No, no valve train noise -- nearly perfect car. Synthetic may and may not fix a sticky lifter, would depend on why it is stuck.

If it is crudded up, it might, but if it is leaking or scored, no change.

I am assuming you are talking about the 87 300SDL -- if you have valve noise in an older engine, it needs valve adjustment or repair as they do not not have hydraulic valve adjusters.
