Hi Again 97 SL320,

Here's the update on my no start problem. It was the timing. I was off rotation TDC by 360 degrees and had the rotor pointing to #1 cylinder lined up with the wrong make on the distributor housing. After correcting my errors the car started right up. I removed the valve cover to ensure that
the #1 valve was closed on the compression stroke. Upon removing the cover I discovered engine sludge in the recesses of the cam bolts,
rust on one of the valve springs and almost black engine oil. This was an indication to me that the engine had not been run nor the oil changed in quite a while. I thought I would have to do a valve job due to the amount of blue smoke and white smoke blowing out of the tail pipe. I changed the oil, adding Sea Foam and Marvel mystery oil to loosen anything that might be stuck and move the sludge. The smoke from the tail pipe is markedly reduced and the engine runs much smoother. I'm hoping for a miracle that the oil that I found in the coolant when I changed the water pump also will be no more.
