DIY - B6 1.8t - Vacuum line and Check Valve removal/simplification

[Charles.waite]

Pulled the intake manifold off and was in awe at the rats nest of vacuum lines I found under it.

I'mma let you finish but if you want to see a REAL rats nest, feast your eyes on the 1970s Toyota 2F engine:

That wasn't even the CARB compliant version which is somehow even worse. The 1.8t really isn't bad, there aren't superfulous or unnecessary lines. If you hate that stuff thats your prerogative, but be aware shit doesn't work as well with that stuff removed...

It started right up and runs just fine. I'm not really sure what won't work as well. I like these A4s because the motor's not in there sideways and I can get to things to work on them without working against the firewall too much. Same concept as a Cummins. Much easier to do anything on that motor as a opposed to a V8. Apples to oranges, but it makes sense in my mind. That rat's nest was hindering the simplicity of it all to me. It's all gone, the cat too. Quite a bit more room in the bay now. I can appreciate that some guys like to keep it or need to for emissions reasons. I'm just not one of those people. I bet you can also delete all that garbage on that Toyota engine and I wouldn't be surprised if it is common practice. I could be wrong though.
