You mind as well have him check the timing chain, tensioner and guides while he is in there.

I've read in other posts about a coolant leak from the rear of the engine passenger side "common" on my engine. Ther eis no mixing of coolant and oil which is good and I do think i could drive for another 10-20K miles in present condition. However rather than push it off and chance an overheat possibly warping the head I wouuld do the right thing and have them change the gasket. Everything else at the shop tested fine so I assume the valve guides are not in "spec" anymore. They didn't give me the size. I will ask though.

Want to put a tank in the trunk for WVO/SVO in the E300 Need to find a place to store my OIL! 
Still procrastinating about the biodiesel/WVO 
Made some biodiesel but so afraid to pour it all in - I've added some and think I'll supplement my fuel to see how I make out 
Made some biodiesel but the process scares me - methanol fumes are not your friend! Need to do this outside.
