Ignition wire gasket

[RevMatcher]

2002 911 C2 Coupe

I'm having the classic misfire on cylinder 1 when the car is wet.  I used contact cleaner on the ignition wire plug into the coil and it works fine for now.  I/m sure when it gets rained on it will misfire again.  Already replaced spark plugs.  I discovered there is a tear in the little orange gasket (green arrow in photo) on the ignition wire connector and water is getting in there when it rains.  Anybody know where I can find a replacement without buying a new $812 engine wiring harness?

Thanks

PS wish my engine was that clean.

Take a look at this part number.  It is a $3.41 new connector.  http://www.autoatlanta.com/tinyresults.php?pn=99965291640;TB_iframe=true&height=550&width=875

You can probably either figure out how the pins come out, or just pry off the gasket and install the new one.

Thanks Joe!  The gasket just slides off anyway, should be an easy fix.  Except for jacking up the car, getting it on stands, pulling the wheel, removing the cover, and working my hands up between the header and engine to remove the connector, then one-handing the dust boot off of course.

Misfire Cylinder 1.  Took it apart for the fourth time.  Finally realized THIS (see photos).  There is a crack in the side of the coil pack.  I have seen photos of coil packs with far worse cracking, even blistering.  The issue is that I drive in the rain all the time, and sometimes the car is left at the airport for a few days.  Every time I come back after rain, I get the misfire.  A few dry days, it goes away.  So, I cleaned out the cracks with electronic contact cleaner, which is like ether and evaporates very quickly.  Then I filled the cracks with hi-temp automotive silicone.  It's an experiment.  I will replace the coil if it fails again.

It will.  I'd suggest ordering a replacement.

I have posted this before... the resistance is the best way to check your coils.

I always check them whenever I them off for spark plug changes as well as when I see P0300 codes.

 

For the 996 series cars (and 997-1 series)

Resistance between terminal 1 and terminal 15 at 20°C: 0.3 - 0.7 Ohms

Replace them all.
