so where on the 5.7 can i inject the seafoam? i know on later model 5.3's i gotta find a intake vaccum tube and inject there. i was almost thinking just take the intake off the throttle body and spray into the manifold that way. whats some advice on this?

Brake booster line works great, only problem is that is doesn't get into the front 4 cylinders all that well.

What worked for me was to raise the right side (drove up on a dirt pile) and use the vent hose from the right side valve cover. I just turned the hose upside down and poured the seafoam in while it was running. I would pour until a slight bog, let it recover and do it again. I pulled the intake 3 weeks later and it looked great, including the front cylinders.Originally Posted by 98GreenMachine
