Phillip i never could get my 18's to burn clean at an idle, even with the 12mm pump. My 16's are really close to being clean in the summer time but if you step away from the truck and loookk reallly close you can still see it. Its the nature of the beast in my mind.

 

my ddp IV's get a little hot on the exh when towing up hills. i just turn on the snow. straight water when towing. cools right down then i turn it off on the other side. i'm a believer and it's easy. tc

 

how much timing can i run then with em,im lookin at jumpin a tooth(dont know which way yet,asumin clock wise) and stock at the mark on the case to start with,too much?

 

Mine was pushed to the head before I jumped a tooth. When I jumped a tooth, I put a timing tool in the pump so I would know where to start. That turned out to be the stock timing marks, they were almost perfectly aligned. I'm now about 1/16" past there, it sounded spooky at 1/8, and past there it would surge under light throttle at highway speed.

 

ok how do i get a timing tool and how do i use one? what do you mean that it turned out to be the stock timin marks,they were almost perfectly aligned,and now a 1/16 past there,it sounds spooky at 1/8.wanna?sorry i havnt figured out to do the quote thing yet

 

Sites that sell VW diesel parts usually have good prices on the timing tool kits. You use it by checking plunger lift @ TDC on #1.

When I jumped my timing gear a tooth, I put the truck on #1 TDC and installed the timing tool and wrote down the reading on the dial indicator. Then I jumped the gear a tooth and moved the injection pump until the dial indicator read the same as before (so the timing was the same). That just happened to make the stock timing marks line up. Then I bumped it about 1/4" and strapped it to the dyno. I wound up backing it off some later due to driveability issues and because it just sounded scary to me.

 

so then there is more to just jumpin a tooth to this i see.did you go clockwise when you did it. and im runnin stock timin on teeth but bumped up and my timin pin under the pump wont go into the slot on the teeth is that due to havin the pump moved

 

No, I just did it that way so I'd have a known point to go back to if I didn't like it.

Yes, the gear goes clockwise (as viewed from in front of the truck) one tooth.

No, either the pin is broke or stuck.

 

ok then it got stuck again or it could have broke cause it will move a very little,thanks wanna
