It is free to join at www.dieselplace.com ......better try again...

As for your problem - glow plugs check out ok?....you might just need to get some new fuel in it - run some heavy shots of power service through it to clean up the fuel system....

if its white smoke its water in your system. replace your fuel filter, get new fuel, and ALOT OF FUEL SYSTEM CLEANER!! going by what you stated about it sitting most of the time there will be alot of water in the fuel tank. you will need to drain your water seperator (if equipped on the 6.2, i'm not certain). if it has one it should be by your fuel filter. water is attracted to diesel fuel for some odd reason (thats y the "water in fuel" light is in the dash.

ps... great buy, if you can get the motor runnin great then you spent less than what the motor alone is worth.

I tried that bot nouthing came out I put some power service in it to day it clered it up some but it stil smokes prety bad fiday iam going to try the outher tank that is empty to see if fresh fuel in it and one more bottle of power service in. I cant post pic's wet due to the fact that I live in N.J and I cnat reg it yet. I also checked for bubbles in rad and there was none and also for blow by took of oil cap while it was running and there was also no smoke and no oil in the air breather . is this a good sing?? I will keep you posted on what happens thanks

did u drain your water seperator and change your fuel filter? good that you dont have any blowby, means your rings are doin just fine.

today I put some fresh fule in the outher tank and after about 15 min it stops smoking I think it was the old fule then I tried the outher tank and then it started again i think they may have used off road diesel fule thanks for the help

FYI - off road fuel/farm fuel does not smoke any more than pump diesel....
