NO, they are the same. BUT you MUST mark them before you remove them so you can make SURE they are installed back on the same valve spring they came off of.
16 8 exhaust and 8 intake
V-8 engine has 16, 8 exhaust and 8 intake. V-6 has 12 6 exhaust 6 intake.
The best way to tell if the valves are closed is to observe the rocker arms. When they are both at the top of their travel, valves are closed. Feel the rocker arms and try to move them, if they move their at the top of their travel.
The pushrod is actuated by the camshaft for the purpose of actuating the lifters/rocker arms which, in turn, pushes open either an intake or exhaust valve in the cylinder head.
I replace the heads with first starting by draining the coolant then removing the exhaust as neccasary then the intake manifold and distributor then the valve rocker arms and pushrods then unbolting the heads.
On the v6, yes
The valve settings for a John Deere 7510 tractor typically involve adjusting the clearance on the rocker arms for the engine's intake and exhaust valves. Generally, the recommended clearance is about 0.25 mm (0.010 inches) for the intake valves and 0.38 mm (0.015 inches) for the exhaust valves when the engine is cold. Always refer to the specific service manual for your model to ensure accurate settings and procedures.
Rocker arms are set to a specific preload or backlash on v8 Chevies. There is no torque specification.
The rocker arms are not torqued to a specific setting. Follow the instructions in any repair manual for the proper method for adjusting backlash.
To adjust the valves on a 1992 Mitsubishi Eclipse, first, ensure the engine is cold and remove the valve cover to access the rocker arms. Use a feeler gauge to measure the clearance between the rocker arm and the valve stem, adjusting the screws on the rocker arms to achieve the specified clearance, typically around 0.008 inches for intake and 0.010 inches for exhaust valves. After adjustments, recheck the clearances to ensure they are within specifications, then reassemble the valve cover. Always consult the vehicle's service manual for specific torque settings and procedures.
