[W126 Coupe] Re: (W126) Odd Trans Problem

Hi Demetre:

I'd pull the cylinder head covers and check the condition of your cam 
oiler tubes (visibly dislodged, cracked, broken).  Check each of the 
cams for galling or scoring.  Hard to see the rocker arm conditions 
without removal so don't bother.   Listen briefly (you'll be pushing oil 
over the sides of the cylinder head after a time so briefly means 
briefly) for and identify the cylinder with the ticking noise.  It could 
just be the hydraulic compensator.  Another quick check where you are 
blowing smoke is a compression test followed by a leak down test to see 
if you have a valve seal/guide or lower end problems.  What viscosity 
grade oil are you running?  What's the oil change interval?  What's the 
mileage on the engine?

Regards,

Dick
