1994 S600 V12 Replacing my plastic oilers for my lifters
 

My mechanic told me that my lifters were ticking because a few of my plastic oilers were bad and no oil was getting to the lifters. At about 2000 rpm the ticking sound goes away, he said this was because the oil pressure built up enough to oil or lubricate the lifters. Is this something I can do myself. I do A LOT of my own work on all of my cars.
Thanks,
Christopher

This is common on the V8 M119, but I do not know it the M120 has any plastic guides;

Have a look here to see images of a rebuild M120 and see
if you can find plastic oilers there (I did not);

The M120 heads are M104 and mirrored M104 heads, so finding it on
a M104 would also answer your question (I think).

Or you could ask this man;-) ; (taken from http://mbwde.curry.hl-users.com/Mediengalerie/index.htm )

Thnaks for the reply. Is your information still ok, beiong that i have a w140 chas.? Any additave that i can put in oil to shut them up :)

:dizzy2:

Have a good mechanic that does a lot of work on these cars fix it.

Lifter noise(s) in M120 engines are rare except for cars with VERY high mileage OR where the oil change frequency is too Looooog.

No cam oiler tubes like the M119 engines

Not unless you want to do irreparable damage to the engine. Noise means something's wrong, and on a $130k car, you don't try to stop the noise with a $10 additive.
