valve adj/ tune-up


Recommended Posts

Greetings! Pretty new 911 owner here. I have a 1989 C4 with no good service records (I know, I know). Anyway, it has 97K miles on it and I'm adjusting the valves and giving a tuneup. I have a few questions:

1. While removing one of the ignition leads on the bottom distributer cap the connection felt loose ond the wire. The connection inside the boot was broken. The wire looks good. The stab on the distributer cap was whitened while all the other stabs are good and shiny.

-I ordered a new ignition wire connector; do I need to attach it back on with a regular wire crimper or is there some special Porsche tool required?

2. All the distributer contacts and the distributer rotor contacts were blackened and pitted all to hell.

-Does this mean there is a timing problem or just distributer caps that are long overdue for replacement? i have new rotors and caps to replace.

-Does this mean I was not getting all the power I could out of the engine? Is there any reason to be concerned with all those cylinders not getting full spark?

the wire screws in to the connector, if it is broken you are not getting spark to that plug. the engine has a dual plug set up so the cylinder was getting fire.

while you have it apart make sure that the belt in the dist. isn't broken. if you can turn one rotor and not the other the belt is broken
