Hey everyone,

A few weeks ago I repaired the oil level sender seal on my 89 420SEL. Which, I thought, was a major contributor to the oil consumption problem I was having. Its got about 215k miles on it now.

It appears to be using about 1 quart every 1500 miles. I do think it could use valve stem seals being replaced but I've never done anything like that so I don't really know where to begin or to just send it out to my mechanic to replace them... Anyone know how much that would cost?

Here's some of the engine related work according to my documentation:

214k = Replace Cam Oiler Clips
208k = Replace Timing Chain and Guide Rails
150k = Replace Left Cam Shaft and Rockers
137k = Replace Timing Chain, Timing Chain Cover Seal, Right Bank Headgasket

At 215k, I would think maybe its due for some head work?

As usual I appreciate your comments and thoughts.
