I may be purchasing a 2003 Legacy 2.5L L with the SOHC. Automatic transmission. It has 120k on it, and the owner doesn't have any of the repair records. His mother has owned it for the last 4-5 years and didn't have any repairs done. Long story short, it hasn't had the timing belt overhaul done, or anything from what I can tell. He says there is also a "small" oil leak that he "thinks" is from the front of the engine. It also has a salvaged title. I plan to test drive it and look over it with a fine tooth comb sometime between Friday and Sunday. If the price is right, I'll buy it. I'd like to pull the engine and do an immediate replacement of the necessary things. I have a bit of engine experience so I'm confident I can do it. I'm also confident if I do this overhaul this engine should last another 150k easy (notice I said engine, not the body haha). What should I replace on the engine, providing I get the car? Here's my current list: Timing belt kit from amazon including all idler pulleys Water pump w/OEM gasket OEM T-stat Front oil seals (2 cam, 1 crank) Oil pump? O-ring for oil pump? Rear main seal (since I already have the engine out?) Oil pan gasket Subaru Turbo EJ25 head gaskets Spark plug grommets Exhaust gaskets Intake gaskets Spark plugs?
*Added:
Valve cover gaskets
Adjust the valves
Resurface the heads
Tighten rear oil pump backing plate screws
Reseal the rear separator plate
Replace the access cover o-ring
Elbow "bypass" hose from water pump
Replace coolant hoses that go to the oil cooler if it has it
What else would y'all suggest replacing while I have the engine out? Is there something in this list that y'all wouldn't replace? I appreciate it!
