EGR Valve Repair or Replace
I need to repair or replace the EGR valve on my 88 560. The vacuum actuator part seems fine. It holds a vacuum and I can hear the valve shut when I release the vacuum.
When I did a smoke test, smoke came out of the area in the red circle.
A couple of questions:
1. In order to repair or replace, I need to remove it from the car. Unfortunately I can't get it free of the EGR tube. I can turn it on the tube and move it in and out a few millimeters, but it won't come off. I don't want to use too much force because the tube would be difficult to replace. Any ideas how to get it off? I've tried icing the tube and heating the body of the valve, but that didn't help. It seems the end of the tube is flared a bit.
2. Has anybody repaired one of these and is it possible? A replacement is $200.
