Approaching 100k miles, leaks were found at the plug, the valve cover
gasket, and the oil filler tube. The cam end plug seals the opening
in the valve cover which is used to attach the distributor on the non-turbo
models. It is a common source of oil leaks, just like the distributor
shaft on the 900S model. The plug is separate from the valve cover
gasket, but if it is leaking, it is best to replace or reseal it at the
same time as the valve cover gaskets, because the valve cover has to come
off for both jobs. |

The plug can be either replaced, or sealed with
high-temp silicone sealer. Following advice on the Saabnet board,
the plug was sealed rather than installing a new one.
a) Original leak (leaking for 6-8 months, perhaps more)
b) Few weeks after quick cleaning, ugly but minimal seepage
c) After plug reinstalled with hi-temp sealer
d) EPC diagram detail
e) Plug clamp and torx screws with valve cover removed |

There are two different plugs, depending on the
model year. Saab EPC and the Haynes manual both show the earlier
version. EPC lists both part numbers.
Large plug and o-ring: p/n 9169285, 7519143, ('94-95)
Plug shown in the pics: p/n 9135211, ('96-98)
Torx screw: 7504178 (requires a hollow point torx bit)
