I need help!
 

I have a 1983 911sc cab.
I want to replace the aux. air valve, but it is at the back of the engine and is very hard to access the valve and hoses.

how do u guys replace it?

thank you!!

Anyone!

You can do a partial engine drop. You should do a search using the "search" button at the top right of the page. Type in "partial engine drop".
Not trying to be a wisea$$ but there are some good instructions on how to do this. It's not hard to do.

is it possible to replace it without a engine drop?

You'll spend more time and effort dismantling the entire top part of the motor. Lowering the motor slightly is the best way to get back there. Do you have room to work on the car (since one location you list is NYC)?

& Don't call it 'Frisco'
