[W126 Coupe] Engine Ticking 89 560 SEC & Harder Starting

[Dick Spellman]

Hi jack:

Can you pull the spark plugs and have a look at them?  Might be you have 
one fouling out a bit from oil or fuel.  You don't mention when the 
injectors were done.  Could also be a tired hydraulic compensator that 
needs a moment or too for the typical engine oiling to quiet it down.  
What viscosity motor oil and type are you using?  Engine runs smooth at 
cold start and thereafter, right?

Regards,

Dick
