    86 F250 6.9 IDI Smoking!!

    Cleaned and rebuilt the block from Mel and got the truck back up and running. Found a turbo 7.3 idi with full turbo kit (turbo needed rebuilt) for cheap so i picked that up and sent the turbo out to GPOP shop for rebuild/upgrade. Truck is back together, inspected and on the road. Currently...

    86 F250 6.9 IDI Smoking!!

    Problem is i cant find a reasonably priced machine shop local to me....I spoke with the 3 nearby (Philadelphia area) 2 didnt want to touch it and 1 said it would most likely be over $1000 just to bore .010" over. I called CDI and Mel has a block thats in good shape he is willing to part with...

    86 F250 6.9 IDI Smoking!!

    UPDATE: Finally pulled the motor and tore it down....was hoping to just replace head gaskets and throw some studs in. Found a crack in the #4 cylinder wall....the head gasket actually looked pretty good. So now i am in a debacle where I have quite a few new parts for a 6.9 idi, but cant find a...

    I aligned the marks on the pump/ housing. My plan was to take it to CDI to have Mel fine tune it.

    86 F250 6.9 IDI Smoking!!

    I did a compression check, drivers side front to back (320,340,340,300 psi) Passenger side back to front (400,360,400,350psi) The dipstick is black with oil, when I removed the old CDR it was filled with grayish really thick oil. It doesn't seem to be consuming oil or coolant.

    86 F250 6.9 IDI Smoking!!

    Ran it up to temp today with a 12v diesel pump from a 5 gal can into the filter housing and the mechanical pump going into a separate 5 gal can (was trying to bypass the fuel system to rule that out) After it came up to temp I was getting 80-150 dg F on my injector bodies. These are rebuild...

    86 F250 6.9 IDI Smoking!!

    I ran it for 10-15 mins and it smoked the street out. I will run it again this afternoon. I live on the edge of a corporate center, everyone going to lunch got a free smoke show haha.

    86 F250 6.9 IDI Smoking!!

    So I got the new injectors installed, bled the system and she smokes more than before.....ugh. Any input as to what to check next? The smoke smells like diesel, after the injectors it seems more white than blue as before. There was some condensation that came out of the tailpipe at startup, it...

    I will take a look at them, have to do some research as I have never inspected one before. I plan to change the diff fluid while I am back there.

    86 F250 6.9 IDI Smoking!!

    I agree, the good news is the truck was only $800 and its pretty solid. It wont be a daily driver, and I like working on vehicles so i dont mind doing the work myself and enjoy learning new things. Once the engine is all tuned up, new cdr, air filter, fuel filter, diesel kleen, oil change...

    86 F250 6.9 IDI Smoking!!

    I pulled the trigger on a new set from CDI. Hopefully they have a set in stock and I can get the truck up and running next weekend. Pulled the bed off today to do some rust converter on the frame - some surface rust that I wanted to keep from getting worse. Need to do the parking brake cables as...

    86 F250 6.9 IDI Smoking!!

    I was going to go the JIC route but there were not hydraulic shops open on Saturday near me. I ran the truck today, got it up to temp and used a IR temp gun to measure the injector body temps.....anywhere from 85-140F. The truck fires right up and runs well, to me it sounds like the timing may...

    86 F250 6.9 IDI Smoking!!

    I was able to piece together a feed line from parts at Pep Boys. See below pic of necessary items. I used a 3/8" x 1/2-20 adapter and a 3/8" x 5/16" barb on the IP with O rings between each fitting, a length of 5/16" fuel line (bought 2 feet, probably used 18"), 1/4" MNPT x 5/16" barb on the...

    Appreciate the offer, Im gonna call CDI on Monday and see if they will ship me my old one. Unfortunately I start travelling for work again next week and will be on the road M-F for the next 4-5 weeks.

    86 F250 6.9 IDI Smoking!!

    So I picked up my Mini Moose IP from Conestoga Diesel Injection today.....however, I failed to remove the feed line adapter off my core.....so much for trying to get the truck running this weekend. Anyone have any luck piecing a new feed line together from local auto parts stores? I searched...

    86 F250 6.9 IDI Smoking!!

    Thanks everyone, i really appreciate the information and quick responses. I called Conestoga Diesel Injection today and was able to speak with Mel. I explained my situation and he was very helpful and patient to work with. He suggested a rebuilt IP and injectors. I told him I fine with the IP...

    86 F250 6.9 IDI Smoking!!

    I'm not in a position to drive it there yet, one because of the smoke (it gets pretty bad) and two waiting on the registration....silly Pennsylvania rules. I guess depending on the price it may be worth it. Id like to get the truck drive-able, if that means getting a donor 6.9 and rebuilding it...

    86 F250 6.9 IDI Smoking!!

    I will give them a call tomorrow to see what they have. Should I be worried about the steam coming out of the crankcase?? I'm new to these IDI and the ford CDR setup, I'm assuming it will have some but not sure at what point to be worried.

    86 F250 6.9 IDI Smoking!!

    I did not take temp measurements, I don't have an infrared temp gun but will look into buying one. It was pure clear diesel on the valley pan. I have extra copper washers from the return line kit. Is it worth it to replace the IP and see what happens? At the end of the day there is still oil in...

    Oh and it appears those plastic pieces I found are the lock tabs from the same kind of connector on the IP

    86 F250 6.9 IDI Smoking!!

    I removed the back connector and jumped a wire from the battery the rear terminal, it barely made a difference in the way it ran.....no difference in the smoke. The smoke seems to go back and forth from really bad to barely noticeable. I ran the truck at idle till it came up to temp and let it...

    86 F250 6.9 IDI Smoking!!

    I have only run it at idle in the driveway for a few mins. Today I replaced the injector return lines, o rings and cups, added a clear line to the top of the filter housing to see any air. Replaced glow plugs with motorcraft. Bled the lines and started the truck, did the injector test and it...

    86 F250 6.9 IDI Smoking!!

    Part of my plan once parts arrive was to do the injector test by cracking each line when its running. I am currently looking into replacing the metal return line back to the IP....The ferule or gasket fell apart and I would like to add a clear line to be able to check for air. Does anyone...

    86 F250 6.9 IDI Smoking!!

    Just bought an 86 F250 6.9 idi. It just had injectors (Stanadyne), glow plugs (no name) and return lines replaced and when the guy was test driving it, smoke started pouring out the exhaust. He told the owner it blew a head gasket and the owner did not want to put more money into it. Long story...
