I know most would say lifter or rocker coming apart...heres the deal. Never noticed this until a few days after I did an oil change w/ penn. platinum. It makes the tap/tick after driving awhile when the cars warm. I had a friend tear into the car and everything looks good. Im not exactly sure what weight I used before but he reccomended that it might be the oil(something about companies sometimes making the syn. oils to thin). I have a amsoil race syn. going in today. How many think this might be the problem?

i had a noise coming from mine it was stronger under the car and kinda sounded like a exhaust leak , everyone told me piston slap , bent valve , broke rocker collapsed lifter i dont head cam lifter swap and it still done it i finally got tired of listening it and tore it apart and found the #7 rod bearing wore out and loose. mine was noticable when there was a slight change in rpms idleing down or holding steading sometimes but not in the upper range or at idle

Last oil change I used a fram filter...did a search and was reading that they only flow half as good as the other brands...Could that be a possibility?

This is really ironic, because i changed my engine to penz platinum also and the tick started to occur, i then went to Royal Purple to than find out that its complete garbage, so i went back to Mobil 1 with an additive. The tick noise quieted down a little bit. But i have a bad tick noise in my engine, seems like its coming from the left side (if your looking under the hood) valve cover. IDK what it is maybe lifter/rocker... Sorry to hijack your thread didnt mean to
