sunset porsche has great prices, but I do not know about their shipping cost to Canada. If you have oil in the J tube and the superior portion of the separator, you should check your throttle. Mine was puddled with oil; caused major idle problems, exhaust smoke, and it sucked. Here go to this link. i posted some pics. Oh and as far as replacing the J tube; I honestly don't see why this needs to be done. If you were to clean it really well, then you should be fine; however, I went ahead and replaced it.

BTW: I didn't change the spring clamp with a screw clamp. I was very careful and I confirmed a good seal. If I could go back however, I would have used a screw clamp.
