i looked in the helms manual and I couldn't find out where exactly it was. Any help? If I change the valve out, will i get back some of the lost mpg that I have seen lately?
Thanks

 

Its on the intake manifold.

 

You didn't mention which year and model Integra you have, but if you have a '94-'01 GS-R the PCV valve will be located on the backside of the engine block on top of the oil breather chamber. Here is a diagram from the Helms manual which show where it is located. Hope this helps you out.

 

Good luck getting to it. It is a PITA.

 

sorry i have a 94 rs with 122,000 miles on the clock. If i do want to replace it, where can i buy the part, honda? acura? autozone?

Thanks for the help

 

I would just buy it straight from honda/acura. Should cost that much.

 

it's where BSQ said...basically, it's on the back of the block on the passenger side of the stock oil separator can. You can replace it with a fram from kragen or autozone (it's as good as the stock one with a slight better flow rate).

Or you can get the stock one. They're under $5.

 

thanks for the help that is what i needed to know
