I am trying to find my exhaust leak and a friend suggested where the secondary air injection pipe is connected to the headers can break and leak. But I can't find a secondary injection system in my 997.2 looking at my PET Katalog diagrams.

Thanx..... the PET Katalog makes reference to secondary air injection... relay location etc... but no pump. These diagrams and parts diagrams have a bunch of errors in them.

Interesting. I wonder if they still call the whole process of increased air through the exhaust "secondary air injection" even though it's achieved differently. Could those relays be associated with the cold start procedure it goes through?? I'm just guessing here and have no idea.

Only a guess: the documentation is full of errors. I found many over the years including drawings that don't resemble the real part... etc. I think with each model, they update the old... and there are ton of leftovers.Originally Posted by mikemessi
