  • Engine: Oil Pressure 'plunger valve' direction; I assume the way it WAS is WRONG?

    Looks to me like yet another "mis-assembly" by whoever rebuilt this 289 V8 last (57 GHawk). But, as paper catalog drawings can be misleading in 'sizes', thought I'd confirm.
    The photo is how my plunger/oil-valve (up by the timing gear cover) looked when I removed it to rebuild the engine. (AFTER the guy I had machine the block, etc... cooked the engine; sigh..... Yes, I took apart the valve rocker-arms and cleaned them after I saw this, too! If you want something done right.......)

    Anyway, note the SMALL hole in the plunger is facing OUT, as assembled in my engine pre-rebuild.
    In Shop manual, it REALLY looks like the larger diameter hole should be facing out, and this is how I put it back in today.
    Please correct me if I'm wrong, and the tiny hole really SHOULD be facing out like shown in the photo...
    Thanks!

    The hole goes in. Yours was assembled wrong.

      Thanks Roy! Nice to confirm.
      (One of these days I'm going to get that rebuilt radio you did for me out of the basement and IN THE CAR where it belongs! :-) Have all the parts, chrome, upholstery.....; lacking the time!)

        you should wait until after the car has been painted. The sanding dust gets into everything and damages the electrical components.

          yes indeed! My plan (a few items in line first I'm afraid) is once I finish the chassis and get the engine in, choose my body shop and painter, get some gold paint from them, paint the engine compartment and underside of body, then mount the body and reassemble hood, doors, trunk lid.... , weld on the rocker panels FINALLY.... and then have it hauled to their shop and "paint the rest". Install steering, seats, glass, everything else after it comes back.
          So NONE of the interior or trim (or radio!) will be installed when it's painted. Or thus is the plan at this point. :-)

            Good plan, plunger small hole end goes in first to meter oil to timing gears at idle and lo speed before oil pressure bumps plunger open to regulate pressure. Good Luck, Doofus

              This must be one of those ASE Certified "Mechanics", I have met a few here and in person who could not assemble or understand how a Car works if their LIFE depended on it!

                Yeah, pretty frustrating; I worked through ONE rebuilder, who then farmed each piece (Block & rods; crank; cam) out to specialists, so NONE of them got the Shop Manual I brought up for "him" ! :-(.. The silver lining is these other three guys are all excellent machinists and build race car engines. So, from what I can tell, the crank, cam, etc... are all beautifully done, spot-on repeatable dimensions.... but the unique Studebaker parts tripped them up. I can forgive the 'reversed' connecting rods on one side; no shop manual to reference and hard enough to keep straight with shop manual at my side! But I AM surprised that guy did not clean out the rocker arm mounting 'tube' or remove that oil pressure valve by the timing cover (it was the only other not-cleaned part. Again, he wouldn't know what direction it should go either without the shop manual if he wasn't familiar with Studebakers. (again, the ORIGINAL guy I took it too is the one who had done some Avantis and such, which is why I took it up there; just didn't know he would farm out everything and make it a a non-issue!)

                At least he DID take out the oil-chamber plugs; fresh blue RTV around them.... (and the one behind distributer galley) and ran a brush through, he said. AND, his machining looks excellent.
                So, an extra week correcting /rotating the rods, new pinch-pins , and popping out the plugs on the rocker-arm shaft and cleaning that up, and I think I'm good.

                Now the FIRST guy who rebuilt that engine (years ago but not many miles, and still ruined it; should see the bearing inserts and the grooves!), he's the one I'd like to have a nice long chat with! The pulleys were even assembled out of order (for steering pump, supercharger, etc.) are out of order (I still don't know what the correct order IS for the spacers, manual doesn't show for a 57 Golden Hawk with Supercharger!)
                DOES ANYONE KNOW WHAT ORDER THE PULLEYS AND SPACERS should be in for a Golden Hawk, with Power Steering and Supercharger? Honestly, manuals don't show as '56 didn't have supercharger, and 57 supplement ONLY shows the supercharger pulley and MENTIONS "spacer". I don't know if different sequence OR if I'm missing a spacer (ie: need another one for the Supercharger). Maybe that is why the Supercharger was in the trunk when i got the car. ;-)
