    Changing Timing belt, what else should be changed?

    Hey everyone,

    I'm about to get some maintenance done, i just hit 90k on the original belt. I have been running the car hard lately and don't wanna take a chance of the car dieing on me, I got the following ready to be installed.

    Timing Belt
    water pump
    tensioner
    crank shaft seals
    main bearing seal

    is there anything else i should replace while in there?
    Thanks

    If you see any juice coming out then replace that part. Also replace the external accessory belts, using authentic Subaru items.

    +1 ^..Take a feel of all the idlers and if any of them feel rough or are questionable..replace it. ( Of course some people prefer to replace all of them anyway while there in there, also considering this is a highly interference engine )..Also I was going to mention all 4 cam seals, however that may be what your referring to as the "crank shaft seals"..And the 1 crank seal which you may be referring to as the "main bearing seal"...Also It prob wouldn't hurt to remove the oil pump and tighten the backing plate screws ( they have a tendency to back out sometimes) reseal the pump, and replace the o-ring...

    Easy is such a relative term. I'd say feasible, but then again I am not mechanically skilled. Here is what ended up happening on my car in the link below. I got extra vise grips and used the old seals backwards to hammer in the new ones. A bunch of o-ring picks got broken removing the old seals.

    Cam seals, crank seal: Replacement? How?
