Ceramic Coating an Engine Block?

[sswee]

The older engines run from 165 to 195 degrees. Most of the newer engines are designed to run 210 degrees. for a better burn. I have used acrylic enamels and polyurethanes on many motors with no problems. PC is better yet. Only on exhaust manifolds or headers do you need the high temp. coatings. As for the ceramic coating, I have only seen headers with this coating. Any coating that hinders heat dissipation too much is going to cause problems. Have you ever leaned on a car after it has sat in the sun all day?

Thanks Sswee:
I know the engine running temp is roughly 195F. But I thought the heat transfer temp (external) was much higher? Have you had ggod long term results using regular PC? Any idea what a motorcycle engine runs at?
Thanks Again

Can't say off the top of my head what temp. MC motors run. I would have to check but it can't be that much different even considering it being air cooled. Too much temp causes oil break down and detontion just to list a few. I have a 78 KZ1000 Police and a 82 Harley XLS. I can tell you the majority of colors on Harley motors is PC. The PC I have, I had done and it holds up better than any paint. I am just trying to get set up for PC now. Catalyzed polyurathane used to run a tight race with PC but since paint manufacturers pulled the lead out it don't seem as durable to me anymore.

Ive PC'ed at least 2 dozen engines and the oldest 1 is about 3 years old and still looks like new...
Getting ready to PC a 289 out of my 68 mustang.
