993 Secondary air induction supply = top end rebuild
My check engine light came on and I have been informed that my secondary air induction supply needs to be replaced (basically a top end rebuild) from carbon build up. A 993 factory problem-
Has anyone had any experience with this? |

Known issue. Check out a DIY procedure at p-car.com
Don't know if mine is affected (probably all 993's are) but a '95 has OBD1 and does not throw the CEL (check engine light). http://p-car.com/diy/sai/1/sai.htm Clive.

A constant topic of discussion over on the Rennlist 993 board.
there are several different failure modes
most can be alleviated w/o a top end rebuild, but in the worst case scenario, worn valve guides contribute to the blocked ports in the exhaust, this leads to a full to end rebuild

This is a HOT topic. Do a search for CEL, carbon, obdII etc. and you will get hits that discuss this in depth. Also a topic over at Rennlist and even in Excellence magazine!!
Hot Hot Hot!  Do NOT get a top end re-build until you read these posts and get informed. It could save you big $$$! Just me thoughts...
