    Looking for a late-production 6.9 engine

    With Christmas vacation ahead of me, I'm back on the hunt. I'm looking for a good rebuildable 6.9, preferably a later production block casting, but I wouldn't turn my nose up at a good 6.9 of any ilk. I live in Austin, so somewhere in central Texas, but for the right deal I'd drive to LA, AR...

    Here's a new one...rat(s) in the CAB

    Yeah, so I got an unpleasant surprise yesterday when I got in my truck...RAT droppings...A LOT of them. Double-U-TEE-EFF?!?! Looks like the damn thing gnawed through the fan cowling (the interior one, for the recirc.) But, how in the hell did it get that far? Found droppings on top of the...

    6.9 -- late S/N vs. early S/N block question

    Hi folks-- So, I'm on the hunt for a good rebuildable 6.9 engine, and have been looking exclusively for a late S/N block which I've read is a stronger, beefier block. However, I'm finding that 6.9 engines aren't exactly falling out of the trees. As I understand it, the later blocks have a...

    Looking for a good rebuildable (or rebuilt?) late S/N 6.9

    I posted this in the want ads section, but figured I'd paste it right smack in the middle of IDI Nerdville as well...:D Hi folks. Looking for a good late S/N 6.9 IDI; 6.9DU2U174*** or higher. I live in central Texas, so it'd have to be somewhere in Texas or a surrounding state for me to pick...

    Need a good rebuilt or rebuildable late model 6.9 IDI

    Hi folks. Looking for a good late S/N 6.9 IDI; 6.9DU2U174*** or higher. I live in central Texas, so it'd have to be somewhere in Texas or a surrounding state for me to pick up, unless you're heading my way. I'm interested in either a good builder or possibly a well-built turn-key engine, but...

    6.9 "Wellness Check"

    Howdy. Wondering if there's a way to check the overall health of my old '86 6.9 IDI. Necessity dictates that I sell one of my vehicles, and I'd rather keep my truck. However, I'll have to depend on it getting me around as my main mode of transport. Of course there will be the general fixes...

    Finding a good rebuildable 6.9

    I'm starting to think about finding another engine for the ol' gal and building it up a little at a time. Any advice on what (and where) to look for in a good used 6.9, and what I can expect to pay? I'd imagine they're a little hard to find... I live in central Texas, BTW. Thanks!

    Doing a rear brake job? READ THIS!

    As we all know, not all brake shoes are created equal. As it turns out, even equal brake shoes are not created equal. I did a brake job 6 mos ago or so on Maxine. I always buy the best parts I can get, but more and more, the only thing you can get at the parts house is junk. I've always...

    Emergency Brake Emergency

    Hi fellas-- I cannot get my emergency brake to work. The story goes like this: The emergency brake worked fine when I got the truck last year. It worked fine in spite of both rear drums being full of gear oil and the rear shoes literally crumbling away in black goo. I replaced the rear...

    A couple of probably dumb questions...

    The 'ol gal has been right as rain since the fuel supply debacle of last summer (knocking on wood...) and so I have been doing more driving and less wrenching, which is a good thing. I am, however, the type of fellow who wonders when the next shoe is going to drop. So, a couple of things I...

    6.9 rebuild

    Thinking about rebuilding a 6.9 for Maxine. I'd rather find another 6.9 to build and then swap out engines. I have a few initial questions-- --What's a reasonable price for a rebuildable 6.9? --Any particular issues I should look for in a builder? --How heavy are these engines? I'm...

    Fuel additives?

    There are a plethora of diesel fuel additives on the market. I had no idea diesel fuel required so much "baby-ing"--or does it? I'm currently putting in 8 ounces of DieselKleen with every tankful. That seems to be the most common additive that folks use. But what/when is there a need for...

    Facet/Duralift filter -- waterblock???

    Wondering if the bowl filter on the Duralift pumps are water-blockers...?

    Fluid Dynamics (or how does this diesel thing work?)

    In my ongoing quest to figure out my air intrusion problem, I just want to make sure I have it in my head straight about what is going on in my fuel system that's causing me the problems. The air is causing the fuel system to lose it's prime by allowing the fuel to drain back to the tank, is...

    Air in fuel lines

    So I replaced the sending unit in my rear tank last week, and ever since then I'm getting rough idle on start-up. It only runs rough for a few seconds, and then it smooths out and runs fine until the next start-up. I've opened the schrader valve on the fuel filter a couple of times to try to...

    Low fuel level in filter bowl -- BAD??

    Hi folks. Welp, just finished putting a new sending unit in the rear tank, so I can now get every good-to-the-last-drop bit of diesel in the tank, AND my fuel gauge works again. WOO-HOO! That's high livin'! Anyhoo, Maxine ran out of fuel (again) the other night, which prompted me to get...

    Drop the tank or lift the bed?

    Hi folks-- Putting a sending unit in my rear tank this weekend (I hope). I've noticed in my previous threads that some guys have mentioned lifting the bed to do that job. How is such a thing done? I am assuming it requires a hoist or an A-frame, of which, I have neither. It sounds easier...

    Cheap-O clutch master and slave cylinder?

    I've spent a little time under my truck lately, and I noticed that it has what appears to be a fairly new clutch slave cylinder and master cylinder as well. However, they're PLASTIC, as is the line. :wtf: The clutch doesn't feel all that great, although at this point it is functional...

    Cavitation question (yes, I read the sticky)

    So after reading the article (which was very informative), I'm still wondering about whether to change my coolant and put in the additive. My take-away from it was that if you run a 7.3, you'd better damn well be running additive, and if you're running a 6.9, well, it's probably a good idea but...

    How many miles to a tank??

    Just curious if any of you have set your trip ODO when you fill up and see how many miles you get on a tank---namely, the rear tank. Sending unit is dead, and I have a new one on order, and will probably put it in sooner rather than later, but might need to guesstimate on my fuel consumption...

    Is there any more black....?

    The answer is no, there is none more black. I changed the oil in Maxine, and boy was it black. After a filter change and refill, I checked the dipstick, and my new oil was instantly black. I know diesels are sooty, so I'm guessing that's more or less normal. Is it? When I had the valve...

    Stock nylon fuel lines or rubber fuel lines??

    I'm pulling my tanks out and replacing a sending unit in one and doing a showerhead mod in both. I'm also either going to go with a 38 gallon rear tank and do away with the dual tanks, or replace the fuel control valve and put both tanks back in. I haven't decided yet. While I have all...

    Newbie needs help with his first diesel (Please)

    Just started my first foray into the wonderful world of diesel motoring. Many thanks to Rudolf Diesel's mother for having such a bright and inquisitive son to develop an internal combustion engine which requires no repetitive electrical ignition. But, I digress-- Just got an '86 F-250 w/ a...
