I use Seafoam in my daughter's 2000 Volvo and inject it using an air intake hose near the air filter box....direct injection into the engine.

Is there a way (a port or breather hose) that can be used on our cars to do the same? Not interested in doing it through the gas tank....wanna do it by having the engine suck up about 4-5 oz. into the intake system.

Anyone know of a procedure? Tried "Search"...no help.

Thanks.

 

try brake boaster hose.

 

I use the hose coming from the front bank of cylinders which is part of the PCV system. It distributes air relatively uniform among all cylinders. The 4G TL and 2G RL have different versions of the V6 but I believe the PCV hose that goes from the front bank to the intake manifold would likely be present on your engine.

 

Ace hardware sells plastic hosing by the foot. I ended up buying some hose from them to make my own that I could attach to the brake booster since it's nearly impossible to grab the brake booster hose on the side where it attaches to the booster.
