Hi I am new to this forum and have a few questions. I just bought a 1990 325i, and took it to a mechanic to check it out. He said that he should look at the timimng belt and see if it should be replaced. I was wondering if anybody has ever changed a timing belt, and the skill level of the job. I realize that if i screw up the job my engine could be in jeopardy... so i am a little hesitant to take on the job, and might just have to fork over he money to have a real mechanic do the job. Thanks!!!!!
