got to looking at it today (I dropped it off last Monday), and told me there is NO coolant flow, that the #5 cylinder isn't firing (haven't pulled the injector yet) and there is a big oil leak under the passenger side (might have been the drivers side, can't recall I was too ******).

So... What could have happened here? The #5 cylinder might just be an injector, they have 300K miles on them, but the oil leak scares me big time. I'm hoping its just the turbo (cause I have a spare one of those kicking around). The coolant flow also seems odd. I just put a new thermostat in the thing, what else could be blocking the flow?

How screwed am I? I mean, I do have the 99 to haul my **** around, but the 97 is for sale (cleaned up, I don't want to drive it at all), and the 98 is DOA...

Any thoughts anyone?

Heres what happened to my 97's #5 cylinder. https://www.dieseltruckresource.com/...d.php?t=225749 hopefully that's not the case with yours a reman P pump is $1,200 -$1,400, I got a used one for $450. I can't offer anything on the other problems, they don't even sound related. A compression test might tell you something about the miss and if the head gasket is blown. Also pressurizing the cooling system may help find a HG leak.

Whats the oil level? How did they determine that there is no coolant flow? Only thing that comes to mind is throwing a rod through the block, but that should be immediately obvious.

Yeah, its not a rod, they, and I would have noticed that. When I last had the truck, there was NO oil leak, and the level was in the safe zone on the dipstick, however, with them now claiming a big oil leak, its anyones guess as to the oil level. I don't think its a HG, as the head is studded and O-Ringed, and the engine itself only sees 35-40lbs of boost MAX. The coolant flow is pretty obvious, both hoses are cold, and the engine overheats...

I know this is a long shot, but maybe the water pump impeller shaft is broken. BTW, I've never had a water pump last 300k.

I would say broken impeller. But is the 5th cylinder thing related?
Hard to say.
Ive experienced a broken impeller which overheated the engine.
Which boiled the oil and ruined the bearings and broke a rod and shot thru block. On a JD motor.

98 is fine now... Bad water pump. #5 injector was bad, stuck closed in the 98 I guess. But, I swapped injectors with the 97 to see if it helped, and when I drove the 97 the #5 injector stuck OPEN, and then burned a hole in the #5 piston. Its now in the classifieds.

Need, man you just have the worst freaking luck.......

Wish I had the spare $$ I would like a spare NV4500 and TC.....

Need95-00CTD

Haha, yeah, tell me about it Pat... Been a while. How you been?
