Blown head gasket

how much would it cost to fix a blown head gasket for a 1995 gs? Where would be a good place to buy one? What would be the cause for a blown gasket?

It depends on if you want to do it yourself or have a shop do it. DIY will be cheaper, but it means you have to do the work. Pull the head, take off the IM, Exhaust manifold, all the sensors, TIMING BELT, everything... Then you have to put it all together. You can find them anywhere. Ebay has them for like $35 - $100+ depending on the kind you want. OEM ones are cheap.

IDK how much it would cost at a shop. I fugire quite a bit. Probably over $600.

How many miles are on it? You may want to get your water pummp and oil pump replaced too with the timing belt.

Hard driving, high compression, damaged motor, constant high rpms, driving fast, and just faulty can blow the head gasket.
