The crank can simply be Magnafluxed, WPC’ed and reused with no problems. To be safe, we are going to replace the crank, as it has seen 3 years of Formula Drift abuse. Thanks to WPC, it has never had to be machined before!
The exhaust pitting is because the exhaust valve must open against a turbo motor’s increased pressure, which puts a lot more load on the exhaust side of the valvetrain. Thanks to WPC treatment, the exhaust lobes of the cam still had zero wear even with the pitted rollers!
Overall, I would say that WPC treatment is one of the main factors involved with more than doubling this engine’s service life. This makes it worth its weight in gold. WPC is a cheap investment- especially when compared to the cost of just about any other part of the engine!
We will continue to use WPC Treatment in any part that moves and has the potential of metal to metal contact or wearing against another metal part in the future. We can safely say that WPC saves money not only in parts consumption, but for less tangible issues like the cost of not finishing and the impact on a program that not finishing can have.
Due to its relatively low cost, we would use WPC to extend the life of and reduce friction in anything from street builds to as serious and as high stake Motorsports as it can get!

I would like to know more about WPC.
This is wonderful technology.
How Can I get benefit of WPC Technique and what will be your terms & Condition.
The link to WPC and articles explaining about WPC in detail are in this article.
