s13 PCV Valve

[lenso]

i bought a pcv valve so i can pass emissions but i'm not sure where it is. i did a search and found that its behind the throttle body. one fix was to replace it, the other was to spray carb cleaner to clean it. where do i spray the carb cleaner? i would much rather clean it then replace it cause I don't want to get new gaskets for the intake manifold.

you dont need new gaskets, it is a bolt looking thing sticking out of the side of the metal box that says eccs on it. mine was rusty. and the pcv valve is about halfway down. ask if you have any trouble and ill scan up a pic

Lenso, I'm assuming you've a DOHC and yeah that's a hard one to get at. Perhaps this will guide you on your way.

OMG, just got done replaceing it, talking about a PITA!! I think a motor swap is easier, may take more time, but easier. What I did was take off the intake, the throttle body, the coolant lines that runs into the thermostat housing, bend a few pipes around to get at the PCV valve, got a long 19 and a short 19, take turns swapping between the short and long 19's to get the PCV to turn bit by bit. Then once off, put in new PCV and reverse the process. My throttle body gasket broke in half so I had to use some RTV silicone maker. Just spread a thin layer on the throttle body and bolt it back on, open the throttle body and wipped off all excess inside the intake manifold. Done! Well this is for anyone who is interested.

would i have to buy new gaskets when I remove anything? thanks for all the replies!

nope, only if you remove the intake manifold do you have to replace gaskets, and your not taking that off, so you should be fine.
