4. Carefully disconnect vapor lines from NVLD assembly.
5. Lift tab on NVLD assembly and twist assembly
counterclockwise.

plunger is only pulled part way back from inlet. This
results in maximum vapor flow through the valve.
DIAGNOSIS AND TESTING
PCVVALVE-3.7LV-6/4.7LV-8
1. Disconnect PCV line/hose (5) by disconnecting rub-
ber connecting hose at PCV valve fitting.
2. Remove PCV valve at oil filler tube by rotating PCV
valve downward until locating tabs (2) have been
freed at cam lock (3). After tabs have cleared, pull
valve straight out from filler tube.To prevent dam-
age to PCV valve locating tabs, valve must be
pointed downward for removal. Do not force
valve from oil filler tube.
3. After valve is removed, check condition of valve
O-ring (1). Also, PCV valve should rattle when
shaken.
4. Reconnect PCV valve to its connecting line/hose.
5. Start engine and bring to idle speed.
6. If valve is not plugged, a hissing noise will be
heard as air passes through valve. Also, a strong
vacuum should be felt with a finger placed at valve
inlet.
7. If vacuum is not felt at valve inlet, check line/hose
for kinks or for obstruction. If necessary, clean out
intake manifold fitting at rear of manifold. Do this
byturninga1/4inchdrill(byhand)throughthefittingtodislodgeanysolid particles. Blow out the fitting with
shop air. If necessary, use a smaller drill to avoid removing any metal fromthe fitting.
8.Do not attempt to clean the old PCV valve.
9. Return PCV valve back to oil filler tube by placing valve locating tabs (2) into cam lock (3). Press PCV valve in
and rotate valve upward. A slight click will be felt when tabs have engaged cam lock. Valve should be pointed
towards rear of vehicle.
10. Connect PCV line/hose (5) and connecting rubber hose to PCV valve.
11. Disconnect rubber hose from fresh air fitting at air cleaner resonatorbox. Start engine and bring to idle speed.
Hold a piece of stiff paper (such as a parts tag) loosely over the opening of the disconnected rubber hose.
