Its been a long time since I have posted on here since I sold my idi, nice to be back.
Ok so I currently have a 1997 7.3 powerstroke that is blowing out blue smoke pretty heavy at first start up then it settles down. It still smokes a little, but is clear that it is blue. When I give it throttle is starts pouring out blue smoke again. Now I thought maybe the turbo was in need of a rebuild, but I just went out and checked the end play on the shaft and I am not getting really any movement in or out or up and down. The shaft seems to be ok. So I took off the intake manifold after the turbo and there was some oil in the turbo but did not seem like enough to cause this much smoke. So I left the intake manifold off and started the engine and it still smoked like crazy on start up then cleared up. So i shut it off again and then it did the same thing. So I am pretty sure the turbo is not my problem.
Now the engine runs great, no missing, runs smooth and no loss of power, no oil in coolant or coolant in oil, no fuel in coolant and no oil in fuel. I am not sure what would be causing this at this time. I am thinking maybe injector o rings? or maybe head gaskets? I am not sure. Any help would be appreciated.
Just a little history on the truck, I bought it from a friend, he bought it from a landscaping company. Only has 155,000 miles on the truck. He drove the truck and on the way to his cousins house it died. He said the fuel tank and filter were nasty and gummed up and there was water in the tank also. He cleaned everything and could not get it so start. He is not a mechanically inclined person so he sold it because it was just sitting for about 4 to 5 months in his driveway and his wife was pissed about it. I bought it, and after replacing the IPR, IDM, and some rotted fuel lines the truck fired right up and runs like a champ. Just have this smoking issue now.
