Ok fellas here it is.I took the headers off to put an other pair on and I took the valve covers off to put new valve springs.I did the drivers side valve springs with no problems,but the passenger side last 3 I could not get the spring compresser in their because the a/c box is to close.I tried to compress it with a long screwdriver which did the job on the #4 cylinder exhaust.Long story short I cut the air compresser off by mistake,and dropped the valve in the cylinder.I can feel it through the exhaust port, I tried to angle it to push it back up but could not.Question is can I push it back up with some needle nose plyers or not or do I have to take the head off.
