Part of engine leaking from the top

Hi. I own a toyota tacoma 98 2.4L.
I changed my spark plugs yesterday and noticed something uncommon.
There's this part of engine leaking from the top. It's loose when i tried to move it. Is it common in these models or i'm having some kind of problem with it? Thanks.

 

Have you figured it out? If not try the technical section. Sorry I can't help you out with it. Good luck.

 

Is it on top of the valve cover? Looks kind of like a PCV valve???

I dont own a first gen.. cant offer much help

 

it looks like the PCV valve--there should be a HOSE connected to it.
On my 91--it would run rough and stall is it was not connected.

 

yes it is a little loose--you can move the pcv valve

 

oil vapor and spray will exit thru the top of the PCV hole

 

FIX it yet?

 

bump

 

I did connect a hose on it but it still keeps on leaking. Do i need to change it or it'll be fine like this?

 

Did you replace the PCV?
If not-pull it out and shake it--does it rattle FREELY?
If it does NOT rattle--replace it or clean it with carb cleaner.
Last time I replaced one--it was cheap.
Keep us posted on your results.

 

So i took it off and tried to shake it. it was jam. So i just got new one. It costs only $5. Thanks for the help.

 

You might look into replacing the rubber grommet that the Pcv valve slides into, might be old and brittle from heat and age. New valve and grommet you should be good to go.

 

EASY FIX-- Great job!!!
TOYOTAS are GREAT!!!!!!!
