WHIFF

I parked my truck yesterday after doing a little bit of hot rodding (and letting the turbo cool) and when I came back to the truck about 1/2 hr later, I noticed about a pint of oil dripping off the front axle. It kind of looks like it's coming from the timing case, but it can't be the KDP. That thingy's dead. Any other ideas?
Help!

After further examination, I determined the oil is dripping slowly out the front of the timing case. We're talking a drop or two a minute, when the truck is running. I'm starting to worry about this!

Even if it is out of the front of the timing case, it don't mean the KDP strikes again. It could be something as simple as a bolt falling out or maybe even the crank seal leaking. You should try to clean things off good to try to locate the leak. Did you check to see if the bolts were tight? Look at the simple things first.

You say the KDP's dead, did you do the jig fix (update your signature, you're confusing me)? If so, what did you use to seal the setscrew? I noticed mine was leaking last week (not near as bad as yours) so I pulled it apart and gobbed blue goo all over it. Seems to have cured it for me.

WHIFF

Sorry to confuse in the sig, I jigged it. Only used loctite to seal the set screw. I wouldn't think it could be KDP since that's done, and the leak is so slow.
My guess is either bolts are loose, or the seal has been compromised. It's at a repair shop now. I'll keep all posted. And when they open the timing case, I'm gonna have them tab it so then I'll have it double-fixed.

OK, everyone, I figured this one out.
Apparently, I didn't jig correctly, since my KDP actually wiggled its way past the set screw I put in the timing case (either that, or the loctite didn't hold it in place.) I went by the shop today, where my truck now sits, and got some great pics of what KDP damage can do, even when I thought it was jigged. Bottom line--I took my chances with the jig and apparently, I must have screwed up the jig operation. Now I have a $1500 bill staring at me!
The good news is the new Cummins timing case DOESN'T HAVE AN ALIGNMENT HOLE ANYMORE! (Do you think Cummins might somehow be acknowledging the design flaw?!)

Anyone want to buy a jig?
I need to recoup some coin, or just go out and buy some alcohol to make me forget

I don't understand what you're saying.
Did the set screw come out or was it in the wrong place?

WHIFF

It came out, by the time I saw it. I didn't take the case apart.

I've loaned my jig out to well over 200 people and have never heard of a set screw backing out. I always figured the fan hub mount would keep it in since it's right up against the screw. In fact the mount won't fit unless the screw hole is countersunk.

an other reason to fix it the right way??
