    Let's talk filtration

    The problems here are; 1) Many people don't know much about fuel filtration or the right questions to ask. 2) Filter specs are not commonly or readily available. I have found that if you contact a company directly and ask for the filtration specs for a particular part number, they will give...

    The NIGHTMARE TRIP! Will I be asking too much of a IDI Turbo?

    I second this. What you gain with a rear disc upgrade on the old axle does not equate to what you lose. A strong parking brake is vital when you tow. Anyone who had had a park pawl jammed due to weight knows, plus a manual trans left in gear will not hold a heavy load on a hill. IMO, your...

    The NIGHTMARE TRIP! Will I be asking too much of a IDI Turbo?

    Certainly times have changed and if your 460 is an EFI unit, that definitely changes the experience. Still, even back then, remember it was 1985-ish, I knew about dynamic vs static and the cam duration was long enough, in theory, to avoid detonation. The FE heads weren't the best, certainly not...

    The NIGHTMARE TRIP! Will I be asking too much of a IDI Turbo?

    This discussion seems to be focusing more on making power than in being reliable when hard at work. Making power is great as long as you realize the cost and the consequences. The higher the power output, the more heat is created and the better the cooling system has to be. Bottom line is, "How...

    The NIGHTMARE TRIP! Will I be asking too much of a IDI Turbo?

    FWIW, my '86 spent a good part of its life towing at 18,500 GCWR. You can see the specs below. That's 1,000 lbs over the limit, in case you didn't know. The load consisted of an 8-foot overhead camper on the truck and a 30-foot trailer behind. There were times when I wished for more power, but...

    Anyone else still thinking of Spectre?

    Yikes! Hate to think of want went downstream!

    Anyone else still thinking of Spectre?

    What I don't like about the Tymar filter is that it draws hot air from the engine compartment. Think of how hot it gets. I've done IAT measurements on trucks with similar intakes and they added 100 plus degrees to the IAT versus a closed filter with ducted air. Remember that an extra hundred in...

    Fitting Valve Guide Boss in a 7.3 Head?

    I redid my pix so go back and look at the guide installation process. I have misplaced a shot of him drilling out the head, which he did on a big drill press.

    Fitting Valve Guide Boss in a 7.3 Head?

    I just looked at a set of head done about 12 years and 100K miles ago at a machine shop, where the guides were drilled out an new ones pressed in... most suitable for reuse! All he had to do is use an air hammer to drive out the old and then pressed in the new. Commonly done on many types of...

    Fitting Valve Guide Boss in a 7.3 Head?

    That's how it's done. Drill 'em out to a specific size and drive in a new insert. The parts catalogs list the guides. The Sealed Power number is VG-804 (intakes and exhausts) and the FP Diesel number is FP-1805407. I watched them being installed in my head. No worries! Easy-peasy job with the...

    Should I be concerned (water in oil)?

    What you cite is what we call anecdotal. In truth, a good detergent motor oil would do the same thing. There is chapter and verse on this if you want to look for it, but a lot of it is found in oil geek text. There are esters in SOME ATFs that do have some detergency and some ability to do a...

    Should I be concerned (water in oil)?

    Gotta call you on this. The ATF thing is a myth. ATF has LOTS FEWER detergents in it than motor oil (I could explain why in excruciating detail but just consider that the auto trans environment is a closed system without the input of combustion gasses... hi detergency is simply not needed). Plus...

    Should I be concerned (water in oil)?

    Frequent short hops in winter weather can cause this sort of condensation. Seen it many times and it is a well documented phenomenon. If that is how this truck is routinely used, consider the idea of a 195 degree thermostat, partly covering the radiator, or even (gasp) using the block heater...

    Any shop manuals better than another?

    Factory manual is the best. Anything else is just a cheap, abridged shadow of that. Go to eBay and start looking. There are also many specialists online that sell factory manuals. You can find decent deals. A cheapass Haynes is better than nothing but they try to cover multiple years. If you get...

    D'OH! Bonehead coolant leak, what to do

    OK, you got good advice here about the hole... but what about the original engine number? You'll have to get back to that eventually?

    Turboing a 6.9

    Correction: Banks advertised 250/550 flywheel (peak numbers) from the 1st Gen kit. I posted that '87 ad several times here. As with most ads, that is probably a bit optimistic... or optimized... but still a "best possible" number. We've seen some of the member's trucks on the board throw down...

    Head pull and replace

    Well, the timing and bad luck sucks, but you will be better off with a freshened set of heads. It's too much work to slap on a used set of heads and then have to pull them back off a short time later.

    Head pull and replace

    Cleaning the threads in the block with a bottoming tap is always an important step to getting proper torque on the bolts. AFAIK, ARP only has taps, not dies, but you can get a thread-cleaning bottoming cap (not a thread cutting tap, google it to understand the diff if you don't). You can use a...

    Head pull and replace

    If you want a quick-n-dirty test to see how well the valves are sealing, lay the heads up on the manifold surface and fill the ports with diesel fuel (at least unit all the valve portion is covered), being careful not to spill any on the outside of the head. Observe the valve for how much fuel...

    Oil Sample

    That's definitely the "glass half empty" outlook! ( : < 0) Plus, there are plenty of things a guy can do based on oil analysis. You can change the oil type, grade or maintenance interval. You can make a repair (when clearly indicated... and sometimes it is, unlike this case). You can change...

    A TRUSTED MEMBER THAT DON'T PAY.

    Threats of violence on internet forums have gotten people arrested. There was one very notorious incident on the Jeep G503 forum about 10 years that got out of hand and that's exactly what happened. Anybody seriously planning an attitude adjustment for someone is a fool to blather about it anyway.

    86 f250 6.9 rebuild/refresh advice and questions

    My '86 has the same aluminum side steps! I've hated them since the day I installed them in '87, but they are handy and my tiny wife needs them to climb in and out. It's been so long I don't remember who made them Dee-Zee, I think.

    All Blackstone tests come with sometimes colorful and entertaining commentary and recommendations. This is what makes them the most popular consumer-level oil analysis lab. They also have an informative newsletter and a website that you can learn a lot from. The high buck analysis??? You may...
