is my 1999 impreza outback sport 2.2L (135,000 m) at risk for the head gasket problems commonly associated with some older subarus?
not likely, the 2.2L enigines have very few issues with head gaskets, usually it's on the late 90's early 2000's 2.5L where you start to see head gasket issues become more common.
Nice that defetive materials don't last. They are switched or recalled immediately to avoid litigation.
I have a 2001 2.2 L and a 1997 2.2 L with 205,000 and 195,000 respectively without any head gasket issues. You should be fine for a long time so long as you are keeping coolant and oil levels appropriate in the car.
No, the 2.2 does not have the headgasket issues found in the 2.5 liter engines. (and a bonus, the 2.2 is NON interference, unlike the headgasket blowing 2.5 liter). Properly maintained, the 2.2 is an honest 300k mile motor.
Actually, only the phase 1 2.2 is non interference. The phase 2 2.2 made in 98-99 on up are also interference engines.
