    As far as I know you cannot buy from PAI directly. This web sight has all there stuff https://www.heavydutypros.com/cummins-engine-parts-engine-parts.aspx

    Volvo/mack I think uses cummins DPF components so you know one DPF system you know just about all of them. Detroits are a bit different but same basic concept. I have a basic understanding of cat's and cummins system but never worked on one. Do mack's use an 8th injector or do they use the engine injectors to inject fuel into the exhaust stroke?

    It seems internet forms just aren't as popular anymore. This forms my favorite so far and the community's the best and active. Smokstak used to be my favorite but all the forms are now either all politics or generator technical jargon. All the old iron people either died or stopped posting.

    Welcome to the form! We've got tons of info here about the old motors but we could use more stuff of the new emissions motors. What all do you work on with the emissions motors?

    Do you have a picture of that hump? I didn't know there was a difference in valve covers besides maybe an electrical terminal for the solenoid's. Maybe the 2 valve stamped steel covers had a hump but I can't say Ive seen a difference in the 4 valve cast aluminum covers. I know someone will know for sure.

    The patent office says there is a BROCKWAY GLASS CONTAINER INC and a BROCKWAY PLASTIC PRODUCTS, INC so the patent for the use of the name could have expired long ago but Im not well versed in the legal mumbo jumbo. I say bring back the Superliner to the U.S but there's no chance of that now that the long nose has gone extinct.

    A tip I learned but never tried is taking a torch to heat the cast iron before painting it. Tiny pores in the cast iron hold water and dirt, heating it supposably helps the paint stay on and last. The engine block has to be out and stripped down but if you're doing an out of frame restoration its worth it. Don't have to get it too hot and small parts can be baked in the oven if you're allowed to.

    My favorites were the ford GAZ engine and the Twin 6-71 Detroits.

    I love the Mack lettering! Dad had one with a straight 6 and a 4 speed, got good milage and could tow... slowly

    We have to pick just one? lol the c10 for me

    Heres stuff from a 1980 brochure: I think the tip turbine and the charge air cooler motors were produced at the same time then. Doesn't show a tip turbine 350 but I think you could get a rough idea.
  13. BOBWhite
    Intercoolers make just as big of difference as power is how I should have worded it ; ) We used to run a 85 350 E6 mack with an intercooler right next to our 70 1693 Cat without an intercooler and man what a difference. Granted the 1693 is a glow plug engine but still you couldn't be behind that thing for a good 1/2 mile without getting choked out by the smoke. That Mack engine ran so much cleaner and the same if not more power than the old Clatterpiller.
  14. BOBWhite
    Intercoolers make more of a difference than turbo's when it comes to power. That is if it has the tip turbine intercooler. I'm really exited to see that mack with an air starter! It'll be a showstopper for sure!
  15. BOBWhite
    Surprised to see it still has the twin turbo setup. Most I've seen chuck the twins for a big single. Twin turbo's heat up the air too much they say.

    There was a sticker on Macks (anyone have a picture of it?) that gives starting instructions that say to put the petal to the floor until the engines up to speed. John Deere engines start about how you describe by dumping a bunch of fuel into the cylinders and hoping for the best. Thats why the old ones start so violently. Macks start by retarding the injection timing and letting the piston compress the air to the max before injecting the fuel in. Macks always started really good compared to others it seemed.

    Yes most block heaters are in the same spot or take the place of freeze plugs. If your engine doesn't have a block heater than you'll have to take out a freeze plug and put one in. I believe there all about the same size throughout the industry so finding one shouldn't be hard. Ive seen some other styles that take place of radiator hoses and some in the oil pan but I think the block heater works the best.

    Did the head feel like it had been off before? Maybe someone before you tried to get it unstuck and that's the reason for the piston damage. The pistons can be reused if the ring groves are ok, a bit of pitting doesn't hurt too much I've reused some pretty bad pistons on stuff that just needs to run. I'm not sure if these have composite or aluminum pistons but if they're cast iron they are more like able to be reused. Porta-powers are a good method to remove a stuck piston if you have the right equipment.

    Does your shop have some sort of metal mites? You've got me stumped. Could have gotten some sort of acid on it or an electric ark shorted on it. Never thought I'd blame ball lightning for liner pitting.
  20. BOBWhite
    Wow that's cheap! No good reason to have a rough running engine with that price! Will an E6 kit work on an END675 series engine? Ive never seen a kit available for one of them. Also did they go to wet sleeve with the E7?
  21. BOBWhite
    Are these dry sleeve or wet sleeve motors? And if they do pop out why could't you just reseal it and pop them back in? You can check the condition of the cylinders and check for cavitation if they're out. Also do Mack's have problems with dropping or sinking liners like Cats do? I'd imagine sleeve shims would not be easy to find for one of these.
  22. BOBWhite
    What could be so hard about taking the heads off an old engine like this? Opposite the re-torquing pattern and then lift them off. I don't even think you would need a lift like a cat or cummins engine since it has two heads. And do you need to replace the head bolts and studs on something like this? I know now they have special torque to yield one time only bolts and studs but on old stuff I almost always reuse the head bolts.
  23. BOBWhite
    Isn't it awful finding online books for these? If you can't find the book then the standard torque values are your next best thing. This chart should help:

    Alright I need to know more about this corvette dash. Is it really the same one as used in a C2-C3 or is that just its name?
  25. BOBWhite
    If the motors stuck I'd take those heads off. They're going to be full of crud that'll need to be cleaned out, and leaving it will score up the cylinders. If the rings are stuck or broken it might not even start. Plus how do you know that it's the motor stuck and not the transmission or something else? But I'd be lying if I said I've never put a bar on it and broke an engine loose without removing the head
