HELP!
while attempting my chain/guides replacement...
I managed to round off one of the allen bolts that holds the alternator to the block. The guide rail pins do not want to move...I broke a bolt in a pin using the bolt and stacked washer method of removal. I am so close yet so far from getting this job done! Any suggestions as to the removal of the allen bolt...of course it is the lower most/ hardest to reach one.

 

I would try a right angle drill and an "easy out". Be careful not to break that off though. It is hardened and almost impossible to drill.

 

can also pry off the cover. the stud would eventually come out together.

 

I got the last allen out by jb welding the allen socket to the bolt. The guide pin is now a solid piece with the extractor broken in it. Now I really need some help. The passenger side has new guides (old ones look just as good as the new ones except they are more yellow/ orange in color)
Single digit IQ here don't understand.

 

Howdy--I'm new to the MBZ Forum and I'm wondering what you found out regarding the wisdom of replacing the timing chain & guides--I have no problems yet with the chain or guidesbut my car <87 560 SEC>,has 167,000 miles on it.
My mechanic said it's about a $1300 job....ouch!
