I have a 2003 Corolla with 143,000 miles. When I start it in the morning it rattles like crazy. I took it to my mechanic and he said it's coming from the cam. He thinks it's either a worn cam or clogged oil journals. He said he does not recommend trying to clean the journals or it could cause the clog to move which will lead to engine failure. At some point I plan to have him take a closer look, but I was wondering if anyone had any thoughts on this problem. I've been driving Corollas since 1980 and have never had this problem.
