So let's say you were changing some cracked hoses and accidentally snapped your car's PCV hose nipple. Question is: What would happen? Your car would not only smell like oil, but it would also lose its vacuum. Without a PCV hose nipple, your engine won't run as efficiently as you'd like it to even with a newly installed PCV hose. Read on and learn the steps to replace a PCV hose nipple and your PCV hose as well.
Tools that you'll need:
- Jack stand
- Ratchet and socket
- Hose clamp
- PCV hose
- PCV hose nipple
Step 1: Place a jack stand beneath the lower control arm of your car and make sure it is secured. You will be working under your car so make sure there is enough space to move around.
Step 2: After locating the PCV system, detach the clutch cables as to avoid damaging other parts. Loosen the hoses connected to the valve. Also locate the PVC hose and then the PVC hose nipple (which actually protrudes from the side of the oil pan).
Step 3: Use a hose clamp to move over one end of a 3/8-inch hose, and push it up the hose so that it does not fall off. Move one end of the long hose over the PCV port tube until it fits the side of the oil pan.
Step 4: Move the hose clamp to the end of the hose near the base of the oil pan. Using a 3/8-inch drive ratchet and socket, secure the clamp between 15 to 20 foot-pounds of torque. Insert the entire tube to the back of the driver's side of the engine.
Step 5: Cast the front of your car down and raise the hood. Find the PCV valve on the back of the valve cover (which is the uppermost part of the engine, directly on top of the block) and join your PCV hose to the long PCV valve by hand.
Step 6: Attach the PCV hose to any plastic clamps or brackets that are designed to hold the PCV hose securely away from the extremely hot parts of the engine.
Step 7: Fasten the upper end of the hose to the nipple on the intake manifold. Do this also on the other end to the top end of the bottom portion of the PCV hose.
The entire process of replacing both the PCV hose and PCV hose nipple can take a few hours. If you have time, check the whole PCV system in case there are other repairs that need to be done.
