Killed by the killer Dowel Pin

Its a dowel pin that is pressed into the block during assembly. It locates the timing case. Over time, they are known to work their way out and cause disaster. 1 of three things can happen. Option A: the dowel pin falls out, drops through the maze of crank, cam and accessory drive gears and lands harmlessly in the oil pan and you'll never know, and nothing will happen. Option B" the pin gets caught by the cam gear and is smashed into the housing busting out a big chunk. Cost of repair @ $1000 including labor. Option C: (The one that got me) the pin walks out, gets wedged between the cam and crank drive gear, breaks the cam gear off, busts a huge chunk out of the block, valves stop in their tracks, pistons hit the valves and the motor is trash.

OUCH! I feel your pain my friend. Just had to deal with this last week. The KDP fell out and luckily just broke a chunk out of the housing. I was able to find that chunk and JB weld it back together THANK GOD! I never did find the dowel pin though. Went through the oil pan with a magnet but never recovered it. Wondering if they guy i bought it from knew about it and sold it quick. Oh well its fixed now.
Good luck!

So option A, can I just take it out and throw it across the garage and put the cover back on? Or should it be staked or have the other cover put on? I just put a new radiator in and I don't want that little pos messing the engine up.

The fix is to pull the balancer and timing cover, set the pin back in if it's sticking out at all, and then bolt a little tab in there to hold the dang thing in. Odds are it's not sticking out at all, and then throwing it across the garage wouldn't be an option, but you'll still need to tab it to keep it from walking out later.

The one big downside of the kit is that it doesnt come with an actual timing cover gasket. Granted it comes with that grey sealant but Im not fond of using that stuff exclusively. Youd still have to go and deal with the dealer and get the gasket, if youd want to do it right.

I found a kit on http://www.pdrdiesel.com/products/KD...n-931-146.html but it doesn't come with a bolt for the tab. Is there already an existing bolt to use? Thanks

The problem with those kits, is that they're geared towards 2nd gen engines. In our engines there is a step from the timing bolt up to where the land for the pin is, so the tab has to have a bend in it. On the 2nd gens there is no step so the tab is just a flat piece of steel with 1 hole in it.

there is a TST kit for the early engine, with the bent tab.
I used the TST kit, and it was easy, and I didn't have to fool around making a tab. I also didn't have to drive 50 miles to the dealer to pick up a seal. But I wish it had come with a real gasket. I have a little bit of an oil leak now, even though I thought I was being generous with the grey stuff.

Some get a slightly longer bolt but others have used the existing bolt which is right next to the KDP.
Here is mine when I tabbed it a month or so back.
There is a bolt right next to it. I dont know why I didnt get a pic after I tabbed it. I think I was just in a rush to put it all back together and forgot...
