Just curious if anyone has done the timing chain(and tensioner of course) replacement on the M103 engine. I've read thru the service manual and it doesn't seem to hard, the Haynes UK manual also states that the special chain press tool is unecessary and you can use a hammer and block to press the rivets into place. I've also discovered that I can rent the tool from IMPCO if necessary(seems better to me) My big fear of course is that the chain will slip on installation changing timing. Anyone done this??? BTW thanks to all on the handling posts. Going to replace those rear thrust arms very soon.
