I am working on my 92 300D, 233K miles. I was having the ruff idle until it warmed up problem. I pulled the injectors and had them rebuilt. I the checked the timing chain stretch, it was 8 degrees. I ordered parts and rented the crimp tool and A B light timing tools. I had experienced help set up but family issues has held him up. I started in on my own so I can get these tools back. I rolled in the new chain, then wired both ends out to the sides to change the cam gear. The wire to the right chain end (drivers side ) broke and the chain slipped back. To add to my woes the other side slipped but didn't come all the way off as I am trying pull the right side back in place. I thought I got it right back where it was, on cam sprocket. The master link is put in but not crimped and the tensioner is still out. When I turn over crank to line up the cam marks I am at 15 degrees after TDC on the crank marker. Could the fix be as easy as taking master link back out and rotate crank backwards to move chain down a cam tooth at a time until crank matches up with cam lines. Or can I turn it backwards ? Would I have to roll in the old chain , then the new one again to keep it going in direction of engine rotation? I am thinking the cam lines/TDC has to be lined up while turning to the right or down with ratchet so all the slack is on the tensioner side. I have messed up here but If I can get my head straight on how to redo this, I think no harm has been done yet. Thanks for any help, Charlie Klippel
