I have two Subys, an '89 Coupe and a '97 Wagon. The '89 has the 1800 and the '97 has the 2.2 SOHC engine. I was looking for information on replacing the headgaskets (BOTH have BHGs...) and ran across this at AutoZone:
Also, on the 2.2 motor, notice that the head bolts are not covered by the valve covers! This is real interesting. However, i think for ease of removing the heads, it would make more sense to remove the covers to gain some additional room...
Looks like this might be easier than I expected...so why are people charging $1000-1200?!?!?!
