I'm sure this has been addressed many times but I'll ask it anyways...

 

At what year was the 2.5L engine head gasket problem corrected? (I am assuming it was corrected!) --

 

Many threads. In general:

~1997-1999 DOHC - Internal HG leak. Requires new HG.

1999-~2002 SOHC- External HG leak. Requires additive.

The 2.5L dohc's 'phase I' had the potential internal HG exhaust blowing into coolant. These were used up to and including 1999MY, except maybe Forester got the phase II sohc in 1999MY; not sure

 

The 2.5L sohc 'phase II' have the potential external peeping leak until up ~2003.

Thanks for the info... I'll think I'll stick to 2.2's for now! 2003 is a little too new for me...

 

if '03 is too new , and you like 2.2L engines, you should keep in mind the 90 - 96 2.2L engines were non-interferrence.

 

97 - until, are all interferrence engines, t-belt, water pump, idler, or tensioner failure equals head / valve damage. so add the cost of a t-belt replacement to any '97 - until' car unless you know for sure when the belt was done. if you don't know when it was done you should do it sooner rather than later. waiting could be expensive.
