83 240D Leaky Oil Pressure Gauge
 

....after 4 or 5 days of repeatedly noticing Oil on my shoes, I suddenly realized what was going on. I replaced the oil Pressure sensing line when I was changing engines. I did tighten it securely.
I snapped the old line when I forgot to disconnect it when I was hoisting the old engine out, and I probably stressed the Oil Pressure Guage.

Tonite, I will pull the console box. Is the Oil Pressure Guage repairable or do I have to repace it?

Though I cannot answer conclusively I thought that I had read somewhere here that the answer is replace...
Sorry for the bad news.

Could it just be though that the connection is not as it should be? I'm trying to think positive for you...:)
