I am trying to seafoam my buddies corolla. But cant find the vac hose. How do I inject seafoam into the engine?

I will also be doing his plugs and filters. Along with oil change.

Any good places to look for basic corolla maint. I tried lookin on google for seafoaming corolla and no luck.

How do I seafoam a POS toyota.

if you can't find the vac line - you probably shouldn't be doing this. :troutslap

Find the charcoal canister, thats a vacuum line connected to it.

From Autozones website, this is what it should look like:

maybe I will jsut tell him I seafoamed...

Look for a rubber vac line attached to the intake somewhere (without a sensor between it) and use that.
