Hi,
This week I have noticed a new sound from my '87 300d.
It appears to be associated with the throttle in that when I accelerate the noise increases and the opposite occurs when I slow down.
I have also noticed an increase in the odor of diesel at startup. Listening under the hood, the noise seems to be coming from the passenger side of the engine towards the front. But I am having a hard time pinpointing exactly where it originates from.
I've got 240,000 miles on it and is my daily driver. It still starts up in sub zero weather and I have not noticed any other ill effects other then the noise and smell along with a reduction in MPG.
I checked the fluid level of the transmission and it looks ok, I mention this because I was thinking that the noise may be reflecting off the noise reduction panel on the underside of the engine bay and may actually be coming from further back.
I would surely appreciate the opinion of this membership. I am worried that I may be listening to the impending failure of one of the systems. Could I be looking at a problem with the IP or something else in the fuel delivery system?
Thanks much.........
Glen
