How to Seafoam an Eighth Gen F150 (1987-1991)
#52
Okay, so i seafoamed mine today. I couldn't get it to die (AND I DUMPED ALOT IN, FAST!) then I let it sit, and just like you said, it smoked like a train. But the smoke was white. I would think it would be black if i were blowing out a bunch of carbon. I've been running gummout fuel system cleaner alot and it's suppose to clean out the carbon, maybe i just didn't have any. I don't know.
Anyway I looked all over mine and the best place it seemed to put it in was the driver side vacume hose for the PCV. It goes in right under the throttle body, i could'nt tell where the brake booster hose went to, it just hits a metal tube and disappears behind the engine.
Thanks for the info. Bye the way, how often should this be done?

James, mine didn't want to die either, but I suppose I got luckier than you and it died after a minute. All in all I wound up pouring a bit more than the original third of a can I recommended. Also my smoke was white as well. I don't know if smoke of a certain color means the 'cleaning' is more or less powerful. As for the technical procedure, I am not sure what the throttle body is exactly. However, is it possible you're doing this on a different gen F150? I haven't had my truck long enough to seafoam it more than once, however, I once heard that every 60k or so is good. Anyone else want to back this up or refute?

Did mine today
I know this a old post but sharring anyway. I seafoamed my 1992 F-150 302 today. Followed The instructions except I didn't put it in the crancase yet, Let it sit for 30 minutes. Only got a few seconds of white smoke not much at all really. But my throttle response was fantastic and my idle smoothed right out, Great product for sure. Thanks for all the detail. If anyone can respond. How often can I use this stuff in the gas and the vaccum. Thanks in Advance

I've read before with these older trucks putting it in the crank sometimes the clearing of the sludge causes clogged leaks to get freed and allows the leaks to leak. And also it sometimes blocks up the screen on the oil pump. Is all this true?

Trying this right now. My 1988 F-150 302 was running GREAT until I changed the oil and transmission filter. It is running like it was misfiring. It was sitting since 2007, so I changed the oil and filter, added Lucas oil stabilizer, also changed transmission fluid and filter, added Lucas transmission fluid, changed fuel filter, plugs, distributor cap and rotor..still had the issue. My next hit was fuel injectors.
Praying this works to increase my gas milage as right now I am getting about 10 miles per gallon.. This from 20 miles per gallon..
Thanks for the info an praying this works...
Would LOVE other input to this matter if anyone has had the the same issue..

96 4.0 explorer was one lifter was ticking real bad when cold, put a can and a half in the oil ran for two weeks, would tick when hot, changed oil and now it's purring. I gained 1.1 mpg before oil change, probably thinned oil out but it cleaned it.
