Well , here is the whole story...
First of all , this isnt a 6.9 or 7.3. It is a 6.2 in my burban
. I snuck it in here becaus the pumps are very similar and the chevy section doesn't get much traffic.
I have been having issues with my only vehicle , my 1994 f250 idi , for awhile now. It is falling apart and I cannot repair it without pulling the engine and trans and going through them , but I can't because it is my only vehicle. Last year i was looking at a parts truck with a zf5 to swap in place of my failing e4od. I passed on the zf but I saw a 1991 3/4 4x4 4l80e 6.2 turbo suburban in the guys yard , which was exactly what i have been wanting for a long time. I talked to him about it , he was very attached to it and was reluctant to let it go , but i paid him what he needed to feel good about selling it. The story was that the previous owner put a new transmission in it , then the engine blew. He bought it and paid a mechanic to install his low mileage 6.2. After the install the mechanic couldn't get it to stay running so it was trailored home and parked ,and it sat there for years. I drug it home and started going over it. I found the fss and cold advance wires were switched , which made it run until the cold advance kicked off which shut the pump down. I switched them around and it ran without shutting off , problem solved ! NOPE. I tried to take it for a spin only to find the tratransmission was shot, turbo poured out oil , and a whole bunch of other nickle and dime things. I bought a new transmission, had the turbo gone through , fixed the other issues and fired it up for a test drive. Now that the transmission was working i realized it had no power , smoked a little and had a dead spot in the rpms. A fellow OB member helped me out with a used pump and injectors , so i installed them. At that point it ran better but would not idle down no matter what i did , i ended up deciding that something internally was damaged during shipping as the box was HAMMERED. This brings me to my current situation. I bought a new pump thinking it must be the problem. From the little running and driving attempts that it did over the year it smoked slightly more and more. Now it flat out pours smoke. NOW , hindsight is telling me many things , but as far as the engine goes .... it probably had a small coolant leak when i first got it which caused the dead spot right off idle, changing the pump seemed to help only because it idled past the previous dead spot due to something broken in the pump , and as time went on the leak got worse.
I don't believe the old man screwed me. I believe he got screwed by the previous owner , and by the mechanic which im sure didn't even swap engines like he was suppose to.
So now im searching for a cheap used 6.2/6.5 because i am into this vehicle way too deep.
All while my trusty old ford has been somehow holding in there !
