Default seafoam

I know there a lot of threads on the subject already, but I couldnt find one that has a picture of where the pcv hose is at? Does anyone have a picture of where to pour the seafoam into?

Thanks

easy.take off your engine cover. its on the intake manifold. its a piece of metal with a cap attached to it. take off the cap and u can use that as the vacuum source

Majority of the hoses are under the engine cover..Take off the engine cover and you'll see what you're looking for...

there is no hose. theres a metal nipple coming off the intake manifold. it has a black cap on it. remove the cap and slide your own hose over it.
when i seafoam my car, no smoke came out. i was disappointed
at least i know my motors good

i used seafoam on my 400 and smoked as well, but it did the trick i poured it in my gas tank, oil crankcase and pcv vacuum line. got rid of my rough idle and car feels normal again.

That's the "seafoam"

They also have the deep creep you can use in your intake manifold.
But be sure to split it into 3rd..and be sure the engine is 1/4 way warm..Also let it sit for about an hour instead of 10 minutes..Longer you let it sit the more time it has to work

hmm this seems like sum good stuff, but lyk the OP i would lyk to see sum pics on a gs before i attempt this. the gas tank n crankcase are easy but the vacuum hoses, seem a bit iffy.
