msmithmmx Posted July 4, 2007 Share Posted July 4, 2007 Question.... What is the difficulty level for doing the HG myself on a 2.5. I have done the swap (2.5 to 2.2) and that was not that bad. I need an idea of money and time for changing out the HG. Do I need to pull the engine to do the HG (does thet make it easier). What would you do.................

nipper Posted July 4, 2007 Share Posted July 4, 2007 Bigger questions.. year mileage on engine. Was the engine ever overheated, and if so how often or how long. nipper Link to comment Share on other sites More sharing options...
idosubaru Posted July 4, 2007 Share Posted July 4, 2007 mileage and condition of motor are important. if it's 225,000 miles and was run for a while with a blown gasket and overheated repeatedly....i would want a new block. if it's under 100,000 and was driven mildly and the owners were straight shooters, then the motor should be fine. there's good and bad both ways. i'd start with considering doing the headgaskets. if there's a convincing reason not too, then don't. the gaskets and machine shop time will run cheaper than a 2.2, you keep the original engine and don't have any issues at all to deal with. time wise, it's a wash in my oppinion, either way will be roughly the same. and air tools and an engine lift are more important than which way to proceed. time is affected more by rusted bolts, stripped exhaust threads, breaking parts...etc... if the engine looks clean and bolts aren't rusty that's good. depends what 2.5 as well, some have different vaccum lines and solenoids than the 2.2. i just found this out recently. even DOHC 2.5's have different solenoid and vaccuum set ups depending on..i'm not even sure yet, but i had to deal with it recently. but the 2.5 vaccuum lines and solenoid were different than other 2.5's i've had and the 2.2.

Skip Posted July 4, 2007 Share Posted July 4, 2007 Re: Do I fix the HG or swap the engine my mistake, I see by his subject he does question this. To me it did not appear as to a question of swap or fix, untill I reread the subject. I will delete my post as it does not truly pertain to the subject.

msmithmmx Posted July 5, 2007 Author Share Posted July 5, 2007 The car with the 2.5 blown HG has 200K. It was not over heated for long. I can get a 2.2 150K for under 400.00. I figure I can sell the 2.5 motor with busted HG for 300.00. Hmmmmmmmmmmmm Link to comment Share on other sites More sharing options...
idosubaru Posted July 5, 2007 Share Posted July 5, 2007 edit - i agree with nipper below - that's a lot of miles for a lot of work. Link to comment Share on other sites More sharing options...
nipper Posted July 5, 2007 Share Posted July 5, 2007 Il'd go with a replacmment engine. Replacing just a HG on ANY engine with 200,000 miles is a gamble on the rings. nipper Link to comment Share on other sites More sharing options...
