To correct your first sentence: a theory is not a fact. Steam formation is a fact-it is NOT 'highly likely' in my and apparently the forum's experience. Blown gaskets reported here are virtually all caused by improper gasket choice/construction/installation, poor machining or porosity of block or head surfaces. The gasket breach causes the coolant (or
oil) loss which then could cause steam formation. NO coolant will prevent that once the gasket is breached.
I'll make this is as simple as I can: I do not deny that these scientific occurrences can exist. I have had the experience that in 25 years of driving and racing the same Cobra with two different engines and states of tune-that I have not had ANY such occurrences. The group of approximately 40 other Cobras in my region have had no reported failures of head gaskets or pre-ignition related problems. Nor have any of my street cars suffered these failures in 45 years of driving them.
The primary causes of pre-ignition are improper timing and poor fuel. We've all figured out how to avoid this. As has the majority of this forum. Yet you and the Professor continue to pontificate on the ease and frequency of these dreaded failures.
So like the OEM's and most aircraft users have figured out-there's no
practical need for this 'savior' coolant. It may be a neat scientific chemical but I have repeatedly stated that what I've used for decades has served perfectly-and my standard-bore block is NOT a moth-eaten rusty hulk because of these materials.
I really hope this horse is dead now.
