I've got it all apart, found that part of the compression issue is that the number 3 cylinder has a cracked piston, but also that the exhaust valve was burnt. So looks like I'm doing the bottom end as well.
How do I go about removing the valve guides? I plan on buying the head rebuild kit from 3tech and since it comes with new guides, might as well use them. Also any recommendations on where I can find new pistons that are inexpensive?
