Ok, I've searched, and have not gotten sucha good answer. The SAI (secondary air injector - for new folks) has died. It actually took a LONG time from when it first started having issues. Quiet - airplane - gargling gravel - quiet again. :-) I too it out today to grab the PN since there are two different ones. And when I removed the first air tube, I drapped a solid cup or nearly 2 cups of water out of there. The other side had a little in and when I got it out (w/o removing the front bumer too!) and shook it, there was stilla LOT of water in there. Stupid thing. Luckily, it is the cheaper one. $270 at ECS Tuning versus the $350. "Lucky" me, but that is not the point of the post and is just background info.

This leads to the theory of the combination valve having a problem and allowing condensation (and alot of it) back in. Since is is the 30V V6, there are two (of course there are...). When attempting to blow into the outlet from the pump (the way the pump would) with the car off results in not an absolutely complete plug (but pretty much complete), but I was kinda wierd blowing into it. When I applied 8" vacuum, the combi valves opened up and I no longer had a plug. LEss than 8" would keep them closed. I tested each individually, as well as a pair by applying vacuum at teh "T" going to both. At $150 each, I don't want to have to donate any more than I need to for parts. This would seem to me that they are OK.

But if they are OK, how does one get water there? Granted it is a bit of water, but it has been a month or two since the SAI stopped working. I'm going through and trying to get this car back on top - she has a few issues. I'll order the SIA tomorrow, but what are your thoughts on the combi valves?
