Coolant ingestion
 

1986 Accord, 225,000 miles.

Left home a week ago, all seemed normal. After a couple of miles, I noted
no heat and temp gage still on Cold. Then I noticed white smoke in exhaust
behind me. I stopped and refilled radiator and drove 4-5 miles with white
smoke the whole way.

Pulled the plugs and cranked it over and water was spraying out #4 spark
plug hole. Drained radiator and checked compression.
#1 150 psi
#2 140 psi
#3 170 psi
#4 150 psi

I'm guessing that the head gasket is blown, but if the head gasket is
leaking that much coolant, would I still be getting 150 psi pressure on that
cylinder? Any other diagnosis for these symptoms?

With the age and mileage on this car, I don't want to spend much. I was
planning on pulling the head, replace head gasket, timing belt, and water
pump and hope I get another couple of years out of it.


TIA
