A friend of mind gave me a professional grade Valvoline Intake Cleaner from his shop. Can you guys show me exactly wear I am supposed to pour this cleaner, besides the fuel tank?


Thanks.

 

Can you post a pic of the bottle or link me to the product? I am thinking its similar to seafoam, in which case it would go in the vacuum line that runs of your master cylinder (the only black rubber line that comes off the brake booster).

 

The middle bottle here:




Can you tell me where I can find the vacuum hose on a 4ES?

Thanks

 

Army is correct, that should be injected into the intake manifold, at any vacuum line that will allow the product to be the most evenly distributed - generally right after the throttle body.

Here's one problem. That stuff is not designed to be injected into the engine in liquid form. There is a special tube system with a bottle on one end - looks kinda like an IV setup, and along that line, there is a open air vent - this airvent makes that fluid foamy before it gets inside the engine and makes it do a much better job of cleaning...

 

Thanks for the help guys.

So is it even worth using without that part? Or should I just pore it in the fuel tank, etc.?

 

Either put it in the vacuum line the way it is, or get a foaming spray bottle, pour it in and spray it in the open line. But I have never had any issues with seafoam in the lines in liquid form. Dump it in the lines, when the whole bottle is gone, shut off engine.

Wait 15-20 minutes, start it back up and watch the smoke roll.
