[MBZ] Adjusting the valves
I finally got to work on this poor old car and pulled the cam cover off and started on the valves this weekend. I ran out of time so it is sitting in the garage waiting for me to come back to it. I have 3 valves left to adjust. The intake on 4 and on 5 and the exhaust on 5. I sort of got stalled out on the exhaust on 5 as it is very tight to work in there. The valve is up against the cam tower and the wrenches are long enough that they bump into a support from the firewall and a wiring harness. I have been digging around for some other wrench that may work better. I have a short 14 mm and will try it next. If that does not do it, then I may be looking for a junk 14 mm to see if I can modify it some. All of the valves so far have been tight except for one. The intake on 1 was on spec at .004. The exhaust valves should be .012 but have mostly been .009. The intakes are supposed to be .004 but are too tight to read with a feeler gauge. Turning the engine over by using the nut on the end of the power steering pump worked fine after I figured out how to do it. The pump is mounted low on the driver's side of the car so there is not much room to reach in. I have a fairly long 22 mm combination wrench and it worked on the box end but not well due to the angle of the handle. I mucked about trying other wrenches like a crowfoot on a breaker bar but nothing really fit. I finally tried using the open end of the wrench and it worked fine. A bit slow as I can only move it a bit and then have to re-set the wrench but not too bad all things considered. I just did the valves in the order that they came up on the cam and not in number order so I did not turn the cam any more than necessary. I hope to do the last 3 this evening so I can put it all back together. The only disturbing part has been that something appeared to fall between the injection pump and the block. I have no idea what as I did not see what it might have been and have no idea what might be missing. I see nothing on the floor under the car and I can see nothing in between the engine and the pump. I will fish around with my magnet but since I don't know what I am looking for, I don't even know if it might be magnetic etc. Perhaps when I put it back together, there will be something obviously missing.

Re: [MBZ] Adjusting the valves
I got a couple of cheap India wrenches at HF or a pawn shop or something for like a $USbuck apiece and put the torch to them to bend them to the proper angles to do the job easier. If you have a tight space you could cut one down too. I had done the job once before on the 300TD with regular wrenches and it stimulated Foul Oaths; whereas, the bent wrenches made it a lot easier the second time I did it. --R On 7/14/14 3:54 PM, Randy Bennell via Mercedes wrote: I finally got to work on this poor old car and pulled the cam cover off and started on the valves this weekend.

Re: [MBZ] Adjusting the valves
I have the special set of bent wrenches bought from Rusty years back. They work fine on all the valves but this one. May have to see what I can bend to work better on it.
