If you think the issue is a blown head gasket preform a block test for exhaust gases in the coolant.

Given this is the second engine with a problem have you check the cooling system, plugged radiator, etc?

Some sealants and cleaners also have effects on the radiator as in plugging it up.

 

I always do this whenever I think I got blown gasket...
and it work... it sometimes blown gasket most of the time it's not.

 

thanks I will have it checked is there any outher reason for the bubbles?
