i recently have not been hearing my factory diverter valves woosh, or its been silent. which blow off valve, or diverter valve will not set a DTC and give me some sound. is forge a decent one to check out?
I've got some Mobil 1 or Valvoline hi-temp synthetic bearing grease. Usually new o-rings every 2-3 years as well.What do you use when you regrease? My 007 is way overdue.
To OP, go with the forge. Never have to buy another one, only requires periodic maintenance (that I'm obviously ignoring).
