Have a 1998 saturn sl2. It has the DOHC. Been dealing with noise problem for a while. I have a loud ticking/rattling sound coming from under the valve cover. More towards the left side while looking at the motor. One friend thinks it has to do with timing chain and one thinks it has to do with the lifters. There is no loss of power and it runs fine. So I think it can't be timing chain. We put some of that engine oil cleaning stuff in and it did quiet just a tad. I also did some research and read something about Saturn generation 1 lifters start to make noise around 70 - 80 thousand miles. I have 80. Any ideas? Thanks.
