I can second most of the comments made already. I've had my 2000 OBW for 7-8 yrs. Has been fairly reliable with only major issue being the head gasket.
In this thread I'd consider Sackett the expert. I know the 2.5L engine had a lot of head gasket issues back in the 2000 time period. Was told by the mechanic I used that after the 3rd design of the HG, problem much diminished and I've had no further failures after that design installed. If you are going to have HG problems, typ happens around 125k miles. Typ HG failure will show up on driver side at rear. Major PM needed at 100k mi that includes timing belt, water pump and front oil seal. If you are a decent mechanic this isn't a big job. Some say use only OEM parts but I didn't and have not had any problems.
Not so sure you want to mess with the head gasket issue yourself as room is min for removing the heads due to fender well being very close by. Think pulling the engine is common for this repair.
Dust boot on front half shafts can go in the 125-150k range and if caught quickly, not a big job to just replace the boots but removing the shaft is needed. Oh, if you ever have to replace the tstat, use OEM part. I messed up and used a locally available high qlty after market part that resulted in engine over heating. Still had old part and upon inspection saw after market part had water passage that was about 50% of factory part. Oh, only use OEM radiator stop leak if you ever have to use any. Radiator passages are real small and typ stop leak will plug up the radiator. BTDT
Needed to replace cat converter at 150k mi. Qlty aftermarket part ~$500 and OEM closer to $1k
Never have experienced vibration as other member commented and not using any oil at near 200k. Local independent mech says engines are good for about 300k. If you have need for a mech, do find and use one that is knowledgeable with Subies.
