Sea foam Question

[Jimbo88]

I have been reading around on the sea foam and i just want to double check that i am going to be doing this right. I would take out the PCV valve and pour into there slowly using a funnel while the X is running right. I didnt want to screw anything up so i thought i would check. Thanks

Take the vacume line off the brake booster...that's what I did, and have someone there to work the throttle to keep you from killing it .

Good luck

OK this is a really dumb question but which one is the vacume line?? I thought it was the line that is on a black box with two removealbe knobs and two line hooked up on top. Is it the one running to the eninge??

As you stand in front of your truck, look toward the back of the engine bay on the driver's side. There is a round black thing attached to the firewall. Out of this round thing is a black hose that runs about 1 foot toward the engine. This is the hose you use to suck in the Sea Foam. It is attached to the top of the engine along with some other vac hoses. It should be fairly easy to un-attach.

A lot easier than the PCV.

And by the way, you don't need a helper to gun the engine...you can do it yourself if you pull on the throttle body butterfly..

Thanks! i will try that

If you use the brake booster vacuum hose, the seafoam is really only getting into the rear-most cylinders. If you use the vacuum line that is on the Throttle Body, you don't have that problem.

What I did was remove the vacuum hose that runs from the intake manifold to the PCV, tape a funnel to it, and pour. Made it really easy to pour with no mess at all.

I didn't know about the vacuum line body thing. Gotta try that one.

When I pulled the line from the brake booster, the grommet crapped out. It was old and brittle and crumbled. I drove for a day with it half leaking. Brakes felt weird and could hear it hissing. Alas, a special order part from my local dealer.

I just visited the dealer today for this very part but didn't want to pay $10 and wait a day. Drove up the street to a local parts store and they had a package of two sizes for 4.79. The smaller one worked great tho its inside diameter was a smaller than the original; stretched fine!

I guess we're lucky bums! My dealer was able to get it the next day and charged about $3. Too much for the little piece of rubber, but oh well.

Hey good point. I may try that next time..

Can someone post a pic of the better vacuum line to use? I'm an X newbie... I've got experience on imports, but this truck is new to me...

Thanks,

I don't have a PIC right now, but as you look at the throttle body, the vacuum line points DOWN (on a OHV engine atleast), if I remember correctly, it's the ONLY vacuum line connector on the TB. I am not familiar with the SOHC, or 5.0 engines, so if you have one of those. I can't tell you.

Just look for a vacuum hose to temporarily disconnect and suck in the SeaFoam. You want a vacuum line that is near the front of the engine. and NOT the Brake assist line.

this isnt explorer related... but if i run seafoam through my brake booster line... will it get to all my cylinders? i have an inline 4 cylinder? or should i dump it directly down my carb neck?

 

[Spdrcer34]

Maybe, JUST maybe the front cylinder will get some SF in there, but I doubt it. With way the airflow is flowing, any suspended liquid that is introduced at the REAR of the engine will be drawn to the REAR MOST CYLINDERS. It's simple physics. Pour it down the carb, or hook up a vacuum line on the carb to suck it out of the bottle.
