I appreciate your efforts as I am going to do replace my rails and chain ('84 380SE) this weekend as "might as well's" in conjuction with a camshaft replacement. I have studied both of your guides and feel ready to do it. I also have the service CDs, but their photos leave a lot to be desired.
One concern I have, however, is how difficult is it to hold the new chain rails in place as the new pins are driven in? There doesn't seen to be a lot of room for a hand and I shudder to think about dropping one down behind the timing cover. Or is it easier than it looks? Also, I am replacing the tensioner rail and tensioner just for good measure. Does the '84 380 have the electronic distributor timing control?
Even a broken clock is right twice a day.
