well everyone i got a problem. and i can not figure it out i am new to a diesel and i need the truck. now i bought the truck a while back spent a year redoing the body and frame, i installed new tanks and luk clutch, drove it had a knock, well i ran diesel kleen in her it went away. then i noticed i was only getting about 6 miles to 10 miles to a gallon. well i bought new injectors, i installed them and come to find out the ones in there had no copper washer well i installed the new ones with washers and a new return line kit. well i started the truck up and the damn smoke well i started it the next morning and she poured out the blue smoke. and now it has got harded to start and the knocking is back so i have no idea what is wrong and dont know where to start now.

Well if the only thing You changed was the injectors and return lines before it got this bad then I would check the timing on the IP and see if that improves things.

could it just need to run a while and clean up? air leak cause a knock like that?

Have you ran it at all since the injectors got pulled and the copper washers went in? You usually need to run it hard after the injectors or lines have all been off. From my experience, it'll knock something funny and blow white smoke until all the air's been blown out, which may take a few miles of hard throttle. If the only thing that's changed is the injectors coming out and back in with washers, I'd try this first, and as EZ said, get your timing checked.

okay how do you check the timing on the diesel and the ip pump. and i drove it hard for about 12 miles today. now she has more pick up but when i get on it there is no smoke.

 

[SKimballC]

No smoke sounds better than blue smoke, eh? Did your knocking clear up?

nope still there and louder then before but i am startign to narrow that to a exhaust leak because i do have leaking pipes under the truck and ai am about the fix all that with 3 inch but at idle she pours out the blue smoke

An exhaust leak will knock something horrible. AS long as it isn't a bad bearing or piston hitting the head or something of that nature it's not too bad. Also make sure nothing is laying on the injection lines as that too will make a knock...as will advanced timing. Regarding checking it...at home you can line up the static marks on teh pump flange and gear cover, if you have a lot of white/blue smoke and no power you can advance the timing a hair at a time... no more than a dime's width and always with the engine shut off. If it knocks you can retard the timing, again a little at a time, toward the driver's side to retard and pass. side to advance. For dynamic timing you need the right tools which mostly are located in injection shops and not even all of them have timing meters for IDIs anymore. Dynamic timing is 1.5*ATDC @1400rpm with the luminosity method or 8.58BTDC with the more common pulse method. Good luck and hang in there!

how do you advance the timing? that i dont know how to do i know the concept on the gasser but a diesel i am lost at.

 

[Exekiel69]

It is strongly advised to time it with a diesel timing meter specially if You don't know how to really get it on the sweet spot for the IP. One of the members here have a web page with very good instructions and tips on how to do it and with what You need to do it.

where can i get one of those timing tools at i can not find them listed at any of the parts store

 

[Diesel JD]

That was a pretty good writeup. I think I could time the truck by that if I had the tools.

There are no new ones. The best place to watch for them seems to be ebay. Those of us who have them, treat them like gold.
