    I need help locating the PCV valve or the break booster line, going to be running seafoam thru one of them. The engine is in a 2005 Silverado, 4.3L V6.

    Thanks in advance,

    The brake booster is the large pancake shaped can between the firewall and the master cyl. The large diameter vacuum hose fron the intake connects to this can. It can be removed at the booster end so you can slowly pour in the seafoam...

    I'm not sure if the later 4.3L have PVC's, at least the later versions inthe S-10 didn't have one.
