    Oil in coolant

    Oiling is stock and I have a sealed water pump. I may flush the system and try it again before tearing it apart. Winter season here now so I won’t be driving it for a while. Most of my driving is a short drive to town 5 miles away. Towards the end of summer I was doing some 50 mile and up...

    Oil in coolant

    I used a Best brand head gasket with copper coat. When I think about it there are no oil passages in the head gasket area. The pressurized oil is in the cam area. A crack somewhere is what I’m thinking. It’s funny coolant does not go in the oil. I drained the coolant into a small container then...

    Oil in coolant

    I drained the coolant out of my banger today and there was a substantial amount of motor oil in it. I drained the oil also and there was no coolant there. I drained the coolant this summer to pull the radiator to install a harmonic balancer and there was no oil in the coolant at that time. So...

    Damaged Babbitt

    There were shims in the front cap all others there was none. All of the journals look nice but measure under size.

    Damaged Babbitt

    I disassembled the engine on my A and found this broken bearing, front of the rear main cap. Other than this the rest of the bearings look good. I assume there is no repair to this?

    Spreading frame to install engine

    I have a spreader. I’m curious if the amount of side force effects felt vibration on the engine. And how much spread needed to install is normal. Are all frames about the same? I am installing new rubber pads and bolts.

    Spreading frame to install engine

    My frame needs to be spread 1/4 inch to install the engine on my A. Is this tension part of how the side rubber mounts work? Is there such a thing as too much tension?

    Are the rear radius rods bolted solid to that new transmission bracket? If so how can the rear end articulate?

    Model A rear tire size verses cruise RPM

    I am running stock wheels. I was using a different calculator. A gear change to 3.54 would yield around a 147 rpm drop. So if the next size up tire 6.00x 19 comp H is truly a 31 inch tall tire from the 29 I have now it would yield about the same rpm drop. Has anyone ever measured a 6.00 or 6.50...

    Model A rear tire size verses cruise RPM

    I have a stock 31 A Tudor with 5.00x19 tires on it now. I would like to lower the overall RPM at cruising speed by changing the rear tires to either a 6.00 or 6.50. In stock form is there enough power to use tires that size? Eventually I’m adding a different head and intake. I’m running...
