Head Gasket - who should repair?

A new way to clog all the tiny passages.... nope.... it's crap.
None of that crap works. It will seal ALL the small passages....

It's your engine, and radiator, and heater core, etc....

 

Yeah if you use the stuff from 20 years ago. But whatever - it's up to him.

 

NONE of the head gasket sealer is good. It's ALL bad.
It just does NOT work. It "clogges". ANY passage.
The ONLY way to "cure" the bad head gasket is to replace it with a new one.
And have the head check and hope it's not warped.

Like putting thicker oil in the engine. It is NOT solving anything. It's just masking it
and making it worse.

 

The sealant goes in the coolant, not the oil. It often seals Prius early head gasket leaks for 4 to 16 weeks but will ruin the heater coil and radiator. If you use the right stuff and flush it out repeatedly after 400-500 miles. It will almost guarantee the engine will have to be replaced.

 

Isn't a JDM engine replacement from a vendor who gives installation and warranty a better solution and cheaper too ?
