Post Cracked block?? Symptoms??

I have a '98 GT wagon that's about to go out of warranty...it runs fabulously, I think, but should I be worried?

GT Guy, My 98 GT Wagon has almost 85 K-miles on it and no apparent problems (except an alternator repl on "unofficial recall"). Previous owner was a bit of a fanatic about car care but I find myself enjoying the benefits for a change. Admittedly I've only had the car for a few thousand miles but if it holds up to my wife's daily grind and my more agressive style traveling (main reason for GT)it's gotta be a Subaru! Don't worry. Be Happy! oops! Did I say that?

Yeah, like he said. You can't enjoy it if you worry about it too much!

My car is a 98GT that had a crack in the #4 cylinder at @37,000. I think a minor problem, i.e. thermostat sticking, may have caused this problem, but I don't know. I drive the car hard and autocross it but the guys at the dealer and I both agreed that you shouldn't have a problem like that unless your cooling system isn't working. Here's my advice: First, if it's not to late get an extended warranty. SOA will even set up a payment plan on a credit card so you don't have to pay it all at once. However if you need a major repair you'll have to pay off the warranty before they'll pay for the repair. But at least you could pay off a $400-$500 warranty and get a $2000 engine or transmission repair. I only went 60,000 miles because of the money, but do the maximum mileage you can even if you go with the lower plan that only covers major repairs. Second, Buy a temperature gauge that actually tells you what the engine temperature is doing. And perferably mount it where it is easier to glance at when you are driving. If you have an RS you can get one of those wonderful gauge pods, If you have a GT like me, good luck. That's the only reason I haven't gotten one yet.

In any case I wouldn't worry about it to much. Soon the US spec WRX will be here and they will be getting wrecked so there will be plenty of engines to swap.

Um Subie Gal, are you saying the DOHC 2.5 L engines are bad??? I've got a '97 GT, 1996 build date. Is that a Phase I? I wish someone would list out all the 2.5 engines ever made and what the differences are (FAQ) ya know.

I am not understanding this either. Maybe I don't read the Forums enough, but now people are saying the DOHC Phase1 engines are crap? Hmmm, got 30K on mine, so far purrs like a kitten. My brother has a 98 2.5RS, he has about the same miles, but 24K of those are HARD turbo'd miles. No engine troubles.

I know 30K miles is not a lot, but this is all news to me. If Jamie damaged the motor in her car, I wouldn't panic. She drives that car HARD, a LOT. And breakdowns are something she could expect (as would anyone driving these cars under those conditions).

Hey Jamie! I haven't talked to you in along time! Anyways, I have a '99GT as well, but I have a Phase II block. According to a post by Trey Cobb a few months back, I checked my block. Starting in the MY99 some of the DOHC heads were fitted with the Phase II block... you guys may want to do a search on this... so far, I've had no problems... but that puny battery that comes w/ the car (420CCA)'s seems like my car doesn't start really easily even in the summer w/ 0w40 Syntheitic oil... It's time to get a Optima Deep Cycle 800CCA battery!

hey guys... relax...
here's the deal...

the 98RS engine = the 99GT engine
Phase 1 - DOHC

these are the engines that are notorious for *poof* blowin up... I had little/no warning. The car overheated 1 time... 1 time only... that was all it took...

if ya don't have this engine... i wouldn't worry...

if ya do... well...

ok.. yeah..
my car has a Phase I that's for sure... and i've NOT heard good things about the Phase I... DO A SEARCH... this has happened more times to this engine than we want to realize!

apparently my thermostat got stuck and that's what triggered the breakdown... only takes one time...

secondly... this happened at 50K - my car ran like mad up until this happened... and i drive the hell out of it... never thought this was going to happen to me... no "real" engine mods.. nothing to screw it up... just one of those things...

and yeah...

some research... engine types... etc.
would be good to have posted...
i'll even put them on my web site if you want...

Question

could someone explain how a stuck thermostat will crack the block? And also why a Phase I engine is more susceptible to this than the later engines? Is it something about the block or something about the thermostat? Also how do you know (temp gauge?) that its stuck??

-paranoid.

I had no way of knowing that the Thermo was stuck or going to be stuck.. I am not even sure that i believe the techs when they say this "may have" been the cause...

like i said.. search about.. ask questions...

the Phase I engine has really thin cylinder walls... this makes it more susceptible to over heating, and cracking cylinders and that type of thing.
Personally, as many times as it's happened, I believe it's a manufacturers defect. but... we'll find out.. as now i have yet ANOTHER Phase I block in my car...

I don't know of anything I or any of the others could have done to pevent this... it did not happen because we race our cars or have a turbo... or anything like that...

there was a great thread on this in the old technical forum about 1 month ago.
i am not sure if you can still search it...
i will try to find the link for everyone...

Well, the car is finally done. The dealer says that it was replaced under Good Will, and that the new engine is not under warranty, despite the fact I have 20k more miles left on the drivetrain warranty. Is this legal, can they do this? It doesn't sound right to me. Don't they have to prove that I did something and that something was the cause of whatever problem there was. Right now, I think it was a bad engine, and not my fault, but I'm being blamed for it, and thus my warranty being cancelled...is this legal???

Oh, yeah. While the car was there, they broke my Greddy front bumper apron. Not exactly a positive experience I've had so far.

Angry

make them fix what they broke...
and no they cannot void your warranty..

should be able to find many threads on this board about that...

my new engine is warrantied for another 12months... parts anyway... my 60K warranty will be gone w/in a month...

there is no way they can just void ya without PROVING you did something to the car...

who did you go to??
i'll help ya research if you want...

Question

Jamie- how come they didn't give you a Phase II block? Sounds like everyone's been able to bolt the DOHC heads onto that pretty easily.

Great, so there's no symptoms (until it cracks- could you describe that? big perf. drop?) and no preventative measures, so now I'm sitting on a time bomb.....

well not really sure why i didn't get a Phase II - ?? but they fixed it for free and with all the mods i have on there... i didn't wanna push the issue...

after the cylinder went...
THE ONLY symptom was that at idle...
the car would overheat....

that's it... other than that it was just as it always was... that's why i thought... "oh.. my thermo must have gone..."
but noooooooo...

just keep ya eyes out...
if your car even BEGINS to overheat...
stop the engine immediately...

i know that's not much comfort... but it's all i have to offer you... i see no other way i could have avoided this....
