what is this kdp, or killer dowel pin that ppl talk about and whats the big deal about it? iv seen it on here lots, tried searching but still know really have an idea of what it is. just trying to expand my knowledge database.....

The KDP is a locating dowel in the front of the block that tends to work loose over time. If it is allowed to fall out, it will be forced between the gears and the case, usually breaking a large chunk out and creating a huge oil leak.

Try this, on your web home page you should have a spot to click on for images, just type in killer dowel pin, alot of pictures of it

if it does happen to you and a new case is warranted you will not have to tab it. the new case holds the pin captive. it cannot come out

Here is a perfect example, but many have had far worse hits.............

i see.......thanks for the info. at what point mileage wis does this pin fall out usualy? im at 270000kms and i doubt its been looked at......

There is no rule for it, its an engine part and can fail at any time. The repair is cheap and easy in comparison to pulling the front gear cover to repair the damage. I did mine at 150,000 km an it was hanging 1/4" out. It may have stayed there or not, but it wasn't where it was supposed to be. I have 350,000 on it now and its worth not worrying about.

Or it might have already fallen out and not hit anything........

infidel

I've seen KDP cracked case damage ranging from 48-325k miles.
Mileage makes no difference, it can happen any time.

If you take the cover off to look at it definately do the fix. I would do it sooner than later cause its not hard to do. My only mistake was jacking around with trying to get my fan off for a while until infidel or somebody told me to just remove the fan pulley bolts so you can remove the fan and its mount all in one. After that its a piece of cake if you remember how the ess wire is routed and where the longer bolts go. I installed the new seal on my work bench. I couldnt imagine trying to install the seal after.
