    WANT TO TRY A LIL BUDDY HEATER TO WARM ENGINE

    I have an old 6.9 F350 Dually crew cab with a 12' camper. I love the old truck and it runs great, I use it maybe five times a year for 3-14 day campouts. The only problem with the truck is that it hates cold starts, it'll start fine but likes to smoke until it gets warm. If I put it on the...

    Super smoky startup fixed!

    So I've been chasing this problem for several years, I've posted about it several times. Startup on my "86" f350 6.9 was smoky beyond bad, it was like a locomotive. I only use the truck for excursions into remote areas so I just kept putting up with it, it only did it once a day. It would...

    Thinking Of Plumbing My Two Tanks Together

    So I've been crawling all over my truck trying to fix any air intrusion leaks on my "86" 6.9 f350 dually 4 door. Today while laying under the truck looking at the Fuel Tank Selector Valve (FTSV) I had a thought. Why couldn't I stick a line into the bottom of the rear tank and run it level up to...

    Could Someone Explain How These Valve Stem Seals Are Supposed to work

    I just received new stem seals for my 6.9 idi. I'm confused, the intake (not shown) look like the originals but the exhaust are way different. Will these work? how do they work? The picture shows the old brown one and the new white nylon one. Is this just a short version of the old one? it...

    Will The Valves Really Drop Into The Cylinder While replacing the Seals?

    So I've been chasing a really bad smoke problem on startup, Injectors checked out so I moved on to replacing the valve stem seals. I read a lot about doing the job, It sounded harder than it actually was, I just made my own spring compressor and it worked great no issues getting to any of them...

    Would This Be A Good Engine For A Rebuild Project?

    I met a guy at the parts counter a few weeks back, when I was asking about parts for my "86" 6.9 IDI, he said he and a friend had just bought an "84" f250 with a 6.9. They were going to pull the 6.9 and put in a big gasser, he didn't think much of diesels. I gave him my number and he called...

    Need Torque Setting For Injector Body, 6.9 idi

    Working on my "86" 6.9 idi. I've got my injectors apart cleaning and re-shimming the pop pressure. I can't find the proper torque for the two piece injector body (the 15mm 12 point on the bottom), I find the 1 inch injector body to the head (35 ft. lbs.) but not the other. Thanks

    Question on disassembling injectors

    I sent my injectors out to get a 2nd opinion on the way they were popping, the injection shop agreed that they needed help, they thought they just needed a cleaning because they acted like they were just gummed up from setting a lot. They've had them almost two weeks and now say it will be the...

    ANTI SEIZE on INJECTOR LINES?

    When removing my lines to get at the injectors one of the nuts on the pump hung up on the line, just would not turn without taking the line with it. Eventually I just kept turning until it broke loose which twisted the line about 180 degrees. So I need a new line. I was thinking of putting some...

    POP TESTING, NOT MUCH POP

    Working on my 1987 f350 6.9 with really bad smoke on startup. Injectors were replaced 8 years ago but I've only put 19,000 miles on them,(sits a lot). So I bought an injector pop tester and I'm trying to test them myself. They all hold pressure up to 1800/1850lbs but unless I really pump hard...

    Could it be the glow plug selonoid?

    Been fighting this smoky startup (bad) for awhile on my "86" 6.9 f350. I'm on a manual switch, last week I pulled the glows out and I had 5 bad ones, they were only 1.5 years old with 5000 miles on them, they were Beru. I needed to get the truck going to deliver some wood. I could only find AC...

    Any concern with these compression numbers?

    I've owned this 86 f350 dually 6.9 since about 1990, not sure of the miles because the daughter of the original owner said her dad had disconnected the odometer. I'm guessing 250-275000. It's been running great but smoking bad on cold startups but starts easily. I replaced the injectors/injector...

    Ninth Glow Plug

    I remember reading some time ago where a guy wired a 9th GP on the dash inside the cab so he could see how hot they were getting. I've been using a manual button for several years and I like it, but I just pulled the GPs and had three bad ones. I am careful not to glow too long, 8 never over 10...

    Glow Plug Idea Question

    I've owned this 86 f350 6.9 for about 30 years. I always seem to be fighting with hard, smoky starts. I went to manual button 5 years ago and it's been better. I run the plugs for 8 seconds and then crank, I always feel like it needs more but I'm so afraid that I will burn them that I just let...

    Complete electrical failure

    I have a f350, 1986,crewcab,manual trans, 6.9. Just drove 450 miles to my hunting camp, parked for four days, went to leave and everything was dead, like a dead battery, but the batteries were good, messed with it for an hour and then suddenly power came back on. I fired it up and got about ten...
