Quick question - has anyone had any parts (like exhaust manifolds) coated in thermal ceramic coating? I'm going to have to do a few different gaskets on my car soon...its the final item after renewing everything from shattered axles to a melting injector harness and I was thinking I might aswell get everything coated and painted like some of the nicer engines you see here, I was thinking everything from filter box to valve covers in a suitable colour scheme with high temp ceramic coating.

Are there any downsides to this? Expansion of parts vs uncoated?

 

exhaust manifolds , done in 1994, still great.

 

Cost, here in Australia anyway it's going cost me $1000 to have my exhaust manifolds coated.

I would not bother with cam covers and intake manifolds but exhaust manifolds are worth doing.

 

Thats insane, I was quoted about $200 for the manifolds. At $1000 you'd be better off buying the equipment yourself and have a side business lol.

 

That's just Australia, we have become one of the most expensive countries in the world.

 

Very interesting technique.


1. In the late 40's my school pal, Roy majored in physics. Brilliant guy. Went on to become a "rocket scientist". But, as a 'relaxant", signed up for Ceramics. Far from the expected "pottery class". High tech coatings for high temp and high wear applications ! More likely than not, useful in his rocketry.


2. Some Early GM and probably other makers used Ceramics on exhaust manifolds.


3. Tongue in cheek. Nannyism ain't cheap.

carl i remember those old porcelain coated exhaust manifolds , mostly on expensive cars!

it looked good , until you oveheated the coating (long hyway runs) and expansion chipped it off in small places ,then rust set in and looks went to hell.

not much thermal barrier either.

the new stuff seems to be much improved .

it was a NASA development for afterburners on jet engines!
