Granted I have not looked for long but I've yet to find a report of a failed Elring gasket, just lots of threads arguing about whether people should buy OE or not. I can return the head gasket set but I have to pay return shipping and a restocking fee to then pay twice as much for what's likely the exact same thing.

I use aftermarket, typically Elring or CRP seals.

VR left a bad taste in my mouth after doing a top end on an M103...sprung a leak from the oil pressure port in short order. This is common on this motor, but very with the VR gaskets. For instance, the 247k original gasket on the 300E weeps from the oil port some, the 50k VR gasket on the 300SEL pours out.

Their valve cover gaskets also crack apart fairly quick. I priced out an OEM M103 gasket at my dealer, it was about $51 picked up. Online is about $40 + freight.

The small set of orings and such, one is for the water pump and one is the rear cylinder head seal.
