PCV valve check ; Can it be done this

[Hershey]

Thanks CT . I have removed it before to check it and it seemed fine. Looks like I will have to give it the shake test again. Yes it can be difficult to remove. Probably best to do this when the engine is cold. Can you put duck tape over the hole while the engine is running to keep oil from coming out to give it the suction test?

Just try the suck/blow test. With modern cars it is far easier and less messy. I just pull the hose off of the EGR, stick a piece of clean hose (I have a 3' piece of fuel hose that I use) onto it, blow into the hose and the suck on the hose. You should not be able to blow, but when you suck it should resist a bit and then the ball moves and you can continue to suck.
