How much crap can I yank off the valve cover? - PeachParts Mercedes-Benz Forum

Hi guys,

It looks like when I remove my Timing chain tensioner to replace the gasket, I'll change the timing chain as well........ Which means pulling the valve cover. Right now my EGR is in place, but has a thin steel plate that somehow snuck in between the EGR valve and the Intake manifold.........

But, I still have the 3-2 valves and their lines intact, (Old egr hookup port is plugged....) I've been reading on removing the vac lines and stuff for this unit, but I want to know, how much of this mechanical crap can I remove from the valve cover....... I want more of it showing for when I get around to polishing it!

I'm not against cutting some of the stuff apart with a saw if that's what it'll take...................... I'm ready to get serious with the stuff!

It is according to which car it is. If it is a w123 240D you need to keep the valve that controls the signal to the tranny. If the car has a bowden cable then you can eliminate most of it.

You do have an extra hand and the crimper for the chain right?

Yah, the extra hands are called a Dad......

I've also sourced the chain press too......

Have you thought about resetting your cam timing instead of replacing the chain? You'll only have to spend about $10 remove all of the stretch instead the cost of a new chain.

Yah, well, I'm worried about chain breakage. Since I have no idea how the PO did maintenance like oil changes etc, I figure just replace her...... Already got the chain and stuff anywho............

Anyway, back to my original question. Yah, I know I can remove the black box, but anything else? probably not if I want to keep the cruise linkage intact.

I removed the box, and all the stuff attached to it. You can kinda see it in this pic I posted of my stop lever.

"Resetting" the valve timing and removing chain stretch are two different concepts.

Yes, but you don't need a new chain simply because your old one is stretched. By installing the proper offset key, your cam timing will be the same as when you install the new chain. My understanding of the FSM is that a new chain is necessary only when the stretch is no longer correctable via an offset key.
