Okay, first off, yes to your question at the end....
Second, You might not have to pull the cylinders....or the engine.!
I think all you need to do is pull the problem side, and replace the green
o-rings, the metal head gaskets, the black rubber gaskets and head nut
sealant... Read Boston Bob's essay on the job. (on his website). The
black o-ring at the base probably will hold up.....Not a huge gamble either
The reason, I think, Your coolant isn't getting sucked back out of the
overflow tank is because of the air in the system and leak in the head. So,
remove all the stuff around your head, drain the oil and the coolant, yank
the head (careful with the stuck cylinders), get the head serviced
(optional)--inspect the surfaces for pitting, replace the orings, replace
all the other gaskets with sealant on both sides of rubber, replace head,
TORQUE to SPECS, put engine pieces back on. Start-up and bleed coolant
Oh, back up, adjust valves to .006" lash. Don't follow Bentley. Follow
Boston Bob's article.
after all that, if it doesn't work, THEN yank the engine. But that should
do it, if the coolant was in the cylinder, not the crankcase (i'm sure
there's a little in the crankcase from slippping past the piston.)
Good Luck, happy trails, replace the water pump too.
