Changed my spark plugs and found this.

[JB_Runner]

This was my first time ever changing my spark plugs or even around a wrench. I've decided to take it upon myself and with the help of all these write ups to tackle this task.

So as I took off the intake I noticed that there was oil in the tube and I don't know where it is coming from. Can someone please help me out and shed some light on if this is normal or a major problem. Also would I be to do it myself or take it to a mechanic.

Looks like it is coming in from all that noise reduction stuff I eliminated under my hood. Its 2am and I can not remember part names atm but if I remember right that runs to a tube that goes to your valve cover and there is a valve at the end. I want to say EGR valve but my brain wont click. Ether that valve is toast or there is anther problem sending oil past the valve covers and up that tube.

PCV Valve I believe

Change the PCV valve first. Looks like blowby. May have bad valve seals.

Loosing any oil between changes?

What he said. Change the PCV valve (they're cheap). If it's bad (or gunked up) pressure in the crankcase will blow oil out the crankcase venting intake tube (the hose to the valve cover) and into the air intake tube. It could also be blowby from really bad rings, but most likely it's a bad PCV valve.

Another for PCV replacement but make sure you get one from Toyota. It's less than $10 and is much better quality than ones from ze Botozone.

That's usually a sign of excessive blow by of the cylinder(s)... if the PCV valve was bad it would be puking oil out of other areas or basically wherever gives out first.

@litteCaesar yes I'm losing some oil between oil changes.

Also are there any write ups on how to change the pcv valve anywhere?

Edit: the pcv valve is held in by a rubber grommet, just twist and pull. Its fairly simple and shouldnt take more than 2 minutes.

Thank you.

Does anyone know the part number?

The # is: 12204-62010.

Change it (may have to give a hard tug to pull it out), then top off the engine oil until it reads full. Drive 500 miles or so and see then if you have lost any oil. Report back.

If none is lost, then the PCV was clogged, or just lived past its life expectancy.

If you lose some oil, or see it back in the tube, I'd then check for possible blue smoke coming out of the tail pipe when it is first cranked in the morning (indication of oil getting past the valve seals).
