Scotty,

I got the pump back and installed. She smokes. Alot....

My buddy the diesel tech. says we need to mess with the timing. Ken said just line up the timing marks and go. Could it be becuase I don't have a wastegate so therefore I'm not pushing enough air until I start building boost?

Does it look LIKE THIS ? (http://www.socaps.com/photopost/data/21019/20DSC02933.JPG) http://www.socaps.comimages/graemlins/shocked.gif

Building boost shouldn't take too long. If you lug the engine it will smoke also. Timing should be 8* advanced for turbo'd IDI's. Aligning the static marks are for refernce only. To advance the IP turn the pump towards drivers side. If you have .030" between the marks that is about 2* in timimg. If you have the marks lined up try advancing it alittle. You'll be able to tell by the sound and how it runs.

Waiting and watching...........

That is alot of smoke. I checked on the timing and, my bad, advance is to passenger side, not drivers. What kind of intake do you have? You want as much air as possible.

Turbo, your truck NEEDS to be timed to 8.5*BTDC, if you have not had it timed the right way, check out Diesel Tune in Downey Ca. They will charge you about 70 bucks, but unless you do that, you are going to be guessing the whole time (no pun intended) if you are timed correctly. When I had my IP timed, I had it set to 6.5BTDC BUT that was to help out with the propane. You could also be seeing smoke since you do have a Non WG-ed turbo. My truck will smoke a touch, then once boost comes up the turbo clears it up ASAP. Godzilla was correct that you may need to add some newer style of intake. It is really easy, just a piece of pipe and the largest filter you can fit on the truck. Other than that, how is power once you are out on the road. I would think if you are making that kind of smoke, you should have a buttload of power at cruising RPMS once you have built up some boost. If you want, give me a call at 949-374-3490. Scotty

Did you change injectors also??

If so were they stock or did Ken open them up a bit?

Ok, we are now about 8* .12". Smoke is gone. A little now and again at the expected times. New "Ken" injectors to match pump. So far sooooooo Gooooooooooood!!!! I definitely will have it timed to 8.5* So no waste gate and can build boost in 2nd. Acceloration is unbelievable http://www.socaps.comimages/graemlins/shocked.gif... I'll be working on air this week.

I might be able to make out there. I have family obligations for the weekend, but maybe, just maybe they'll leave town in time for me to head out.

Ok, because I'm all mixed up on which way is which. I'm close to 8* towards the driver side. Looking from the front of the truck towards the back, the pump mark is to the right of the engine mark. The other direction, towards the passanger side, is when it was smoking like a James Bond smoke screen.

MPG is now at 17. Lost about 1.5 MPG. Could be the timing.

Towards driver is retarded and towards passenger is advanced. If it sounds realitively quiet, that would me retarded, if it loud and cackly it would be advanced. Sounds like you have it pretty close. Overall, do you think it was worth your time and effort? Sounds like the truck is running great and you are putting good power down. Scotty

I moved the timing back to center. Not smoking as much as last time. I'm going to leave it there until I have time to get it timed. Isn't there a truck place off of miramar road? Downey is a long drive.

Miramar Truck Center is probably the best place. Should be good enough to time your truck. They were going to charge me 70 bucks also, not too bad, but really not that cheap for a 20 minute EASY job. Scotty

any secrets on getting ahold of Ken? I want to know exactly where he thinks it should be. I emailed him last tuesday to let him know the fuel return fitting was missing from the pump. I still haven't heard from him.

The stamped marks are reference only. They are different from truck to truck. By alining them up you only get close enough to run. 2* timing is only .030" difference between timing marks, that less than 1/32". There is also a difference in what type of timing method you use, Induction (clamp-on) or Luminosity (light probe in cyclinder)method. 8.5* BTDC @2000 RPM( Pulse Method) or 1.5*ATDC @1400RPM (Luminosity method). Scotty's right, passenger side advance- drivers side retard.

Is the tool(s) too expensive to get? A trip to san diego seems like a hassle for something that can be done with hand tools.

Where did you have yours timed?

you're not talking to me are you? my failure prone CPS and ecm take care of all my timing needs.

...just lurking in this forum anyways...

A clamp-on adapter is the key. Most will work with a good timing light. The adapter translates fuel pulses (#1 injector line) into an electrical signal the timing light can understand. Then you time the engine by the marks on the vibration dampner. You would advance or retard the IP according to the timing. The adapter is not cheap, compared the number of times it will be used. I had mine done by a shop in Placentia, OC for $40.

I'll have to call around. By moving the pump back to center, I improved my MPG by 1mpg back to 18+ mpg.

I had it timed at Diesel Tune in Downey, but Miramar Truck Center can do it also. It is amazing that a little turn on the IP can do for power and mileage. I think that is why it is so important to get the IP timed to factory specs using the pulse method of 8.5BTDC, should have the most power and mileage at that setting. Retarded a few degrees will give you a little top end power, but right on the money is the best if you are not running any propane or meth. Scotty
