1.8 Rockers lame question
What does it mean and do I have these on my 02? Is it a ratio of some kind of the rocker arm? Was looking at a camshaft to buy and it says it won't work with 1.8 rockers. Thanks

The stock ratio is 1.7, if you change to a 1.8 ratio the valve lift will increase about .030". That's why you need to get the approiate cam for the rockers you will be using. Otherwise you might run into a coil bind or piston to valve clearence problem.
