Is the valve stem in question at the same height as the other one when the valve is closed? ie is the seat loose and holding the valve intoward the piston a little?
Put #4 on tdc by hand if it gets tight stop. If it goes to tdc do a leakdown test or just put air pressure in it to see if it will hold a seal at the valve seats. While it's there check for the valve clearance to see if it's right if it's not maybe the adjuster backed off. Make sure the pushrod is in the center of the lifter if the adjuster backed off before you readjust the arm. Compare the intakes and exhaust adjusters to see if they are approximately at the same position to see if the one in question has loosened up. When you put it back make sure the pushrod is centered in the lifter. It will go in a little farther when it is in the center. |
