PCV vacuum hose location??

[selvatico]

Hello, can anyone take a pic or point me to the location of the PCV vacuum hose in an 03 Pilot?

I have a lot of carbon build up in the intake manifold and would like to use seafoam, but i want to make sure i use the correct vacuum hose.

any help will be greatly appreciated.

Thank you,

Pete

Looks like the valve should be in the rear valve cover not too far from the throttle body.

If you're Seafoaming it, use the brake booster hose too.

#3 & 7 are the fresh-air tubes from the intake arm to the front cylinder head (before the throttle body).

#1 & 2 are the polluted air suction line into the intake manifold. #2 is the PCV valve and it just plugs into #4 rubber grommet in the top of the rear valve cover.



If your getting a lot of oil into the intake manifold, you could consider splicing a catch-can to in the middle of the #1 hose. A good baffled catch can will separate the oil vapor from the air and collect the liquid, while only the fumes continue to the intake manifold to be burnt in the cylinders. Unfortunately most catch cans are vented to the atmosphere so you would have to find something with a line in AND line out (no breather filter). Lots of people use a simple filter/separator for compressed air lines from the hardware store (~$20). Just remember to empty the oil from the catch-can when you change your oil.



BTW: I would not feed that Seafoam crap through my throttle body. Personally I would try using the purge solenoid hose (one with blue clamp in pic below) that connects to the top of the thorttle body for good distribution of the chemicals to all cylinders. The PCV intake hose doesn't have much suction since it's before the throttle plate and not under vacuum....AND you do NOT want to wash all the lubricants out of your throttle plate. This could lead to a sticky throttle years down the road. The throttle body is not meant to have chemicals flow through it.



PS: I've used that crap on two different vehicles and both times it killed my O2 sensors. :/
