The first commets refers to the fitment of 'performance' cams....in my experience they are the best way to ruin the way your car will perform
unless it's on the track.
Also you know how to fit a cam but not how to identify a knackered
lifter!!!!!!!!!!!!!!!!!!!!?
Lots of people die from smoking, drinking too much and running down the road in Black track suits at night so whats your point?
