I'll call BS on your BS, I drove the car all winter (well from December until early May, about 5,000 miles total) with the cap loose at temps from the teens through the 70s. I also recall doing it with my '83 240D (although I don't remember why) during a whole summer. I think that one might have had a weeping radiator.
I'd say you already had a bad head gasket. At any rate it would be nice if somebody else with a non-suspect car could make a test. From cold loosen the radiator cap, run the car for about 15 minutes. It helps if the first 5 are moving. See if the car overheats. Mine does, every time. During that time the coolant is bubbling out of the radiator, think "witches cauldron". -Curt Date: Sun, 16 Jun 2013 02:46:15 -0500 From: Rick Knoble <rickkno...@hotmail.com> To: Mercedes Discussion List <mercedes@okiebenz.com> Subject: Re: [MBZ] I think its the end Message-ID: <bay404-eas3320c55b7804c3c8da53418dd...@phx.gbl> Content-Type: text/plain; charset="us-ascii" On Jun 15, 2013, at 11:32 PM, "Fmiser" <fmi...@gmail.com> wrote: > Curt's problem is that it's getting too hot.

That will relieve the pressure in the system and the coolant won't leak out as fast". I thought wrong. I was merrily motoring down the expressway when I thought to look down at the temp gauge. It was pegged. I blew the head gasket. Try it sometime. The pressure cap is a pressure cap for a reason.
