The intake valve is bigger.
The intake valve is bigger.
The intake valves are in the intake ports, the exhaust valves are in the exhaust ports.
can't tell much from the question but if you want valve clearance setting it is .002in. on the intake and exhaust valves
.006" intake and .010" exhaust
intake valves are the larger valves or if you count from from either end its number 2,3,6,&7 valve
if the spark plug wires go down the middle of the valve cover, it is DOHC. The Intake Manifold will also say Duratec. The OHV motor will have the spark plug wires connecting on the bottom of the head near the exhaust manifolds.
no you cant
Real simple exhaust camshafts are the camshafts nearest the exhaust manifolds ( outside if cylinder heads) intake camshafts are on the inside closer to center of engine.
Which kind? Exhaust or intake, run a compression test. A burned valve will show up as low compression on one cylinder. A blown head gasket will often show up as low compression on TWO cylinders. If you suspect a bad PCV valve, jsut replace it as part of the tune-up.
26mm inlet 22.5 exhaust
use a piece of modeling clay,( you can get any wal-mart craft section). place on top of the intake valve relief . place the head on the motor with a few bolts and with a week spring and your valve in place, compress the valve and measure the clearance with a dial indicator and this should tell you thickness of the head gasket you need.
Another simple way is the pcv valve is in the oil filler cap on the drivers side valve cover, as opposed to in the valley pan. 4 Round exhaust ports on the SD. Cylinder head code 16 (on center exhaust ports) Large distributor hole. LS2 ('73) or LS2X ('74) cast on intake manifold. Two letter stamped code on front of block would be one of the following: XD,JZ,W8,Y8
