W126 manifold gasket help needed

[gunning]

Evening all,

My 126 has blown a manifold gasket drivers side second from the front (I bought it knowing this). Looks a tight job, has anyone done this? Does anybody have any tips?

It looks like the manifold is in two separate pieces but unsure if that helps or hinders me.

Any info would greatly be appropriated!

Remove the entire intake and replace both gaskets.

sorry, I probably should of been clearer. Exhaust manifold not intake

You're probably going to have to disconnect the exhaust downpipes to remove the manifold and possibly raise the engine on side. It's been a while so I can't remember, and the 560's on this side of the pond had exhausts that were routed differently. Is is it a log style manifold or 2 or 3pc setup?

You will be able to get to all the nuts with a socket or a spanner. I'd first try to tighten them as you might find that the nuts had backed themselves out, and simply tightening them will resolve the leak. I've had a few 560's that did that.
