Engine Coatings
Long story short, a few ordered part glitches are preventing delivery of my baby. In the meantime, I'm thinking of having a few parts ceramic coated:
Oil Shedding:
- connecting rods
- crankshaft
Lubricating coating:
- bearings (for sure)
- valve stems
Anyone have any experience with this? Is the expense worth it (outside of the bearings)? Or is it just throwing money at very minimal gain (less than 1% gain)? It'd be about $600 bones for all of the above.
I've read up on it a bit (potentially biased content) but am interested in getting additional feedback/discussion going. TIA!

You might as well talk to yourself since TopRamen seems to be away
Personally I wouldn't waste the $$ since you are not producing humongous power.

Re: Engine Coatings (ak)
I know, I know. But somebody outside of nick has to introduce new content. 
I'm thinking just the pistons (domes and skirts) and the bearings. There's some hp to be gained in the oil shedding coatings but perhaps not enough to offset the lubricity and cooling properties of the oil.

Re: Engine Coatings (Ponyboy)
From my experience and from seeing engines over the years i can say that most professional race team use coatings(ceramic or other exotic coatings) The oil shedding is a definate plus as well as the extra protection. It is definately not a black and white mod but might be worth looking into to. Then again $600 can be used elsewhere

Actually thermal barrier coatings on the piston tops, and anti-friction coatings on the piston skirts are all you need unless you are building a racing engine. Oil- shedding coating inside the valve covers and the oil pan are probably overkill at your build level. Coating the bottom end bearings was not recommended by my engine builder.

Yeah, most do. But again they have the option of rebuilding their engine as much as they can afford. The negative, as I've come to read, in the oil shedding coatings is that the oil is used as a key way to extract heat in the recepricating parts and I'm not sure I want to dilute the oil's effectiveness in that area.

Did your engine builder give a specific reason why?

Sorry about the delayed response; I'll call him tomorrow and ask him.

Probably because you want bearings to retain oil, not shed oil.

Indeed, you do. That's why we were talking about dry film solid lubricating coatings on the bearings.
