Don't poor it into the line, let the line suck it out of a baby jar or something.

Just keep using it until no smoke comes out.

 

Safer to pour it.

One guy on yotatech dropped the PCV hose into the can of seafoam and wound up busting a rod and bending another. (along with the associated pins) after his 5vz-fe sucked the entire can near instantly.

Someone else lurking on here asked me a week or two ago how to unflood an i4 after doing the same thing.

So you definately want to pour it.

You have an i4. Put a funnel on a PCV/or BB line, pour a 2/3 of a cup into the funnel. Don't do it slowly, or you won't achive anything. Too fast and you might flood it out (hydro-lock it no... flood it, yes) As soon as the 2/3 of a cup is in the engine it needs to be cut off, and sit for 5 min.

This will pull SEA FOAM down on top of the pistons and to the back of the intake valves to dissolve carbon. Turn ignition off. Restart engine after 5 minutes.

 

have someone rev it and they can also turn your car off real quick... your engine should be completely warm otherwise hydrolock has a much larger chance of occuring. feed it sips of seafoam and while someone is holding your rev at about 2,000rpm and keeping it there. don't pour enough so your motor stalls... you want to turn your motor off manually (may sputter out after you turn off the ignition, covering the vacuum line with your finger or reconnecting helps it die). for more info about seafoam do a search, there are a couple seafoam threads on TN.

 

if your gonna let the line suck it in, dont do it with the brake booster line, its too big, do it with a small one and not too fast or you might lock it up

 

This is crazy, think about it, you're risking an expensive engine on a $5 product with a convoluted application procedure.
Try AutoRX, you just dump it in with your oil change and change the oil in 1500 miles and your done. It'll dillute all of the engine crud safely. I haven't heard of any catastrophic events happened by it's users either. I've had it in my truck for a week and it already stopped the serious oil leak.

 

You can't suck Auto-RX into the intake manifold...
It has one use. Mixing with oil.
Seafoam mixes with nearly anything. Gas tank, sucked into the intake, oil, transmission fluid, power steering fluid.


Gotta pay attention and learn your products first PRG...

 

I got some seafome this morning after work.... decided it was time for another cleaning--- I did this about 50K ago when I got the car.... and to my surprise, just one little puff of smoke... less than half a second! with my 5sfe having 200K on it.... it made me feel a little better.
