Draw Straw Install and Killer Dowel Pin 24v

[rlane547]

I had two different questions and just lumped them in to one thread. First, does anyone have a good write up for draw straw install? Going to do it Friday and wanted to make sure I have everything I need. Second, I just read somewhere that the 24v's also have the killer dowel pin problem. In my ignorance I thought it was only the 12v. If so how prevalent is it? I worked for a company with a fleet of over 100 6bt and 4bt engines and never saw the killer dowel pin however I did see the bolts back out of the housing on two occasions. I guess I'm wondering if this should be a 911 issue?

It's possible to have the KDP, you won't till you take the timing cover off...my 01 didn't have it. 98-00 were more prevelant to have it than 01-02.

Neither of my 99's had it. They fixed the problem by stepping the hole. That's no guarantee that yours does not though.

i looked for the kdp on mine during rebuild and the hole for the pin had a step down cast into the gear housing to where the pin cannot come out.

but as stated, you wont know till you look at the housing

Sometimes I wish you guys would lie to me and say everything is fine don't worry. Just kidding. Looks like I'm taking it off. Too big of a gamble not to check.

From what I understand, the most prevalent ones are the 1998, 1999, and 2000 trucks. They seem to be hit and miss even in those years. The only way to know for sure is to pull the timing cover. I tabbed mine in 2 1/2 hours in my driveway with hand tools so if you have shop with air tools you should be in the 2 hour range I would expect. Just remember, the fan has left hand threads.

My 98.5 had it. All you need is a 5/16 fender washer, and grind it down to fit in the corner of the casting. Be sure to use Loctite on the bolt and torque the case bolts to 18ft lbs.

if you look you can see they cast a step over the hole for the dowel

My 98 had it too, I tabbed it when I p-pumped her. It was about halfway out iirc

What does the OEM non killer look like?

You can't tell by looking at the timing cover. The only way to know is to pull the cover and look.

I have my tank down and the module removed ready for the draw straw. I noticed there is a port on the draw straw for return fuel from the fass. Right now I'm running it back to the filler neck. Is there any benefit running it to the module?

[Mopar1973Man]

Yes. You want it return to the module. This returns more fuel right and the suction tip preventing the 1/4 problem. Ask Eric at Vulcan Performance if he has a way to resolve the old filler neck or cap for JIC.

Thanks Mike. So I can eliminate the filler neck tee now and both of my fuel returns will go directly into the draw straw/basket

[rlane547]

Draw straw install finished and 1/4 tank fuel issue resolved. That was the worst fuel strainer basket I've ever seen. Couldn't even see through it.

[CUMMINSDIESELPWR]

one thing down, did you get to see inside the gear case for the KDP?

Should I be worried on my 98 I have 315k what happen when it falls out. I thought that was a 12v issue. Hmm one more to add to the list

Some of the early 24 valve engines had the KDP problem. The only way to know is to open it up, although at that mileage, if it was going to fall out it probably would have by now. For a couple of hours labor you can find out for sure.
