Wow, you sound that convinced. Guess I'll have to go clean a pair of VANOS. Thanks. I'd have done it long ago if I'd realized how simple it would be (I think).
Agree that counterfeit parts are a huge problem. I bought some front suspension parts several years back, supposedly MOOG brand. The metal was die stamped MOOG, but it looked like a very generic font and I was suspicious. I actually contacted MOOG directly. Their person's response? "If it says MOOG on it then it's probably real." Whuhhht?
