okay, I have been putting this off for a while but today we reached the breaking point as we needed to purchase more brand-new valve covers from Mercedes in order to Teflon coat them. Over the years the valve covers we have been receiving back have been slowly degrading in quality due to their age. The main issue we are seeing with them is pitting of the magnesium aluminum alloy around the lower bolt holes. When they are still on your car this pitting is disguised by the dirt on them and does not become apparent until we get them fully cleaned off. Once we coat these valve covers the pitting subsides but I cannot justify sending someone a set of beautiful covers with pitting in them. As of right now I probably have six full sets of valve covers that will end up being scrapped due to their condition that I essentially paid $350 a set for.

I am sorry that it had to come to this, as it is surely more affordable for you to exchange your covers then need to buy new ones. We do not see this pitting in the intake manifolds or lower Y pipe, just the valve covers. We will continue the core exchange is on intake manifolds and lower Y pipes.

For those of you that have recently purchased valve covers from us, you have 30 days from the day the coated valve covers arrived to you to get your cores back here for the core refund assuming they are in good usable condition. There is no worry there, we will still honor the original core exchange agreement for those that are grandfathered in. But from here on out we no longer want old valve covers back.I hope everyone understands that this is required to ensure the quality of parts that you pull out of our box.

Thanks, Rob
