Yet another seafoam question

[GSpan]

I have a '98 Mountaineer. Never did a seafoam treatment before so I read and searched on the right way to do it on a 5.0. From what I read, there is no right or wrong way, So I decided to go directly into the TB. What I did was remove the tube that goes from the neck of the oil filler to the air in take tube, and using a funnel I slowly poured the seafoam into the air in take tube with the engine running. Doing it this way I figured between the air flow, and the fact that the tube is tilted back twards the TB, and its only about 2" away from the point I was inserting , it should all flow into the TB. While pouring the Seafoam in, I got no smoke. After pouring in about 1/2 the can, I dumped a lot in at once and stalled the engine. I waited about 1/2 hr. and started the engine. It took about 4 trys to get it to start and idle and got a ton of smoke. Drove it around for a while and the smoke cleared in about 2 miles. I noticed a difference right away.
My question is, by doing it this way, am I reaching all points in the intake manifold, or am I waisting my time and money? I figured the airflow has to go through the intake manifold, and it would take the seafoam with it.

I wouldn't think it would "suck it in" very well, but maybe. It's suck a large opening, I would think a lot of it would sit down in the intake tube, at least until you were running on the road and got more airflow. Most agree that sucking it on through the tube that connects to the PCV valve is the best way. It splits off and goes to the front and rear PCV hose. But if it runs better, then it runs better.

I was considering the pcv tube, but being the pcv valve is a royal pain to get to, (once again Ford desided not to go maintainance friendly in thier design) and the fact the engine must be hot, I desided not to go that way and avoid burning and scraping up my hands.

Good choice, but since my job for that day WAS to replace the PCV, I did it while I was in there. However, you can FIND it while it is cool, and then just yank it off while it's hot (heck, yank it off before it gets hot).
