The timing chain guides on my on my 1992 500E is made from plastic. it broke last week. As a result, the head had to be pulled to clean out all the debris inside the motor. It is a big cost. The garage where I took it to had worked on this problem quite a lot. My question is why mercedes would use such design approach. It seems to be contradicting to their philosophy of building long lasting car. The other question is is there a replacing part for the plastic guides? I'll ask my mechanic on this also.

Thanks in advance for your inputs.
