Answer 1

where is the pcv valve located on a 2003 Toyota corolla?

This does not help! 4 0r 6 cyl? either way the pcv (positive crankcase ventalition) valve is located on top of the valve cover(4cyl) or on one of the valve covers(6cyl) it has a pre-bent black hose from a vacuum source to the valve. if there are some miles on the car you will break the valve and hose(due to being brittle) how ever no worries, simply replace valve and use 5/16 fuel line to replace the pre-bent vac. hose. you may have to tie strap at both ends to keep the hose from coming off. the valve helps the engine from building up too much pressure resulting in oil leaks. good idea to change at tune-up time, but over looked by most techs. good luck. master tech 26yrs
