[john walker's workshop]

the year of the car is helpful when you post. 80-83, you really are better off doing it with the engine out. up to 79, it's not too hard in the car, but lowering the engine makes it a tad easier. account for every nut and washer and check down each intake to be sure nothing went in, and rotate the engine a couple times to check if anything slipped through an open intake valve. install the breather hose to the vent cap before slipping the intake assembly back in if you do it in the car. remove it as a complete assembled unit and reinstall the same way.
