Fairly new to motors but I was wondering (if it's even possible) that a ceramic coated block would have any pro's con's to performance??? I don't even know if the coating would stick to the block much less if it would help the motor, but this idea just popped in my head and I don't think I've ever seen one coated (probably for a reason). I'm a creative person that likes to spitball ideas... sometimes the ideas are good... other times there just down right stupid. This also goes for chrome, nickel or any other coating. Is anyone doing this... is it even possible???
This is my theory, but putting ceramic coating on exhaust headers works well because it stops the actual header from heating up as much and forces the heat out the exhaust instead. Ceramic coating intake works well because ambient heat can't travel through the intake as much and heat the incoming air. Coating the actual engine block itself would not be beneficial because if you coated an engine block it would cause the heat to be retained in the block, which I don't think you would want. Does this sound like a valid theory?
The theory behind coating is that it keeps the heat in. Hot air is less dense meaning it will flow easier and the scavenging is better with coated exhaust. It helps on turbo applications because it carriage heat to the turbo and heat is energy. I think the only thing that would happen with a block being coated is you would get the fake chrome look. I can't see it slowing the cooling efficiency if the engine at all.
Coating would hold heat in and raise the chance for overheating. Dirtbike manufacturers tried it in the 80's and it caused all sorts of problems.
I have no scientific BS to back up my opinion..My opinion ..its not going to be a good idea..Heat retention
I use electrical varnish in the block (inside) helps oil move freely and doesn't allow buildup of any kind, because electric motors run at such a hi temp, heat from the engine doesn't effect its adhesion properties, works good without plugging up any oil galleys like ceramic coating might do
Like he said. Some major engine makers coated the oil p***ages with it to 'seal' the pores in the cast iron and make oil drainback to the oil pan faster.
