I searched and read previous posts regarding disabling the EGR valve on the diesels. Most of the discussion was on the 123s. The general consensus said it was okay to block the passage way between the valve and the intake.

Does anyone know specifically, if I do this on my 1987 300D Turbo, will I suffer any repercussions? Will affect any electronics and/or will I have to modify anything else? I plan to cut a metal plate to insert between the EGR valve and where it bolts to the intake.

When we replaced the injectors two months ago, we cleaned the intake from the EGR valve. This weekend as I replaced the injection pump diaphram (it's nice to stop the car without lifting the hood!), I noticed all the oil and goop that had started refilling the intake passageway just beyond the EGR valve. Since this engine has 292,000 miles, I don't think I need all the blow-by recirculating again.

Any comments are always greatly appreciated!
