I'm looking at a nicely priced GenIII and I was curious if the engine sometimes has a tinny upper end noise (haven't heard in person, yet) if that is a pending or slipped cam sprocket type noise? They told me that it goes away when its warm. How safe would it be to drive the car for a few hours to a shop so a weld could be done? They say the engine runs really well right now, but if I'd purchase the car I know I'd want the cams welded... It's just a really good price and it's not too far away. Any thoughts? I'm only seasoned with my knowledge of the V6 MTX.... Also, does anyone know if Performance Plus still does cam welds? or another competent shop in the SE Wisconsin area?
