Noisy SL500
 

Do you remember clipping cards to you bicycle spokes for the sound, when you were a kid? Well, the sound my 1998 Sl500 makes sounds just like that.
When I cut the engine off, there is a faint scent of gasoline.

I would appreciate any info on what I may be dealing with..
Thanks in advance..

Where is the noise coming from? Did you check the undercarriage, you may have something loose.

If you can't find it, Donnie is just around the corner. I am sure he will fix you right up. Wish I am that close so I can take my car in for him to look it over every now and then :D

If it is coming from the engine and you have the old 4 cam 32v
M119 V-8, there is a pretty good possibility one of the valve tappet oil delivery-tubes has lost it's end plug.
The oil to one lifter is lost, oil pressure drops and the lifter starts
"tappin" . removing the valve cover and inspecting all the little
brown plastic tubes between the cams is a good place to start.
if one is missing the little plug at the bottom, that is your culprit.
If one has failed, replace them all. pn# 119 180 03 66.

AGAIN, THIS ONLY APPLIES TO THE OLD M119 32V V-8.
and is a mere suggestion of a known problem.
