Well, finally changed the rattling clicking lifters in my 1997 sunfire today. Seven hrs work in the garage. It was worth it though. Before, I had hard starts and I could only rev the engine to about 4000 rpm in 3, 4, and 5 gears. I can now get 6000 rpms out of it, and it has way more power. The lifters were making noise only when the engine was cold. Sometimes louder than others. They looked like new when i got them out, but they must not hold pressure or somthing. Just wanted to post this, because I couldnt find much info out there on the noisy lifters. My arms are all bruised and scratched up, but im glad it wasnt a V6.
