I just bought a MKIV TT and noticed some oil in the HKS BOV and I'm assuming it's from the stock twins. There is some slight residue in the lower IC piping, but nothing crazy. The car has 67k miles and I was curious if the stock twins could be on there way out already. I tried a few different search's and no answers. So basically what is the average life of the stock twins you guys are seeing? Thanks- Newbie

A little bit of oil in the IC pipes is normal. The life of the twins usually depends on how hard they are boosted. I believe there is someone on the forum with original stock twins and has a ton of miles on them already. You'll know where they're about to go also due to the "death whine". You can go to www.mkiv.com to hear what it sounds like.

With BPU after about 70K you are on borrowed time. Which HKS BOV do you have and why? I'd think about removing it, the HKS SSBOV will cause compressor surge on a BPU car, that cha cha cha sound is not good.
