I should have tried that too. I never thought about the Super 300 sealant. My 235 ran fabulously, but it leaked like that too. I changed the head gasket 3 different times before finally giving up and sadly removed the 235 motor.
...I never thought it could have been my choice of sealant.
I always thought maybe the block was warped. Because I even tried having my head shaved perfectly flat by a machinist.
Man...if I only still had that motor. I would have tried a 4th time with that Super 300 sealant.
