You got to have the "special valve adjusting wrenches", I've never tried without but it's a no brainer.Max

[diesel_mercedes] A sad day in Beantown

 

"Click and Clack," the mechanics-turned-comedians who launched one of the most unlikely -- and most beloved -- talk shows in radio history, have decided that 35 years at the wheel is enough. Brothers Tom and Ray Magliozzi announced Thursday afternoon that they will no longer record new episodes of the weekly call-in series, but it will continue to live on in syndication.

[diesel_mercedes] Re: Trying to make right wide angle mirror.

 

PO put cheap peel-n-stick convex mirror on my right hand mirror and I have used it for a number of years without problems.

A neat mirror glass for both sides used in Europe is a "double convex" that is sort of a bifocal, where the outer inch or so of the mirror glass is canted outward. You get a very wide field of view with these. Works great. Just need to find a part number for them.....

Even so, the valve adjustment is still fragile. Maybe I'm just a klutz, but I've had a diesel Mercedes since 1976 and adjusting the valves has always been a challenge to get them just right. On some of them I will get the feeler gauge just where I want it, then I will very slowly tighten down the nuts and re-check only to find the damn thing changed, some I end up doing several times to get it just right. It's a easy job(except on turbos ,seems like one valve was a real pain) just takes a lot of patience. I would bet never using Nate's "stepped" feeler gauge, that it would make the job easier.

Re: [diesel_mercedes] Follow Up 300 SD Miss

 

Bill, 
 
    I think that Nate, and probably others, posted responses telling you that the valve adjust is the FIRST task on these engines.  You said "I'll get around to it, after doing other stuff that I consider important." 
 
    Perhaps there are lessons here: 
 
1)    For other newbies to these engines, the valve adjustment is an important, priority task; 
 
2)    For all of us, there are plenty of people here who really KNOW what needs to be done.  Their advice is important and valuable. 
 
    As to the sensitivity of the adjustment nuts - there are specialty tools for this, which are essentially wrenches that have been bent to fit the odd spaces.  Some people here have made their own, out of regular wrenches.  Such wrenches make the job easier, including holding the nuts in place as they are tightened.

I was impressed with the general appearance of the top of the head, valve cover and cam lobs. Actual it was spotless clean. Most vechiles this age, that have not been overhauld, would be full of crude. Regular oil and filter changes does make a difference. Bill C
