Can I change my timing chain without removing the front cover of that engine? and if not, can I remove the distributor drive gear with removing the cylinder head?

It can be done with a replacement chain connected to the old chain and turning it through by hand. The only reason to remove the front cover is if you need to change the internal guiderails and other plastic pieces, or if you are changing a single row to a double-row chain.

Do you have a service manual for the engine? I should think that you would want one before embarking on this job.

Good luck.

Here's a procedure for a 280 SL, M116/117 engine. It has some great photos and gives you an idea of what's involved. It doesn't cover ancillary parts. I just had mine done (by someone else). They did the tensioner and guide rails at the same time, which is highly recommended by our friends here. It cost me about $900 out the door, and only took a day to do.
