thats why I run a Wicked Diesel pump... have you ever heard of a parts issue like this? I havent
I have heard the same happening to WD pumps, just not as quickly. It is because of the side load exerted on the cylinder walls because of the stroked cam. the walls of the modded pumps are not coated after they are bored, that is what Exergy is testing right now. I can't say that is exactly what has happened to mine, but it has been reported by many to be the problem in all big modified cp3's to date.
