Re: [MBZ] horryfying discovery at EGR valve
Tested the car today after valve adjustment and after all, replacing the pressure line to the Alda. 14.86 seconds from 0 to 100km/h (Magellan GPS). I vote for the crap being left in the manifold.

Re: [MBZ] horryfying discovery at EGR valve
Nope. Gotta come off. Do NOT scrape away at it, you could dislodge a chunk that could get sucked into the cylinder and bend a rod or clog a prechamber. Use synthetic oil to help prevent the buildup -- neither of our 603s have any coked oil/soot mess at 150,000 plus miles. Peter

I don't like that fix. I remove the vacuum line and plug the lead toward the vacuum source with a golf tee (be sure IT doesn't leak - some cheap ones DO). As to the port where the EGR connects, it can be blocked with a plate IF the EGR won't close. If the EGR closes, there is NO need to block the port. If you feel better about blocking it anyway - do it...

Re: [MBZ] horryfying discovery at EGR valve
A BB will disable the valve but will not prevent exhaust recirculation if the valve does not perfectly seat. With the crud in there I saw, it will most likely not. A simple sheet metal plate inserted between the valve flange and the manifold will positively stop that crud. All one needs is a pair of tin snips, a soup can and the wrenches (4mm Allen and a 11mm socket).
