That said, while you have the entire front assembly apart you may want to go ahead and clean your vanos solenoids and replace the o-rings, will be two large o-rings and two small o-rings, pretty cheap and very easy while you're in there. For $25 bucks +\-, you may want to grab a vacuum pump rebuild kit as well and possibly, proactively replace the vacuum tube running from the pump to the brake booster. If that one way valve fails it will (can) suck oil into the brake booster and then you're up dooh dooh creek...

Thanks. Just added a few more items including the expansion tank, level sensor as well as the t-stat for the trans cooler. I'm planning to go the AGA pipe route so I don't have to take the front end apart but have thought about replacing any o-rings up front to be proactive, as you say. I just replaced the vacuum tube to the brake booster this past summer...because it was clicking. But may as well rebuild the vacuum pump, too. Do you have a kit you would recommend?
It already appears as though my vanos solenoid valve o-ring is leaking. So I'll plan on that as well.
