[Shotimes] Cam Sensor Oil Leak / Replacement

[Steve Weinrich]

Chris,

There is a camshaft seal befind the sensor and the sensor mounting body.
The same seal is also used on both intake camshafts behind the sprockts for
the timing belt.

The Ford seals are fine, you can also buy a 3-piece set of seals for around
$15 aftermarket.

When the seal behind the cam sensor fails, oil drips out of the sensor body
and drips onto the rear cat/exhaust, causing a wonderful smokescreen.

Here is a cut and paste from an email I sent out to the list last fall
regarding this and my experience with it.
