Default Questions about coolant in oil

I have an 04 WRX with about 83,000 and i believe that there's coolant in the oil. Could this mean a blown head gasket? My car isn't over heating yet, so i really don't know. Just in case it is a blown head gasket i called the subaru dealerships around my area and they want anywhere from $2,000 to $2,500 to replace it. I feel that that price is outrageous. One of my friends suggested to use block seal but i really don't feel comfortable doing this cause it seems like a cheat alternative. Cause like they say, "You get what you pay for..." Is the block sealant safe?

Any suggestions of what I should do??

Is this an automatic or a manual?

I was a mechanic at a honda dealer before getting trained and going to UPS as a diesel mechanic.
How do you know there is coolant in the oil? There are obvious signs ansd ways to find out, but do yourself a huge favor and do a UOA that cost under $30.00. You should stop driving your car if it is leaking coolant in the crankcase.

We did use block sealer a few times at the honda dealership as a last ditch effort to save the car from the junk yard and save the customer some serious money. It seemed to work. On a WRX or a boxer engine, I wouldn't do a head gasket, but would do a cracked block or head that leaked slowly.

If you do not follow the direction of the block sealer to the tee, dont bother as it does not mix with coolant. Confused?
Pulling an engine from a subaru is rather fast & easy with experience and the right tools for the job. You might find a local mechanic who can do the job for much less using OEM parts.

what makes you think there's coolant in the oil?

does the car consume coolant? is there oil in the coolant? there should be if you've got a blown head gasket since oil pressure is going to be higher than coolant pressure. make sure its not just condensation you're mistaking for coolant before you throw all this money at it.

$2k is a reasonable price. Just get it fixed correctly.
