  • Main bearing oil feeds

    Readjusting valves on newly built engine. Noticed when I pulled valve cover off, oil went everywhere. The center valley was full, but not the ends. When I put oil down the end main feeders it drains, but the center main does not. I know the feeders were flushed. Which is normal? about a half hr run time over several starts in a stand. I thought I had a tappit noise, but now thinking it’s the center main because of lack of oil.

    babbitt motor? if so maybe some clay stuck in the feed hole at the block journal, or other debris. who was the rebuilder

    Clay is used to block the feeder holes to keep babbitt from going in there

    feeders were flushed at what point in the build sequence?

    You may want to contact the builder because if the hole is blocked in the block the only way to clear it may be to get the crank out, which means a motor pull

      Is the engine in the car now?
      This doesn't sound good and I think I'd pull the pan and center main cap to check the babbit.

        Center Main
        by Jerry Kzoo
        Guys,
        I was having an issue with a Babbitt motor and thought I would investigate since we are in the middle of stay at home orders. It would have a knock at start up after sitting for a month that went away after 30 seconds or so. When I took it all apart the center main had a lot of wear on it leaving a larger than wanted clearance there. I removed the remaining shims and reassembled and...

        I am in the process of cleaning any sludge and old oil from my A’s little motor. Dropped the oil pan and I guess I am missing the rear main cap drain tube. Yikes...

        Oil grooves
        by Hazelhoff
        I have tried this on ‘another Model A forum’ ... but ... you know !
        I’ll try it on this very serious forum for a change. For a couple of months now I find myself being annoyed by the presence of the famous spiral grooves in Model A Babbitt bearings. I can understand someone adding some sort of oil groove in the upper half of a crankshaft bearing - helping distribute the oil - but never...

        Oil Leak, just asking
        by Jackc
        Okay, I know," if it's not leaking its out of oil." BUT, after driving I get a medium sized puddle of oil out the flywheel cover (cotter pin).
        I have removed the cover and run it, looked at the rear main (dry), checked the pan bolts, and verified the oil return line on the block side is not leaking.
        I am thinking the cam gasket, but wanted to see if anyone had other ideas before...

        Significant oil leak
        by Tom Rode
        So I've been driving this car a week or two now, parked in garage it leaks no oil, go for a drive and come back and park it on driveway and it drips oil from the weep hole in the bell housing for 5 or 10 minutes after I return. Clearly leaking while running. Read some about clogged oil return line from the rear main bearing, and other issues regarding leak at bearing and/or seal. Have read other sources...

        Valve lubrication, or not!
        by DaWizard
        I have been seeing folk getting all over MMO and questioning the reason for using it. Well, I think it is time to clear a bit of air within these airheads and explain why MMO or Seafoam, or these top end lubricants are almost a must.

        If you will take a look at this picture of the valve chamber, you will see to the right a copper tube protruding from the bottom of the valve valley. Well,...

        by Adog
        Just bought a new to me 1929 model a pickup. Engine runs fine with no knocks. After a 20 minute test drive and parked on concrete, oil flowed out of flywheel housing. A area approximately 18 inches In diameter. Oil also leaking from left side of engine pan and base of oil fill pipe.

        I have all of Les Andrews books. Question, is it possible to remove pan and the rear main cap for inspection...

        B crank in A block
        by Greynomad
        I am looking to build a strong, smooth running touring motor preferably without having to spend the big $ to buy a new crankshaft (about $3,500 by the time it is here) and I've have heard of people grafting a counterbalanced B crankshaft into an A block but I haven't seen any details on it. Has anybody out there done it or know anything about it? I have a crank and rods ready for it.
        I see a...
