My turn to do valve seals

This sounds plausible as the turbo N63 is going to run A LOT hotter on the exhaust side and the rubber on the seals may be a different / better material. I decided not to even go that route as I had no way of verifying they are in fact the same dimensions.

Both Elring Klinger and Victor Reinz are OE suppliers for BMW. When a seal is first introduced they are typically all from the same supplier, but that doesn't last long. Within a very short period of time, all the OE suppliers will be making the seal and the only people who are going to know what supplier they bought them from is the buying group. If they meet the specs BMW considers them interchangeable and uses the same part number. If anyone at a dealership tells you otherwise they are just guessing or passing on hearsay.

That's just my $.02 though, take it for what it's worth lol.

According to AGA's website, the Elring seals are the way to go. They are an improved design. I think you made the right call.

Which tool are you using for the install? AGA?
