We dont call them well used, when it comes to subaru, we call them "just broken in"

WHen you have the Headgasket job done, the first thing you do is have the heads seant out to be rebuilt. The surface is remachined to the proper finish, then if necassary, also restored to the proper flatness. Also the heads are rebuilt which means a valve job. Between these two you are restoring and or increasing the compression to factory specs on 1/2 the engine. you have done nothing to restore the deal at the rings to refresh them. On a high milegae engine (which this is not) everything wears equally. Just rebuilding the heads and losing some material can push the compression up to where the rings may have blow by. If you are doing a HG job without resurfacing/refinishing the heads you may as well throw your money down the toilet, as it is only half a job. So yes it will raise/restore compression form what it was before the HG job. Just speaking form my 20 years of pulling a wrench and many years in the auto engineering field. nipper

Looks like Subaru's evil overlord isnt so evil
nipper replied to nipper's topic in Non Soob Cars and Bikes Discussion
Because its supposed to be a cheap RWD sporty car. RWD is actually cheaper to build then FWD, and it does have its advantages. nipper -
The reason i ask is because when you do HG's on a high mileage engine, you raise the compression slightly. If there is over 160,000 miles on a sooby, I try to stear people to another engine. I dont want to hear that they are buurning oil, 100,000 Km = 60,000 miles ? Also if the engine has been overheated repeatedly a compression test will tell if the cylinders have been scored, as all of them would be scored if the engine was cooked. It sounds like you should be OK. Remember to change the oil after the engine is all together.

WOW holy siezed engine batman. An entire qt? Somehow i dont think that has any real lubricating properties. ALl that does is swell the material the seal is made out of. It is almost impossible to seal a rotating seal once it starts to leak with a simple additive. nipper

The newer is a little heavier then your old one nad has larger tires. Also i do believe it is drive-by-wire which do have a lag for fulll throttle (it's getting better and toyota was the worst). The best way to deal with it is to manually downshift if you need full throttle. There may be a re-flash out there for ecu/tcu but I cant seem to find one. There may not be much you can do about it.

I would make him an offer and snag it. SUS's are so hard to find. It needs a valve job most likely. The TB change was probably because the engine was running a little off, and they may not know the history of the car, so they blamed a loose TB. Lazy or underskilled mechainics can make bad judgmensts sometimes. nipper
