@@fredzimmer8626 I cannot argue with you on the B8.5 S4 being a timeless perfect example. I believe it’s going to turn into a collectors car similar to the B5 S4.

This is aspirational for my B9 SQ5 that I love even stock. No one is tuning them like this in the UK. I can't find the answer anywhere but do you know what the standard engine internals are rated to in terms of power? And the ZF in terms of torque?

[@Need4Built]

I hope to see you build yours! The B9 3.0t rods are rated for 600wtq at a safe limit. I’m making 620wtq/640whp without any issues for 10k miles already. The zf8 transmission, 8hp55 is is rated for upwards of 800wtq I believe. It’s insane. The trans is more bullet proof than the engine. We have seen a few people make 700whp/700wtq without issues but that’s kind of a huge danger zone. The power I’m at right now is right there at the safe limit.

I'm now confused as to which of the three parts fail. 034 seems to only specify the host part you've replaced as being the issue (with its check value). You show the PCV itself being replaced for its gasket (this fails as a result of the check valve failing right? As only then does the pressure burst it). The other hose that goes under the turbo is also a PCV hose, but is this involved in any of the failures? I assume not as you didn't replace it
