  • Piston rings

    Just wondering if I can buy .020 or if I can find .010 rings for a .005 bore + (have the used .005 pistons already) ? I would ask Tom, but I might be doing that to much already Thanks, Pat
    Model A's and of course the famous AA's

    Pat, I'd wait until the cylinders are honed, and I take some measurements.

    I don't think we'll be cleaning parts with gas in that wood stove heated room. LOL

      I was hoping you'd say that Tom !! I heard if your close to the ignition point you generally come out unscathed Pat

    I am curious how anyone ever found .005 over pistons, that is a new one on me

    don't set the top ring too tight....we use .022 here, that ring is exposed to the max heat,
    that is another area I differ from the Les book.
    I have seen hot motors lock because of rings too tight.
    They expand as the motor warms up, so your starting gaps close up a lot

      Thanks for the input Tbird. I'm not sure when this engine was rebuilt or if the factory would use .005 pistons in some instances ?? Truck was purchased from a farm auction in 1961 and sat in a shop the whole time. There is plenty of gunk on the engine, so it would have been an early rebuild I would say. Pat

    Do any of the piston manufactures make pistons that take a modern narrow rings.
    by George Miller
    Narrow rings in IMHOP work better than wide rings. nWhat do you think.

    Reseat rings
    by DaWizard
    Something has been troubling me today.

    I can't remember if I heard or read something about reseating rings in a somewhat tired engine. The use of baking soda or borax or a gentle abrasive as such would reseat the rings in a tired engine.

    What, if anything have you learned or heard over your lifetime about helping out a tired engine?

    Old pistons
    by Chuck Sea/Tac
    im tearing an engine down, and it has ford .045" pistons with center lock wrist pins.my question is regarding the rings. The upper slot has a .012" spacer so it can use the same size ring as the middle slot. Yes, different size slots. The middle has one inch pieces stacked underneath the ring, so as to push the ring tighter to the cylinder wall. Whether these were originally one solid ring,...

    piston to wall clearance

    If .003 was too tight before, it will be too tight again.

    What is the advantage of putting sleeves in and going back to standard.
    by George Miller
    I under stand if you can not go bigger. But it sounds like some put sleeves in even if they have room to bore more.

    Pistons
    by DaWizard
    Well, got the pistons and con rods out of the block today as I am finished for now on the "craft shed" for the kidlet.

    Much to my dismay, none, nada, zip con rods have shims on the big ends!

    There is also something I have not seen before, pistons with not just one compression ring, not two, but three compression rings!! Plus the normal oil ring!!

    Now,

    If pistons could talk....with pix
    by tbirdtbird
    Pictured on the left is an old school Model A piston with an archaic design from the '20s, '30s, '40s.
    On the right is a Model A piston of modern design, a design adapted by all car manufacturers many decades ago. The skirt is short and the rings narrow. Inspect the features of the two yourself; you need not be an engineer. You only need common sense to answer the following 3 questions:...

    UPDATE on my engine troubles
    by Ray Horton
    Update for those who have helped with suggestions on my overheating problem:

    I took the block and pistons into Portland Engine Rebuilders today and told them they needed to hone to .0045. I explained that it all seems to have come down to the issue of the sleeves not transferring heat like a simple bore of the block, combined with the already questionable water distribution in the block....

    Ohio pistons
    by Chuck Sea/Tac
    a widow has an 1980’s set of .060” Ohio solid pistons. My question is, are they a good piston? Thanks.

    Valve seat cutter
    by pAAt
    I'm looking at grinding/cutting my valve seats for new style valves. What would be the proper grinder/cutter to buy ? There is also light pitting between the int. & exh. valves. Any help on doing this would be appreciated. Thanks, Pat
