Should the pcv move in and out not stay place a little oil come on 1989 Chevy S-10 Tahoe Blazer?

The PCV (Positive Crankcase Ventilation) valve should *slightly* move in and out – it's a valve, not a completely sealed diaphragm. A small amount of movement is normal during engine operation. However, it shouldn't be moving excessively or staying completely stuck in one position.

Oil coming out is definitely not normal. This indicates a problem. Possible causes include:

* Faulty PCV valve: A stuck-open or severely clogged PCV valve can cause excessive crankcase pressure, forcing oil out.

* Worn or damaged PCV valve grommet or hose: A leak in the system can also allow oil to escape.

* Excessive crankcase pressure: This could be due to other engine problems like worn piston rings, a blown head gasket, or a failing valve cover gasket.

* Oil level too high: Overfilling the engine with oil can increase pressure in the crankcase.

What to do:

1. Check the PCV valve: Inspect it for free movement. Gently try to push and pull on the valve. If it's stuck or doesn't move freely, replace it. This is the cheapest and easiest thing to try first.

2. Inspect the PCV hoses and grommets: Look for cracks, holes, or looseness. Replace any damaged parts.

3. Check the oil level: Ensure it's within the recommended range on the dipstick.

4. If oil is still leaking after checking the above: This suggests a more serious engine problem. You'll likely need to take it to a mechanic for a proper diagnosis. The problem could be significantly more costly to repair than just replacing the PCV valve.

Don't ignore the oil leak. Continuing to drive with a leaking PCV system can lead to further engine damage.
