Well, I did my purge last night and I have never seen better results from a purge.

I have had three or four W123 300D's and the diesel purge never made that much of a difference.

I've personally driven this car(W124) 27K miles and this is the first purge I've done on her.

In my W124, I am smoking much, much less after a cold startup. In fact, it is very minimal and I only saw that because I shined a flash light on the exhaust to see if it was smoking. It was dark outside.

I ran two cans through it and much of the time I was at or above 2000 rpm.

For about a minute, I was even over 3000rpm.

Should I have done this?

It seemed to have worked wonders but I was a little nervous while doing it.

I just wanted to get it as clean as possible.

With the purge, new tensioner shock, and two new engine mounts I can't believe how smooth it runs.

Before it would shudder at shut off and start up.

It also seems to smoke much less, if any at all, when I romp on it.

Before it would smoke quite a bit based on what I saw in the headlights behind me.

I couldn't see it from above but my driver side mount was completely collapsed.

The passenger side looked fine after I removed it.

I've never seen a mount collapsed like this one was.

Also, the replacement mounts have what looks like a BB on the bottom mounting surface.

Why is that there and what does it do?

The mounts I took off didn't have that ball/BB on them.

I know that these are supposed to be hydraulic mounts but I still don't get the ball valve looking thing on the mounting surface.
