Oil leakage - 993 - Urgent
My 1996 - 993 is leaking oil from the engine. After cleaning and running the engine warm oil is seeping through the left hand stainless steel exhaust manifold. The manifold has two hollow tubes running through it. In between the seems oil is leaking. Also the manifold seems to be folded together, not welded. IN between the folds the oil seems to come from inside the manifold.
Also have I noticed on the bottom of the airvents underneath the engine, connected to orange hard plastic hoses, also some oil drops. However the inside appears to be completely dry. Same for the exhaust pipes, there is no sign of oil, no fumes and the engine runs regular and well tuned. Any advice. MArcel |

I am pretty sure the hollow tubes you are referring to are the holes designed to allow an allen wrench through the heat exchangers to the allen bolts holding them onto the heads. It seems then that the oil is dropping down onto the heat exchangers and then pouring down through these holes. I guess that's not much help.
Good Luck,

Common oil leaks in the 993 involve lower cam cover gasket. More than likely the culprit and a fairly easy DIY.

lower valve cover gaskets most likely. they get real hard from the heat. (they're rubber). i replace a ton of them.
