Default Blown Head Gasket...Blown Engine?

Hey everybody. So, I have reason to believe that my 04 wrx has a blown head gasket. It seems to be minor, but I haven't been driving it at all and I miss it. Recently after a conversation with a friend of mine who used to drive an 04 like mine, he told me that usually with bad head gaskets in these cars, there is usually a high chance that this is the end of the engine block too. I'm hoping this isn't true because I had just swapped this engine in a few months back and it is a fairly young engine from Japan. Is he correct? And should I start searching around for new engines? Or am I safe to just fix the gasket and drive my car again?

Why do you think the head gasket it gone?

Please be specific.

No, blown head gaskets do not always mean the block is bad or the head/heads are warped. It depends on how hot the engine was allowed to get.

I drove a fully blown head gasket 60 miles without killing the block or warping the heads. Very very frequent stops to refill the coolant and time to cool down. It took me over 3 hours, but I got it home with zero damage.

The best way to deal with a blown head gasket is to stop immediately and get it towed.

Well originally I thought there was air in my coolant system that was making me overheat, so I bought one of those spill tree funnels. But I noticed my coolant was constantly disappearing. When I went to burp the system, there were constant large bubbles coming up from the radiator. More than there should have been. My exhaust never really smoked, and I never had the burnt coolant smell in the car, but with the disappearing coolant and the air bubbles, I felt I was able to make my diagnosis. I do not believe it is extremely blown

That's a good indication that it's blown.
You can try a block tester to be certain.

As long as you never let it get very hot, the heads and short block should be fine.

You're friend is very wrong.

As Bikelok said, don't drive it and get it fixed.
Also, as Bikelok said, how hot did the engine get before you stopped riving the car?

I've heard of head gasket changes being done with the engine in the car, but that is a major PITA and the engine should be pulled.

I hat to say, but it did get pretty warm before I stopped driving it...

Well then, pull the motor and open it up. Look for scoring in the cylinders and have the heads checked for warping.

Good luck.

Update: ran a block test at a shop which came up negative for a blown head gasket. Still going to look into it further

Update: block test came back negative for a blown head gasket. Temps around radiator are looking funky. Possible that flow is being restricted inside of the core?

I've had a clogged radiator. My car would idle cool forever, but once I drove it it would get hot in 5 minutes.

Check the flow.
Check the thermostat too.

Thanks for the response. That sounds like my issue right now. If driven lightly, the car will not overheat, but if the rpm gets anywhere near 3.5k, the car will begin to overheat almost instantly

Default Head Gasket

I was driving from a stoplight today and just before I shifted out of second gear, Felt a sudden loss of power and the engine light came on. When I came to an idle it felt very rough like a cylinder misfire. I reluctantly took It to the Subaru dealer which was very close by. This is what they said:
"Mr Dom.
found the issue for miss fire on cylinder 2 and 3. valve cover is leaking oil,Engine head gasket is leaking,oil pump is leaking,and water pump is leaking. I got the price for the repair.$3519.05 for taking engine out,send head to machine shop repair valve cover,head gasket,water pump and oil pump(including spark plugs)
for the seat belt,i order the part and will be here next week.
also, did you know that there is a loud grinding noise from the transmission?"
The engine has not lost oil or water because I check regularly and there is no sign of any leaking on my parking spot. Does this sound fishy to anyone?

I'm not sure why you posted this in this thread and not create your own.

Anyway, go to your local regional forum and ask there for good independent shop recommendations. Get second/third opinions.
