this last video is a little lengthy but interesting to watch especially for individuals who don't have a real good understanding of how an engine works. You watch these videos and certainly can appreciate the abuse we put engines through and only makes sense to buy the best components you can afford.

by the way who manufactures clear valve covers?

cool stuff. Heres one that shows the importance of proper rocker geometry. And how it can kill lift at the valve , as well as duration/ratio at the valve.

I caught that one also. I'm glad I don't have see through valve covers. Think it would freak me out to much. Is kinda cool to see though what goes on in there.

I think the first video was a dodge R6 race engine, I've watched alot of UHFR videos of valvetrains . The things that happen to a valve train at 8-10000 RPM are unbelievable
Its amazing that they will stay together as well as they do.

I woke up on the floor after an epileptic seizure after watching that second one! :p
