My Project Cars



Found 2 results

  1. The car - 1949 Wayfarer with the 230 flathead 6 of course.... Car had been sitting for two weeks before this was found, drove normally before with no white smoke from tailpipe. Radiator slightly low, but not drinking coolant at an alarming rate. I removed the carburetor for a rebuild last night, and what do I see pooled in the intake manifold? Coolant. It looks like the coolant is originating from the runner that feeds the center two cylinders (3&4). I pulled the spark plugs, all look OK (slight rich, but not steam-cleaned). All valves that I could see also show normal operating conditions. I understand that most manifold studs pass into water jackets, but am not sure about head studs. Is it likely that I somehow have coolant seeping past a stud and pooling in the intake manifold? Or maybe a cracked/misdirected water distribution tube? Or does anyone believe this could be something more severe, like a cracked block? All input is appreciated. Thank you.
  2. I'm completing a total rebuild of the engine, but my problem has been coolant leaks. The two longer manifold studs leaked. One of the water pump bolts leaked. And one head bolt leaked. I've solved all those problems using aviation gasket maker but I have one more leak that has me more concerned than the others. I'm somehow getting coolant in the oil. When I cracked open the drain plug I got a stream of coolant, maybe an ounce or two, before I saw any oil drain out. So now I've taken the front of the engine apart again. I gave the welch plug another good smack with a 13/16 socket for good measure. From what I can tell the real problem is water getting past one of the timing cover bolts and soaking through the backing plate gasket. Initially I used aviation gasket maker on the timing cover bolts, but I did not smear it on the gasket. When I reassemble everything I WILL generously coat the gasket and smear the female bolt holes with AGM before I coat the bolts and insert them. Other than timing cover bolts and the front welch plug, is there any other way for coolant to get into the oil? Is Aviation Gasket Maker the best way to seal the threads or is there a better sealant? I think the hole next to the welch plug leaked.
