Today I was toying under the hood of my car. When I took the rubber hose that runs from the valve cover from the throttle body off it had a lot of chocolate milk looking oil in it. I went to look at the dipstick and the oil on it is a normal color. The car has been sitting for about a month and a half because it gets stored for winter so I was wondering if this could just be condensation inside the engine mixing with the oil?? Thanks

 

Run it up to temp, then check the coolant for the same milkshake as I call it.

 

Simple solution. Stop pouring milkshakes in your engine.

 

 

most likely just condensation, let iy run for 30 minutes or so and check your oil, if ok, just condensation,

 

While you're at it, check the PCV valve on the driver's side of the intake manifold. In a correctly functioning system, the PCV valve pulls air through the line from the TB to the valve cover, through the crankcase, sweeping out the blowby. The combustion gasses contain large amounts of water. If the PCV valve isn't functioning, the crankcase gasses start to flow backwards, out that hose, where the water will condense.

Might be an indication of a plugged up PCV valve, or it might just be the result of the engine not being heated fully to operating temperature the last few times it was run. If you are running it briefly during storage, you might want to not do that, unless you can insure the engine, including the coolant and the oil, will reach full operating temperature before you shut it off.

 

Im not stealing the thread, but can the PCV valve be cleaned if it is plugged up or is it better to get a new one. Easy to install?

 

Very easy to install, and only a few dollars (no tools needed). Don't even bother cleaning it.

 

I would have taken milkshake over sparkleing glitter nail polish.

 

Yes the PCV valve can be cleaned with solvent ( I use chem tool) after cleaning shake it it should rattle freely. Also check your PCV hose for kinks and such that could limit the airflow.

If you have a short morning drive and the motor doesnt get to full operating temps then you'll see alot of condensation in the tops of the valvecovers and the PCV system. If the milkshake isnt on the dipstick its just condensation.
