Next on the list was to set the valve clearances up and replace the valve cover gasket as it was leaking. The p.o told me that the valves had never been set, and Mercedes recommends it be done once every year/12,000 miles. Pretty easy job, had to modify a pair of wrenches which was the hardest part of the whole job. Seven of the ten valves had no clearance, afterwards it ran much better and sounded much smoother, and there was even a small but noticeable increase in acceleration...
Almost no wear on the cam lobes...
No gunk in the valvecover either...
Then it got an oil change, oil/fuel filter, air filter. There was a mixup with the oil filters, apparantly there was a change mid model year in '75/'76, and the oil filter changed size. The one in the picture is for a '76, but it is far too long. I ended up going to Mercedes for an oil filter and air filter, and was suprised to find the prices were actually cheaper than the aftermarket stuff...
I've put 900 miles on the car in the first two weeks I've had it on the road, and the oil level has not moved on the dipstick. I'm impressed
