Well the ignition coil was my fault. I made an engine monitor which I hooked up to her car to test. Thus I taped into the negative side of coil to measure tachometer. Well the wires for engine monitor ran beside seat and chafed such that the coil wire shorted to ground. This heated up coil and caused premature failure of coil. FYI the engine monitor can be seen at http://www.sterntech.com/pulsar200.php
I have not heard the end of that one yet as than in the manual for the engine monitor I recommend placing a low amperage fuse in the tachometer sense wire such that if the wire shorts as it did on her car it will blow fuse and engine will still run. I am also to blame for the valve body as that I was the one who rebuilt the transmission last, but that was about 20k miles before that problem happened. I am also to blame for the brushes as that I did not know to check them. I have discovered that they tend to wear out at 170k miles and have kept several other people from similar fate, but... Now the water pump, I might have to blame Mercedes, there was no noise leaks or anything. Going down interstate at 70MPH and it locks up solid, burnt both belts off in matter of seconds. However since it was full of coolant we were able to get off at next exit and call for tow truck. Working on cars for over 20 years and it is the only water pump I have ever seen just lock up. I have seen vanes rust off, vanes come disconnected from shaft, etc (on non Mercedes) but never one lock up with out leaking or bearing making noise, etc. Regards, Trampas -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Kaleb C.
