Oil puddle on top of engine

Picture attached of a 2.7L engine without the intake manifold.

Orange color in picture is where the oil puddle is.
Blue circled part is the valve cover.

My plan was to simply replace the valve cover gasket and make a DIY write up for everyone.

But looking through numberous Porsche parts suppliers including Pelicanparts, I cannot find a valve cover gasket for sale. All I can find is a valve cover sealant.

So my question is. Did Porsche even install a valve gover gasket? Or did they use this sealant to seal the valve cover?
http://www.pelicanparts.com/More_Info/000-043-204-35-M258.htm?Loctite%20%35%39%30%30%20%28%35%30%20ml%2 0Tube%29%20%20%20

Does anyone think that the oil could possibly be seaping out of the intake manifold gasket? It is normal for some small amounts oil to get into the intake manifold gasket.

I may as well just replace the sparkplugs at the same time since I will be removing the side engine cover behind the rear wheels.

Those German engine mechanics could not hold a gasket aligned and in place while bolting the covers. it kept falling off, so being brilliant as they are they used a sealant gasket instead. {Joking ... cause honestly I dont know}

That oil on top must get hot and smell bad, I would also suspect the cover seal as you do, but isn't the AOS Oil seperator plumbing near that area as well? I would suspect that as well as I have read that sometimes the connections don't seal well and it could leak.

The oil cooler with it's 4 'O' rings are in that left rear area of the engine. I just changed my 13 year old 'O' rings on the cooler when I replaced all the radiator hose rubber. The old 'O' rings were fairly flattened but I didn't have a leak.

Wow, that engine looks big outside of it's cage.

Make sure it's not PS fluid. The res. sits left front on top of the engine.

jaykay wins, Pentosin CHF (ps fluid) is blue.

I mopped up a bunch of it from the same place, before adding an RSS pulley for maintaining high revs on track.
Problem solved after changing pulley and sphinning the ps pump more slowly.

i had a small oil puddle in the same area. it was due to my AOS spitting oil into used my intake manifold. the bad AOS caused an excessive vacuum which i beleive had sucked in and pinched one of my intake boots allowing some oil to drip out. with the air intake, throttle body, and resonator tunes removed, while i was cleaning up the oil with some paper towels i also found a screw in the oil puddle that had fallen out of the bottom of the resonator tubes butterfly valve. aos replacement, new boots amd hose clamps and reattaching the fallen screw seems to have fixed the oil dripping onto the engine. i dont know if it is what is causing your puddle but it may be worth checking aos and boots. best of luck to you

FYI; Many Boxsters were built in Poland. Blame it on the Poles. Not a racist, I'm of part Polish decent
