Inside Oil Leak
I have a 1984 Mercedes 300D. Recently, I noticed a significant amount of oil on the floor near the gas pedal. I removed the plastic cover underneath the dash and found that some of the insulation was soaked in oil. It looks to be coming from behind the display, either the tach or the oil pressure. What might cause this and what would be the easiest way to fix it without ripping all the guts out from underneath the dash?
