Hi. I have a 2002 camry 4 cylinder. Long story short, I was driving, termostat blew ( cold air instrad of hot started to blow) , needle started going up and down from middle to H . At no point did I see smoke coming from engine. When I pulled over, antifreeze area was cold and silver piece in front of engine was cold. Since I was far from home, kept driving , needle was going up and down. Eventually, as I was pressing gas, car was not accelerating , was staying around 40mph as I crossed whitestone bridge. Slowed down to pass ez pass and 5 seconds later, entire car shut off . All of the lights came on (battery light, oil, everything). Had to be towed. Mechanic only told me that the car has no compression. Claims that becasue engine has no compression on any of the cylinders that the engine needs to be replaced. Should I bother towing around for a second opinion or does this seem right? Trying to decide if its worth fixing or if I should junk it and get another used certified car.... PLEASE HELP !
Need more information, but you do at least need major engine work. Perhaps the head can be repaired, might need a new head, might have damaged the block. Only a more complete diagnoses and/or tear down will determine for sure. How many miles on the engine? If it's high mileage, probably not worth rebuilding the top end. Rebuild the top end on a high mileage engine, and the next weakest link goes next..
Many factors need to be determined... If all four cylinders are zero, you did some heafty damage. Perhaps they were just low, and you're saying zero...?
Question is "just how hot did it get"? Hot enough to blow the head gasket,yes Hot enough to burn out the crank and rod bearings and melt pistons maybe...YO when it gets hot the first time STOP..No aluminum engine can run "hot" long and can be only a matter of seconds before damage is done.

First, it's not likely your thermostat blew.
What's most likely is that you had a blown head gasket. Without knowing it you ran all the antifreeze out of the car. That is why you had cold air instead of warm blowing inside the car.
Unfortunately, you kept driving the car with no coolant in the engine. Most likely, you ruined the engine by doing that.
From here, you're probably facing the decision of whether the car is worth fixing, or whether you should get a different one.
Yep, this engine has been well "cooked". It's dead.........

While cheaper a used engine is a poor choice in 99.9% of all rebuilds unless you're building a demo derby car. Why pay for the unknown when a Jasper rebuilt engine is very well known and with a warranty to boot.
I've never seen any sort of a warranty on a used engine in all my 63 years. Hell, a used engine isn't even warranted to run so why buy one?

Well... 6 years ago I bought a VW Golf on an abandoned vehicle auction. Turns out the engine was toast. So I bought a used engine from a salvage yard in Lincoln, NE. It had just under 50,000 miles, and I paid $325 for it.
I installed it myself, and have been driving the car since. 100,000+ miles later, I think I did alright.
That's just one example.
