    strang sound

    My work truck started making some strange sounds. I can only say that it sounded like a very high pitched noise....almost like fingernails on chalkboard. It still ran great 36K and it's never been to the shop till now. I couldn't stand to have it puke on me in God knows where. The Ford...

    Lemon?????

    Ken @ DPS

    Anybody know the status of DPS? I realize some people have bad feelings for him, but either way it seems that he has had more sucess than most with performace IDI's. Seems possible that the bad press has pushed a wealth of knowledge away from the general public.

    TIMING

    When it's cool (30 F) my truck starts ok but not great. Not plugged in. I keep reading about proper timing on the IDI. From what I've read, the inj pump should be turned toward the pass side of the truck if looking at it from the front or radiator toward the back of the vehicle. My inj pump...

    IDI REBUILD

    :dunno Ok, I have never had this properly explained to me. 6.9 and 7.3IDI's do not have cyl liners from what I understand. So, how are these engine's actually rebuildable without replacing the shortblock. I've heard terms such as sleeving, and others I don't recall, but how is an engine...

    FUEL MILEAGE IMPROVEMENTS

    I run a 2007 (early) F-450 service truck with the 6.0L. I really like the truck and I've been through the 6.0 headaches with other work trucks. So far, this one is running great. 25000 miles so far and it has not seen the shop yet. Anyways, bossman is frustrated at the fuel mileage. This...

    MERCEDES ENGINES

    I don't hardly belong on this section of Oil Burners, but I'll fumble my way through this. My brother is getting into the trucking business and is looking at a Western Star rig with a Mercedes NBE 4000 engine running 370HP. I've had zero experience with this engine, just don't want my bro to...

    HYDROBOOST BRAKES

    I've noticed that a few members have done the hydroboost conversion. I'm interested as well and would like some feedback on how those who have done it are satisfied with it. My master cyl is going out, so may as well upgrade if I'm changing parts anyway!!

    Brand new to this site

    I've got an '84 F-250. Sort of inherited from my grandfather who purchased it brand new (it was his baby). I've had this machine for a few years, put new rims and tires on it, cut out the "soupbowl", straightpiped, new style glowplug controller, otherwise totally stock. 124,000 miles 2WD...
