Head gaskets... again...

Yeah what was the verdict? I'm gonna have the same problem soon, mine loses a bit of coolant. Ever since I got it hot towing hard one time.
 
no updates yet...I'm not sure what the outcome will be...the run to Michigan was hard enough last time and even a discounted redo may not make it worth the trip back up there...I don't even know what the offer would be...I'm actually a little afraid to find out... :eek:
 
I am no mechanic, but it sounds like it may not have been done correctly a year ago. You may have some legal recourse, if you choose to go that route. That is a lot of money to spend and not have it last.
 
Before you go to have the head gaskets replaced you may want to find someone local to reseal the injector cups. If they were not taken out, cleaned and resealed properly that could be your issue. Take the glow plugs out after running the engine and let it sit for a few hours. Then have someone spin the motor over while you look to see what cylinder is pumping antifreeze out. Once you locate that cylinder have those injector cups resealed and see if it solves the issue.
 
sorry...due to some forum software glitches this has not been showing up in the new posts when I click it...

In answer to some responses:

I can't say whether or not they were cleaned and resealed properly...but they were removed and resealed for sure...

I don't know how delicate these injectors are...but I do remember them dropping one, inspecting it and continuing on with the job...if it took a small ding making the seat(if there is one) out of round, could that cause it not to seal properly? I've never looked at one up close so I don't know the construction to know if that is even a possibility...
 
The injector cup is a round tube with a taper that it seals the waterjack on and o-ring on the top to seal the oil out. There are several things that will make them leak but the first and foremost is due to improper cleaning and installation. Since you've got a problem it's really a cheaper solution to try before ripping the heads off yet again. To replace them you need to remove the injector from the cylinder in question then remove the cup from the head. Once the cup has been removed you need to look down in the head where the cup seals and clean it. The factory uses loctite as part of the seal and it drys in place and will sometimes stays stuck in the head. If you just put the cups back in they will not seal properly, so you need to pay careful attention about cleaning the surface in the head. Then get the outside of the cup cleaned up and get ready to reinstall it. With all your parts cleaned and ready to install take red High temp. loctite and run a small bead around the tapered area where it mates to the head and apply a small amount of grease to the o-ring. Slide the cup down into the head then lightly tap it down in place. Put the injector back in place and torque the hold down in place right away! This is very important as the pressure from the injector hold down is what keeps the cup in place. Reassemble everything else but leave the coolant out of the engine. I like to let everything sit for 24 hours so the loctite can fully cure first.

Then finish up and see what happens. The worst it can do is still leak and you lost sometime working on the truck.
 
I concur with what others have said, this should not be an issue with the work that was done by Merchant....sumthin ain't to Kool in the Koolaid

If you need someone good to work on it let me know, the Dmax tech that did warranty work on mine has his own shop in Ocean Springs now, I'll give ya his #
