hey blade another thing you can do to get your compression back up ( other then installing a ford) is squirt a little oil in each cylinder cause if you've gas washed the rings it will take some time to get it back up to par otherwise let it sit for a day or so and let the gas evaporate slowly, and i would put money on it that is where your getting the gas in the crankcase for ive had it happen to me years ago on my first ???? do i dare say cccchhevy

there i said it .
