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
I just had a thought. I've read that a ball bearing can be used to block the EGR tube, and one guy used a small metal disc. Since I have no ball bearings around, believe it or not, would something else work? I'm thinking a tin foil cap or some aluminum tape?

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). On 11/10/05, Trampas [EMAIL PROTECTED] wrote: Put a BB in the vacuum line going to EGR.

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
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
