Since changing the oil and valve gasket, and seafoaming, my 97 cavalier has developed a metallic sounding tick at idle. If you listen close to the valve cover, you can hear the rest of the tappets. I honestly cannot tell if the sound is coming from the valve cover or back by the intake manifold. I will try to record it in a few minutes to post it. My grandfather said with 10W-30 it ticked for a while a long time ago, but it hasn't with 10W-40, which is what I put in it. the only difference is that the new oil is Valvoline Maxlife, the old was ACDelco Dino oil. I also seafoamed. So do you guys think it will be an injector or a valve tappet?
