Special tools are needed but you can still run into problems  
			When working on engines 30 years and older you can run into some real challenges. This is typically the case when attempting to do a valve adjustment. This applies to almost all four and six clyinder single cam engines as well as the early V8's from the late 1950's up to the mid 1970's
