There are "head gasket fix" additives you can put in your antifreeze, that you can buy at the box stores. But no one will recommend them. They are a band-aid to possibly get you home, 1 time, AT BEST.

If you can't afford to do the head gasket right now, can you afford a new motor tomorrow?
Find a way to get it done, or park it.

My brother tried this stuff in his old Toyota Camry. It extended the life of the car for a few months and then it expired.



I would not recommend it on any car you care about.

If you can afford a couple of tanks of gas for your Corvette, you can afford to replace the head gaskets.

A set of head gaskets, GM TTY head bolts, and stuff to clean the head and block surfaces can be purchased for less than $100.

You can do all the work yourself in a day. The only special tool you need is a torque wrench and you can rent one of those at any autoparts.

And even if you have never done any auto work, this is a great opportunity to learn. Plenty of how-to's online for this and plenty of people who are willing to help with questions on this forum.

Sell it, but will have to tell the new owner about the gasket OR now you have the motivation to do the work.
Take your, maybe find someone in the area to watchover the work.

Do you have a second vehicle? If so park the vette until you’re ready to fix the head gasket.

I put this in my girlfriend's PT Cruiser last summer since it was way too hot to do a head gasket, it stopped the bubbles that I'm guessing were exhaust gasses entering coolant, also stopped overheating immediately, lasted from June to right before Christmas, however it clogged the heater core and when it got cold I had to use water hose to purge out heater core.<br/><br/>Then water pump started leaking and because the PT Cruiser is so tight to work on, I told her time to get a new car.<br/><br/>

Is there coolant in the oil ? If not it's possible that the leak may be coming from one of the steam port connections (there are (4) total) in which there are (4) O rings that given the age of your car, can go bad.
The proper way to determine a coolant leak is a pressure test.

Time for a 2nd opinion.

Why does the engine need to be pulled out, just for head gaskets?

Go to another mechanic. The engine does not need to come out to replace a head gasket.

As for those coolant fixes, they are trash as was previously said.

Save some money, and get your car fixed by a mechanic that knows what he is doing. Or learn and fix it yourself.

If you put any type of coolant sealant in your car and then drive it, you will end up needing a new engine.
