My valve is already leaking oil. When I removed the vacuum hose to check with my MV I saw oil into the hose and at the vacuum valve. The MV read almost zero vacuum when pumping it. I need to have it replaced ASAP and as I said in previous post I have one IP from a sold 240D which according to Shertex,240 D use the same part used on 300 SD.
mThe lowest price found for a new valve is $ 88.70 at Amazon.com. Other online stores sale it for $174.00 and above. Thanks for your reply.
