Default What would you do? - help with HGs

Im lookin to perhaps upgrade my powertrain. I have a 97 outback with the EJ25 that has its HGs going already.. . looking to do a new motor but not sure what to do yet... any suggestions? to get my HG's repaired, ive seen that it will cost up to about 2200 dollars to get both HG's done at the dealer. I am unable to find other places around me to get this done. Think i could do an engine swap for about that same price with my own labor? any comments or suggestions? Would getting both HGs fixed be worth the 2k or so ? 1 HG will run me 1500.

My HG repair was around $1500.

For $2200, I would rather invest a little more and buy a new engine. If you do the labor yourself, depending on the engine you select, it might be in the same ballpark.

i just went this route in fact. I bought a newer 2.5 SOHC motor but there were some install issues so i ended up selling it for what i paid $1400 and just repairing my HG's myself. it seems a daunting task, but its pretty easy and parts will run you $300-600 depending on what you replace. i replaced my clutch and waterpump while i was in there.. and all the gaskets. the reason the repair is so expensive is the time involved. i was kinda lazy and only did work on the weekends and it took me a month. but i know i could have done it all in a long weekend if i wanted. I pulled my engine and its the best way IMO

Is that necessary to have done? how much will that run me? Has everyone else done this . . or just the gasket kit ?

yup.. aluminum heads tend to warp/crack when overheated... but its up to you to take the chance that they are "Fine".

Default :-( it finally happened.

Well it looks like it final happened to me yesterday. My cars temp gauge went up to H and my air blew cold, and the res. was overflowing with coolant. So ive come to the conclusion that my HG's are under way. I believe its because in the compression stroke that its push air into the coolant line, causing a 'block' in the system, so coolant exits but not enters basically. Well I found a place to have both HGs done with water pump, timing belt, and heads done for around 1100. So im taking him up on the deal and wont see my car until next week. . . but atleast it will get done.

Should I have anything else done while he's fixing that?

ALSO what specifically did you guys have done to your heads? just machined? or new springs and valves and such?

t.i.a.

if he's doing water pump, you might as well have the timing belt done.

Have him do any other gaskets that he can while he's in there.

To my knowledge, the previous owner who had the HG's go at 173K had the heads machined and all gaskets replaced; I don't believe any new hardware was required.
