So I did some work on my Boxster this weekend and noticed some coolant traces on the bottom of the 3.4L engine. The leak is very slow and I haven't noticed any coolant on my garage floor yet.
Tracing the coolant up to it's highest point I found some on a flat spot just above the oil pump. It's possible the leak is coming from the "water housing cover" (99610621701) which I installed with a new gasket during the conversion process. It's hard to tell exactly because there is no coolant traces leading directly to the cover. Are there any other possible sources for this leak around this part of the engine?
