Re: Subject: 90Q20V coolant

My 1990 90Q20V consumes coolant. Take it to the dealer, they top it up, and 
send me on my way. No leaks, good compression, changes overflow cap, any ideas?

My experience says maybe a bad head gasket.  Coolant leaks into cylinder & goes 
out with exhaust.  Check spark plugs to see if wet.  Also might be evident as 
white smoke out exhaust.  Big nuisance, big bucks.  Must disassemble half the 
engine just to change a $10 part.
