Ceramic coatings not ot

[Frank Elder]

Young Ed has posted an interesting build on the truck side about a 40 Dodge car hauler build. The most interesting part to me is that the owner keeps making references about having the water passages, jackets, ceramic coated to ensure better flow in his 331 six. Both in the block and head this sure would keep the crud from building up.

Has anyone everheard of this process before?:confused:

it is a very complicated process...cleaning the passages in a used block would be very hard to ensure that the ceramic coating would adhere...nooks and crannies that has corrosion would be hard to get to...caoting this surface with ceramic is also a iffy situation..once coated, it is a multiple heat/cure process where 600 degrees must be maintained..

cast iron is porous...it will leach through forom one surface to the other over a period of time..look at you cast iron skillet...you cook in it..you take care to wash it..you do not splash oil when cooking (confirmed by lack of grease fire) but yet the outer surface is covered with caked hardened cooking oil...the only way to get rid of this oil is to completely burn the it off in a bed of red hoat coals in an outside fire..this will burn the surfaces clean and render the oils in the metal out ..I cannot see how you could duplicate this precess on an "used block" or component to ensure the ceramic coating which by the way is very thin and guaratee the coating will not blister peel or crack..just one crack can cause failure...when bolting metal to metal..would be hard to say this would never happen..looks like a waste of time and money for a process that could be avoided with proper use of coolant winter and summer..

I am ignorant in this area but my impression is that a ceramic coating is a bit of a thermal insulator. (Same thing for most paints.) So why would I want to put an insulator between the metal I am trying to cool and the coolant that I am trying to get heat into?

My take on that is - the man who owns the truck, and whomever advocated doing

the coating, both think that ceramic is tough and slick -- thereby making the coolant

flow better and probably reducing or eliminating crud deposits.

But, did they think or know about the things mentioned above???

I suppose time will tell.

My thoughts exactly.
