Ceramic Coatings

I was told by the company I hired to do a Ceramic Coating on my cylinder heads and valves it will not last.

That at best I MIGHT get 50K use.

So WTF I thought it would last the life of the engine.

Am I getting the wrong coating and there is one that lasts??

Or can I have them double coat the head and valve faces to double to life of the coatings??

I doubt double coating will double the duration the coating remains viable/effective ,
but it certainly should help, and 50K is not a bad length of life on any engine surface coating,
Id go for adding the thermal barrier coating personally IF the cost is not ridiculously expensive
 
theres always compromises made, if you feel $200 is worth the price for 50k miles of added thermal protection, then Id go for it, with the amount I drive my project cars thats probably 6-9 years. and by that time youll likely have rebuilt or significantly changed the engine combo
 
The idea is to get max performance out of the fuel and I plan on running lean burn as well.

I am not a engine builder per say. This is my third engine build in my life, the first was a Studebaker 289 around 16/17 1964/5, done by a friend doing a automotive tech school, then around 1972 I did a TR4's engine my self..both did not last...

From then until now I bought good low mileage junk yard engines to do swap and replacements.

IF this special engine could be bought I would have done that. But no one does any like it so I had to do it myself.

But your right, it has become a money pit... so in for an pinch in for a pound.

It is going into my stealth RV G20 Van, for road trips all over the country and as a road trip van may never see 50k...

But say 10 cross country trips in the next 10 years and I just might do it...so as the last part of a stupid build I might as well go for it...that way IF I do love getting on the road I would like to not worry that what has worked so well for say 40K is shortly doomed to begin failing away...

My plan is once built to drive it until one of us dies and I THINK I will be first....After all I just passed 75K myself.

keep in mind part of the issue is based on the fact that ceramic coating do not expand and contract at the same rate as the underlying metals thus eventually stress cracks and flakes micro structures on the ceramics
