    parallel turbos

    It's the hex you see cut off at the bottom of the photo. What he's pointing at is the rotor inside of the head. Specifically the intersection of the inlet and discharge passage inside the rotor.

    parallel turbos

    I'd say your pump is bad. Timing should be set with the engine at operating temp, at 2000 rpm. Static timed, the pump/engine should rev up to 2000 rpm cleanly with no issues. The fact that you can't get there and various colors of smoking occurs when you try tells me there are internal pump...

    Valve Stem Seals

    IMO if you're turbocharged, at no time will there ever be a vacuum(pressure below atmosphere) in the engine. Even if you weren't the tiny amount, if any, of vacuum created would be very difficult to measure. Like inches of water small. Not enough to pull oil past a correctly sized guide.

    Valve Stem Seals

    That's what I've contemplated doing. So long as the guide-valve clearance is correct, it will be minimal. These engines seem to chew through guides as is, not sure if you could over lube them. This whole topic has me wondering why the idi's do go through guides as bad as they do. Are the rockers...

    Could you Sleeve down an old crusty 7.3 to run 6.9 pistons???

    silvolite is made by uem. TRW(sealed power/speed pro) hasn't shown stock for awhile now. Anything you find is NOS. If you've got a source for them, buy them up and set yourself up as a little niche reseller.

    Could you Sleeve down an old crusty 7.3 to run 6.9 pistons???

    Found it on facebook. According to justin anderson (r&d), 6.9 pistons have been obsoleted by mahle, and uem. Custom pistons are made frequently, but they're typically made off an existing forging/casting. As far as billet pistons are concerned, I don't think those are exactly affordable...

    Traveller Smurf (Cubey's '89 van)

    I'm sure there are some that are from the usa and ship from warehouses here, I've just ran into it before where the seller said it was in the USA and what I received was shipped from overseas. As a buyer, I flagged it as not received due to the item being over a week late past the delivery...

    Could you Sleeve down an old crusty 7.3 to run 6.9 pistons???

    I'd be more concerned with finding pistons. Somewhere I read that 6.9 pistons are no longer made and will be obsolete, any truth?

    Traveller Smurf (Cubey's '89 van)

    Yeah I've seen that before. Actually as recent as about 2 months back for the wife's xmas gift. Site I bought from showed a NJ address and Fedex showed "shipping label created, awaiting package" in NJ forever. Dug a little and found it was coming from where it was made in Israel, and into NJ...

    Traveller Smurf (Cubey's '89 van)

    Bypass the mechanical, or remount the electric after the mechanical. I don't like feeding mechanical pumps with electric pumps as the chance is there to rupture the diaphragm in the mechanical unit, and then pump the crankcase full of diesel. The 4070 will be okay feeding an IDI by itself if...

    Traveller Smurf (Cubey's '89 van)

    Jumping threads here, but that electric pump is a p4070 right? Those are vane style pumps and are not draw through, so your test wasn't accurate.

    Timing related to cold starts

    Timing matters some. If you have a slow cranking pig that's low on compression it won't matter. But if it's out a mile you'll get a better experience having it where it should be. You'll actually want it near 0(retarded from normal) for better cold starts. Has to do with more heat in the...

    parallel turbos

    I know it wasn't addressed to me, but I'll give my opinion. I "learned" mig first, in the shop as a teenager. Had no idea on anything, except that pulling the trigger made stuff stick together. I then went to college and actually learned mig, then stick, and then tig. I'd rather have learned...

    parallel turbos

    If it's a 3 in 1 machine like that then I'm sure it is. Mig works well on mine. The newer machine I used in college was better, but what I have gets the job done. Tig on mine is just okay. But then again, I'm basing it off a new lincoln precision tig that I learned/played with in college. The...

    New to us truck at work.

    That's normal. Dad has an 04 f350 4x4 v10 automatic and gets about the same 8 loaded/10 unloaded. About the only thing that I know of to increase fuel mileage is to place a rock behind the gas pedal. No k+n filters, air intakes, headers, or other gimmicks work. Normally you can eek half a mpg...

    parallel turbos

    Those are all exhaust pieces, none would be galvanized, or I'd have been dead years ago. Most is aluminized, which is why it can be welded. I use .030 er70 wire with it. I really want to try .023 the next spool, as I've been told by exhaust guys it make a big difference in blow through. I...

    Carter P4070 Electric fuel pump failures.

    Yeah hewitt's site sucks. Their sales team on the phone is top notch though. Any questions give them a call. They make aircraft gauges too fwiw, I'm not 100% sure on this, but I though anything that was used on a plane had to be certified by the faa. I don't think they'd certify junk. I'd rank...

    Carter P4070 Electric fuel pump failures.

    Hewitt offers a 0-15 psi fuel gauge. https://hewittindustries.com/product/100-10x/ and to use a mechanical gauge in the cab, all you need is an isolator, which is something they offer as well.

    parallel turbos

    Did you get a good deal on muffler extensions? Typically an 8' stick of pipe is less then half of one extension and any muffler shop can swage the end for you.

    Dana 70hd fluid recommendations

    Synthetic or conventional any gl5 75w90 or 80w90 will work. If you're towing a lot or heavy like an rv, you can use a 75w140 instead. Use a bottle of friction modifier if you have an lsd, even if it says it's added already in the fluid you choose. They're not too picky in my experience, just...

    Zd29s vs Zd9s...for the inquiring mind...

    80024 interchange to 12g. IIRC the 12g was self limiting but in 6.9 plug size, no modification required. On paper they would have been great, but when I bench tested a set of 8, all failed after a few lights with 2 blowing off the tips. I read at the time that it was because they sat on the...

    Zd29s vs Zd9s...for the inquiring mind...

    I doubt a grid heater would work. I don't think it would get the pre chamber hot enough. If you've never experimented, even with it being 70-80°F and the engine cold you still need some sort of heating aid, whereas a DI engine is good down to below 40 usually. Just the nature of an IDI engine...

    Anti Gel Product (Howes)

    #1 diesel is similar to kerosene. Kerosene is a little better refined with less impurities so it can be burned indoors. #1 also typically has the addition of road tax, whereas k1 doesn't. Regardless, both have a similar cloud/pour point of around -40. Winter fuel is what would be cut with...

    Anti Gel Product (Howes)

    I've seen issues with howes not working to prevent gelling, Never used it myself, so it might have been bio-related too, I don't really know. I used to swear by power service white bottle. It's all we've ever used. We maintain a few fleets. We had near 0 weather predicted this past weekend, so...

    Trying to identify manifold coolant sensor

    Definitely the 6.9 glow plug controller, it's what would have been stock on your 84. Having a later 7.3 installed, they likely swapped it to the 7.3 because they didn't know it wasn't needed.
