    Free turbo with help

    It's an idi. They need higher compression than most DI diesels. No need to adjust the compression when putting a turbo on. The engineers who designed these things back in the day knew what they were doing.

    84 E-250 Barn Find

    Why buy an 06 F350 and put an outdated 20 year old motor in it? Me thinks emissions regulations might be a problem at some point either now or in the future if you do that.

    decked block/heads affect pushrod length?

    The lifters should compensate if you decked the block & heads within factory specs. If you took more material off than what was recommended, you might have some issues, especially fitting that intake manifold on engine.

    84 E-250 Barn Find

    WD-40 works wonders on tree sap. Might give that a try

    Wide radiator in Oregon?

    Oh? Didn't know that. :dunno

    Wide radiator in Oregon?

    How about a new champion rad. They aren't that expensive & work very well.

    Trying to replace thermostat, cant find replacement rubber seal

    The thermostat does not require a rubber seal around it. Never heard of that for these engines. I always put a little dab of rtv on edges to help it stay in place

    Tick, no tick, tick

    Can't hear anything out of the norm. These engines are notorious for making all kinds of noise, including ticking sounds. I wouldn't worry about any of it.

    IDI head removal question

    Wow that's steep. For these engines, it ain't worth it to dump that much coin in them. I'm sure you'll be able to find a good used engine you can rebuild. .030 is pushing it for a 7.3.

    E4OD guidance needed

    If I were in your shoes, I would really consider a ZF-5 swap. If your set on an auto transmission, go find a used C6 for around $200 and get it rebuilt & slap it in. It'll cost you at most $1500 to rebuild a C6. Yeah there's no OD, but those transmissions can hold 500 hp in stock form and are...

    TO THE PEOPLE RUNNING SPECTRUM STYLE AIR FILTERS......

    Another thing to add here is that K&N filter oil sucks. Every time I have used it, I have had a dusty oily intake system in multiple vehicles that I have had in the past. I'm also not a huge fan of K&N filters. Much rather have a dryflow AEM. I use a good quality dirt bike filter oil (spray...

    E4OD guidance needed

    Anything other than a jasper transmission would probably be better. They don't have the best reputation. My suggestion is to find someone locally that knows the E40D transmission very well and have them rebuild it.

    Finished Turbo Install

    Wow, nice truck! Looks better than some of the new rigs out there nowadays.

    Help me decide, E4OD vs ZF5

    No brainer when comparing the two. ZF-5 all the way. You will get hooked on headache medication if you go with the E40h sh*t :drunk:.

    Oil return safety announcment

    I've talked to multiple engine builders who say the exact same thing about these 6.9/7.3 idi cylinder heads. Sure the flow characteristics are great, but the casting or whatever material they used when making them wasn't the best. My 6.9 didn't have blocked off coolant passages FYI. From what I...

    Oil return safety announcment

    Yes & no. I found multiple cracks in the seats that extended into the cast along with cracks in between exhaust & intake valves. All of the precups were also cracked & some extended past the fire ring. Wasn't too concerned about that, since it's somewhat normal.

    Oil return safety announcment

    IMO the lower end of these engines are sturdy. Upper end not so much. Can't say I agree with this due to my experience with em. Yes these engines can go for many miles, but these cylinder head castings are junk. They are VERY prone to cracking. Can't tell you how many sets I went thru before I...

    Oil return safety announcment

    Wonder what the internals of that engine look like after a run away. Had to exceed well beyond 1200 degrees even if it was for a short amount of time

    Glow plug socket size? 3/8 or 10 mm?

    Wow thanks for the advise. Hopefully this helps someone in the near future cookoo.

    Vacuum pump leaking oil?

    Had a dorman in mine and seemed to work well. Never had any problems with it.

    2 Month Routine Squeak

    Spray some belt dressing on there and see if that helps.

    Wow that's cool. Love the duals w/o the fender flares.

    DO NOT USE WELLMAN GLOW PLUGS ON THIS ENGINE

    X2. Time to get a real mechanic that knows what he's doing other than draining your checking account. Something doesn't sound right with the story. Anyways, hope this gets resolved. Might be a good idea to get those heads rebuilt while they are off if you have the means to do so.

    Non Turbo IDI Ford 1987 6.9 Rebuild

    Did you say this engine has 875,000 miles on it? If so, that's ALOT. Don't think I've heard of an idi going that long
