I put seafoam through my gas tank, but now I want to know how I could apply through the pvc tube? I bet not too many have done this...will i benefit from it? I've got 55K on my car now.

I've used Seafoam Deep Creep on my 70' Torino engine bay, makes everything look great, cleans the grease and oil right off. Ran some through the carb and in a few min. spewed black smoke for a few revs then cleared up... guess I burned the cobb webs out.
The Deep Creep is the same thing as regular Seafoam only in an aerosol, that may solve your problem.

I've never seen the heads off a 4.0 sohc at that low of mileage. We have about the same mileage you have (53k at last oil change).

I've used Seafoam on our high mileage vehicles (Our Explorer is over 350k miles).. That engine had all kinds of carbon build up and sea foam seemed to help. I've seen the top of 150k engines (sohc) and they actually weren't that bad..

People on the explorer board like to put it through the brake booster hose on their 4.0 (ohv and sohc). The 4.0 on the explorer is basically the 4.0 mustang engine.

I was planning to run seafoam through it around 75k miles (that will make it about 2 years of us owning it)..

I've placed it thru the break booster on a Mercury Cougar, Nissan Pickup, and a Nissan Altima. The Nissan's were a pain, cause they wanted to die everytime they breathed air from the outside so you may need a second person to up the idle some. You are looking for a vacuum line that goes straight to the fuel injection. The pcv line should also work. You'll know it's getting to the right place b/c you will smoke up the entire neighborhood. I usually kill it and let it sit for a few hours to eat away anything else, the run it wot on the interstate.


By the way, I ma not a mechanic, so don't cry to me if you break something
