If the exhaust valve is on the #3 cylinder (driver's side, frontmost cylinder), it is the one that gets the hottest in the aircooled VWs. It is also the one that is most likely to burn or get 'swallowed' (broken off and being rammed by piston). Usually sticking is caused by the valve guide being worn, so pulling the head is mandatory. Assuming it's really stuck open and not burned, here's something to try. Put the offending cylinder at Bottom Dead Center (farthest away from the valves), remove the valve cover and tap the stem of the valve with a plastic or brass hammer, or piece of wood between a regular hammer and the valve stem/spring retainer. It may pop back up. Turn the engine over by hand to see if it sticks again.
The intake valve is bigger.
Exhaust cam, is the cam that control valve timing on a DOHC, (DUAL OVERHEAD CAM) motor.
The Exhaust Gas Recirculation Valve on a 1989 S10 is located in the valve cover. It is toward the front of the motor.
Intake 25 Exhaust 30
Yes, usually when it is cold and needs more fuel to start. If the valve is hung open, exhaust floods the cylinder.
Sounds like a burnt valve, the gas is not burning because of no compression due to burnt valve and gas is pushed out of exhaust unburned
Intake- 0.20 exhaust- 0.25
The exhaust valve is always smaller.
The lifters are hydraulic and require no adjustments. If you have valve clatter you have worn valve train parts.
.2mm for intake and .3mm exhaust. or .008in and .012in when the motor is warm. not sure for cold motor.
Exhaust coming out of the airfilter indicates a possibility of a few things. Motor has jumped time. Burnt Intake Valve It can also be that the valve lash is out of adjustment.
The exhaust valve gets hotter than the intake valve.
.006 intake and.008 exhaust
look at the head with the valve cover off find where the exhaust manifold goes in tha is the exhaust valve or looking at the valves the first one is exhaust then intake then intake ,exhaust,exhaust,intake,intake,exhaust if you have the head off i think the intake valves are bigger than the exhaust
Most probably a loose tappet. Check the valve clearances. Or a valve could be sticking in its guide.If the lifters are hydraulic (unlikely on older cars) they might be gummed up. A good flushing oil will clear sticking valve and lifter problems.
The intake valve is always larger than the exhaust valve. It's just physics.
The exhaust lifters will line up with the exhaust manifolds,Remove the valve cover if your working on a V8 and the valve that lines up with the exhaust port will be the exhaust valve,If it is a Chevy V8 they will be from standing in front of the car exhaust,intake,intake,exhaust,exhaust,intake,intake,exhaust.
Valve clearances are measured with feeler gauges on cold aircooled engines or warm water cooled engines.
intake valve is bigger.
fan cycling.3 way modulating valve
We currently have a 6X4 Gator with an eighteen hp Kawasaki motor. OUr motor number is FD620D. This number can be found on the front engine cover. The valve clearance for both intake and exhaust is .010"
need to no if the first valve is intake or exhaust The intake valve is always bigger than the exhaust valve.
Look in the back, behind the motor on the right side. It looks like a screw sticking out.
the egr valve is sticking open and causing the motor to surge replace the egr valve and the problem will be solved
It's an exhaust break, it uses the engine compression to slow down the vehicle by putting back pressure back in the motor. It's essentially a valve in the exhaust that closes.
