Does anyone have some black oily residue floating about the surface of their coolant when observed through the coolant filler port? It is not as though the entire surface is covered but is more like microscopic droplets of oil floating about. There is a similar smoky oily film residue appearing on the MAX filler indicator as well as all over the interior of the cap (I can clean it off the cap but it simply gets re-coated within a few miles of driving).

I hope this is some type of assembly lube floating its way to the top of the system rather than the indication of a head gasket leak or the like.

For what it is worth, my Cayman S has 9,650 miles on it and it has consumed 2 quarts of antifreeze to date.

Your personal observations would be appreciated!

Joe

Joe,

I'm certainly not a Cayman expert, having just taken delivery of my CS a couple of months ago but I can tell you that I have never seen any oily residue like you describe.

I would be very concerned if my car had consumed 2 quarts of coolant in it's first 10000 miles.

I would have your dealer take a look at this ASAP.

Good luck.

Bart

any coolant in your oilpan?

Take it to the dealer ASAP. Your Cayman should consume exactly NO coolant. You either have a leak somewhere, or you could have one or two blown head gaskets, or who knows what. Hopefully it's just a coolant leak somewhere. Two quarts is a big problem.

I would drain the oil and collect a sample to send to Blackstone Laboratories - Gas Engines

I would use a syringe and collect a coolant sample from the filler neck then ask them if they can analyze the coolant, if not I would find someone who can.

Contact the dealer to tell them my concern and express you think the car should be brought in for their inspection.

Wait to receive the results from the samples.

What you are describing sounds like a head gasket. I agree with others, see dealer ASAP !

I'm not sure I'd jump to any dire conclusions - a lot of things can look like an oil-ish substance - maybe caused by condensation, who knows... You shouldn't have had to put that much coolant in there in that short amount of time, imo... most likely you have a leak someplace and there's some sort of contamination in the fluid. If it was a blown or leaky head gasket you'd see coolant being burned out your tailpipe, and your performance would suffer enough that you'd know. That said, you should take it into the dealer and have them check it out.

There is also the possibility of putting the wrong fluids in the wrong filler. It has happened often enough to believe it can be an easy mistake to make.

For what its worth, one of my friends with an '06 S, at about 5K, noticed the loss of fluid in the same way...after several trips to the dealer the agreed that there was indeed a leak in the block. Porsche replaced the engine N/C. I am very impressed with that. Not too may companies would do that (of course maybe they know something??) So take it in right away...and let us know what they find.

A misaligned block seal caused the low coolant light in my CS to flash with all the regularity of a Robert Downey Jr house arrest. Porsche of Roanoke replaced the entire engine at roughly 800 miles, allowing me the opportunity to drive the Unholy Cayenne S of Impending High Speed Dismemberment around the mountains of Virginia for a couple of weeks. Granted, my Cayman was sucking down expensive Porsche coolant like a wino on a three day bender (I'm pretty sure that stuff costs more per liter than a good single malt), but I agree with everyone else: Any substantial use of coolant doesn't bode well. Especially if there's oil residue visible in the fill neck itself. I'd run it over to the dealer pronto and let them hook up the ol' pressure tester to it.

I'd say head gasket, which is not good. I've had that one myself on a Morgan Plus 8, very nasty.

Hello Veloyellow,

I appreciate your and everyone else's comments and suggestions. You said there was a leak in your friends CS block. Would you be able to find out a more specific location of the leak.

Thank you,
Joe

[quote=josephsdesimone;291204] Would you be able to find out a more specific location of the leak.

Hello Joe:
Unfortunately most of the times these leaks don't show on the 'outside' of the engine, therefore I am assuming that if you are getting oil on the coolant is through an 'internal' leak usually on the head gasket where the oil and water passages are close to each other. (I doubt that you have a craked head)

On the bright side your car still under warranty, can you imagine having an internal coolant leakage at 42,000 miles? I would take the car to the dealer
to report the coolant consuption

...Most of the coolant issues are the result of build quality issues at the factory, and show themselves quickly. At least, I'd hate to think it was an actual design and engineering issue.
