Head Gasket for Pt Cruiser

You're looking at a sub-$1,000 car, maybe even half that, the mileage kills any hope of getting a decent price out of it especially as a "mechanic's special," so you might be better off scrapping it, unless you want to try replace the head gasket yourself, and drive the car the rest of the way into the ground, lol. It can take a long time to part out the car, but you might get lucky, you want to pull all the body panels and store them, especially doors. Dont sell pieces and parts off the doors either, sell them whole - glass, trim panels, window regulator, etc. Sell the door as a complete unit, otherwise scavengers will pick over it removing some minor part leaving you with an unsellable door. Sell the seats as a complete set as well, there's a reason why dismantlers sell complete sets of seats as a unit, cause if they sell one seat then they're left with a broken set they can't get rid of. Parting out a car isn't going to make you rich but it makes you more money than just selling it for scrap.

Head gasket sets for your car are around $80, a Service Manual for $20. If you're adventureous you could try to fix it, after all your other option is maybe scrap it.

Then you could just buy another engine at a scrap yard and install it with help. My vote is to part it out unless you really like the cruiser. Get another one and be happy. 214 grand is a lot of miles.

Blue devil the sh*t out of it

Blue Devil it and if that does the trick then drive it till it dies for good then strip the parts for mercury ( catalytic converter, radiator etc.) cuz that stuff is worth decent $ at scrap metal lots then take out anything else of value but I own a 06 and there is not much value in that model car so I'd jerk the tires and haul it to the crusher and sell the hull. They are junk really and I wouldn't own another one gonna sell this one to the 1st person that has my asking price. Buy something else next time I know I WILL. Good luck!
