1991 300e, M103. Finally getting around to putting the head back on. First Benz i've owned, so still learning the tricks. Trying to get the cam gear back on the cam and I don't have enough chain slack. I removed the large allen cap that holds the chain tensioner, the spring came out, but the tensioner shaft only moved back approx 1/2 inch max, and will not move any further.
