    86 f250 6.9 rebuild/refresh advice and questions

    Made smoke yet? The blue looks better than I expected but I still like grey better ( : < ).

    Somebody shoot me!

    That's the one I used for my 1st Gen Banks, too. You're in a hurry but don't corncob it! It will be a bear to redo later and it will be a source for water, dirt and generic grunge to get into your engine!

    Coolant in Oil

    No, the test plate plan is in the FACTORY service manual. I'm not sure it's worthy he effort to make it, frankly, because most people successfully reseal their coolers with no leaks. If you later decide you want it, I'll scan that page from the factory manual and post it. Most likely, it would...

    banks kit up and running

    My Banks kit (1st Gen)has the pyro mounted in the cast turbo mount, pre-turbo, just where the two pipes come in from the engine. Good spot IMO because it reads the blended temps from both banks. Somewhat a pain to get to (don't know what setup you have) but only about an hour when I had to...

    Somebody shoot me!

    This should have been the second or third post in this thread instead of people making wild-assed guesses about what the torque should be and potentially steering somebody in the wrong direction! ARP has the instructions on their website to be looked up! Kudos to you bbjordan. I retorqued...

    **UPDATE** FP DIESEL GASKET SET

    FP is Federal Mogul. FelPro is Federal Mogul. Has someone directly compared a current production FP gasket and a current production FelPro gasket? Doesn't seem logical for Federal Mogul to make two sets of gaskets for the same application. Not impossible, though, and if they are different, they...

    Coolant in Oil

    May I respectfully point out that your first parts purchase should be a service manual. Preferably the factory service manual and/or the factory diesel supplement, a reprint of which is available online. I bought factory manuals when I bought my truck in '87 and even though I had training and...

    FS-2500 bypass filter system

    Well, the oil is worth a try. Lots of guys are doing it. Successfully! I'm on the last coupla months of a book deadline, so I'm not even thinking about trips out yet unless it's related to the book. The old truck is a horror right now anyway. It's either sitting or being rode hard and put...

    FS-2500 bypass filter system

    Even though this is better suited to the 6.0L section (but since you are admin ( : < ).... ... and forgive my upcoming "Tough Love" here ( : < ) All the HUEI engines are known to shear the oil, less so the Group IV PAO synthetics which use fewer VII (Viscosity Index Improvers, which are...

    FS-2500 bypass filter system

    What's your OCI, Mel? I'm wondering how far you've stretched it and what oil you use? I think we may have talked about it at one of the IDI meets but I no longer recall the details.

    Coolant in Oil

    The cooler is MOST likely. The only way to test the cooler is to pull it, mount it on a test plate and put in under pressure. The manual has the plans for how to make the test plate. I suggest you buy a manual! Anyway, if you are going to pull the cooler, just reseal it. The plat to test is...

    FS-2500 bypass filter system

    I think Blackstone does an acceptable job and they make it very user friendly to do oil analysis. The worst part in my opinion are the comments, which are too "folksy" (just the fact m'am for me). Polaris uses higher grade equipment, reputedly, but their service requires more ability from the...

    FS-2500 bypass filter system

    If you are going to run a high efficiency premium oil filter on a short interval, it's the same waste of money on a smaller scale. Keeping the oil cleaner results in longer lasting oil. There are too many variables to make a broad statement as to how much longer, you would determine that by oil...

    FS-2500 bypass filter system

    I DIDN'T, YOU DID. You posted an advertisement that was supposed to bolster your point about bypass filtration. It cited three SAE tests, 881827, 881825 and 95255 and included a few selected snippets from them. I happened to have the full SAE 881825 test here (which I bought for $22). I have a...

    Well, the old saw, "When it rains, it pours" comes to mind. You'll get thru it. Can't really tell much from the video, sorry!

    Coolant in Oil

    Just use a cooling system pressure tester. It screws on to the radiator filler neck. If you don't have one, Harbor Freight has them inexpensively priced. If you have a store nearby or online mail-order. Many auto parts stores also have them, sometimes to rent. If the water comes out of the oil...

    Coolant in Oil

    Really, could be any of the above but because of the indicators, the metal in the oil and the noise, the damage may already be done. Potentially, the more you drive it, the more damage you may be doing and the more it will cost to fix it when you do. Best advice is to fix it ASAP. The cooler...

    oil pan replacement

    I dropped the pan on my '86 back in the '90s and it wasn't horrible. But that's the perspective of a person who made a career of working on some of the hardest-to-work-on cars in the worlds (such as Porsche). My exact recollection is not 100 % clear since this was back in the '90s, but I did it...

    FS-2500 bypass filter system

    You are (likely deliberately) misinterpreting what I said. Or maybe you just don't understand as much as you think you do. Besides, we basically agree that bypass filtration is "good." My contention is that the ROI (return on investment) is NOT always good and you need to evaluate that before...

    86 f250 6.9 rebuild/refresh advice and questions

    Yeah, I was Army in the early '70s (an Army sailor believe it or not) and the post where I was stationed had a great auto shop where I did a lot of work. Any and all kinds of work, though they were a bit short of certain special tools.

    FS-2500 bypass filter system

    Bypass systems are a good thing but they don't pay for themselves in the short term. They are best considered a oil life extender versus an engine life extender. The difference in wear between using a bypass system and "normal" maintenance oil change intervals is pretty small and the benefits...

    Not sure MOA would be appropriate for break in... at least the MOA I used to be familiar with. In the '80s and '90s, it has a pretty strong dose of an anti-friction additive that might be counter productive to break in. I say that without having seen a recent Data Sheet on it.

    A Few Engine Overhall Questions

    Look thru the online parts catalogs. FelPro, Victor... satisfy yourself. Gather the specs. If I remember correctly, the major manufacturers all went to what is essentially turbo spec gaskets. They are all better than what was available in '88 or '93 due to advances in technology. Also research...

    86 f250 6.9 rebuild/refresh advice and questions

    FWIW, I used Rotella 10W30 T5 for break in with the additive. It's a syn blend and the "syn" is Group III. It's a pretty pretty robust oil. But no worriers on the Delo either... it's a mighty fine oil! And it has Moly, which the T5 does not. There is a Delo 10W30 too, but it's hard to find. Not...

    86 f250 6.9 rebuild/refresh advice and questions

    Some advocate (me included) using a lighter oil for break in, the reasoning behind that being flow. That would be 10W30 in our case. Flow's important for several reasons. You want good flow at first start and good flow thru the first warmup so as to flush out contaminants (there is a lot of dirt...
