Update

Thanks to everyone for the replies.

I visited Rockin S last week and have ordered re-man stock injectors, stainless rotors and new pads along with a set of u joints - just waiting for the parts to come in... probably ought to replace the fan clutch while we're at it. Gotta do something, it took 15 minutes to start after leaving it unplugged all day Tuesday in zero temp.

Answering some questions, stealer didn't print out the compression #'s so the first thing we'll do is get real numbers for all cylinders and go from there.

I live W of Denver in the foothills and commute to one side of the EJMT or the other 4 or 5 days a week. The only trailers behind me have had boats attached (2 to 8k #'s).

Plan is to spend next summer in New England racing my sailboat so the truck has to last until then at least - hoping the repairs do the trick. I'll post the compression numbers when I get 'em.

Sounds like GPs & GPR would be a good investment...

Are they stainless rotors or “e-coated” rotors?

Count me as one of the people who finds it hard to believe that truck is worn out. If you could drive it to Tucson we have a very good and reputable independent shop here, or maybe do the work yourself if possible. Following along to see how this comes out and betting that there are many more years left in that truck.

Out of the shop

The truck came out of the shop last Thursday - new LF hub assy, new injectors, new shoes for e-brake, new SSBC stainless steel vented (not drilled) rotors and pads, new spicer U-joints for the rear and a rear diff fluid change along with the Marinco mod (that puts the block heater plug in the bumper) and an empty checkbook.

Cylinder pressures aren't fatal but they aren't all that great either:

#1 - 241; #2 - 222; #3 - 234; #4 - 222; #5 - 220; #6 - 279; #7 - 237; #8 - 210

I still have a roar at 2250 rpm that's probably my fan clutch which has been locked up for a while and will get fixed next time there's money in the checking account. The roar is worst when cold and shakes the whole truck. The white paint is falling off too but it'll have to wait.

GP's and GPR were in good shape - what's a uvch 79jasper?

Thanks to all of you for your advice - truck turned 400,000 last Thursday!!!

UVCH is the under valve cover harness - it connects the plug on the valve cover gasket to the injectors and glow plugs. It is a known point of failure, but the 99-01 models were more prone to losing the connection at the plug than the later models.

It is piss poor and it's what I've got... once the ol beast gets warmed up, it runs like a champ (for now). I'd like to take the truck to 500k before either replacing it, rebuilding the engine or a long block.

Compression numbers are right on the hairy edge of toast.


Ford's criteria is that the lowest has to be within 25% of the highest. Your lowest number is 24.7% lower than your highest number.

I would get a timer and set it to turn on the block heater two hours before you want to start the truck. Also, I wouldn't wait too long to change the fan clutch. Mine let go and sent the fan into the radiator, destroying the radiator, fan, fan clutch, and water pump all at once. Expensive repair.

Stolen twice so far, but recovered both times with major damage.
