[W126 Coupe] Valve tap/ticking

[kenhartz at comcast.net]

I have an 86 560 SEC with 330,000 miles on it.  The top end was done at around 250,000, and ran pretty good up untill recently.  I have developped a tapping/ticking noise on the right hand (passenger side) valve bank.  It seems to be coming from one of the middle lifters/rockers.  I initially thought it might be a st icking hydraulic lifter, so I added seafoam, to the oil, and ran it for about 100 miles, and changed the oil. That didn't seem to make the problem worse, or better.   The noise is worse when the motor is hot, and it is pretty bad.  I am trying to nurse the car along for a little while longer, till I can retire it as an everyday driver.  I have my sights on getting a 2003-2005 CL55.  Anyway, if anyone can shed some light as to the possible problem, and cure, that would be appreciated. 



Thanks 

Ken
