w126 Crossover pipe gasket...

is just beginning to leak but getting worse every week. Is there a gasket also on the EGR side? Is the R&R as easy as it looks, a few bolts?

There is a gasket on the manifold side but an O-ring, IIRC, on the EGR side. The O-ring can typically be used again. The R&R is as easy as it looks. Two socket head cap screws and it's out.

I usually leave one socket head cap screw in place at the turbo side of the crossover pipe, leave the angle bracket attached to the pipe. I use the flat gaskeet over again. A paper gasket could suffice for the manifold side, I know I've lost one down the side of the IP when removing the pipe you have to be there to grab it as it falls straight down (hint).

The oring on the egr side seems to be made out of viton or someting similer, (its green). Usually you can reuse it even if its original, however it wouldn't hurt to change it.

Their are three bolts, two attaching the cross over to the manifold, and the third over by the egr.

Both gaskets are cheap. The rectangular one will probably stick partially on one of the sealing surfaces and break when you pull the pipe.

A BIG thanks...

to everyone, best to get a confirmation first. I am surprised by the leak as a head gasket repair was done only 10K miles ago. They must have reused the original gasket... THANKS!

While working on the gasket, examine the plastic clips that hold the IP lines together under the intake manifold, as well as those that clamp the lines to brackets. I recently saw a serious fuel leak from worn lines. A new set BTW runs almost $200. Here's a case where ten bucks in time saves $200.

have been either replaced or secured with plastic ties so that is something I shouldn't need to do.

Does anyone know if the crossover has a metal gasket? I ordered it today and the dealer thought it was metal. Sound correct?

No the EGR gasket is metal. The crossover is black and rubber/paperish.
