The brake booster is about the best place to go. Most vaccuum tubes come directly off of the manifold and anything that gets sucked into it will make its way into every cylinder. Every time a valve opens on one of the cylinders and the piston goes down, its sucking in anything that is in that manifold. I think that the only time this would not apply is if you have a split engine that has 2 carburators or something like that.

I hear you on two bottles. My question was more along the lines of is it better to put it in more than one place to get the best results? I.E. a vacuum line and the spark plugs holes. Would like to know what has been the best technique for injecting into the M20 to yield maximum results.Comment

I remember when the old school guys first discovered Seafoam. There were a bunch of threads exactly like this one. That stuff just plain works.
I have had a can of it in my cabinet at work for a few months now and I keep forgetting about it, but after reading this thread, hopefully I'll remember. It's good stuff!sigpicComment

did you guys have to change your plugs afterwards? I just put in new ones and forgot to use my can of seafoam... don't really want to foul out a new set.Jay

I dunno, maybe it's just a placebo effect... I didn't notice any difference when I tried it last year, although it was cool to see a huge cloud of smoke going through my neighborhood :D. I think I scared some old Viet ladies walking by.
Still had lopey idle and whatnot. If you're looking for a cure in driveability issues, ur better off saving money for a tuneup. Buying a new distributor rotor helped a lot more than teh foam ever did. If you already have new parts then I guess you should try this.Last edited by brandondan1; 08-12-2007, 09:57 PM.

I would try this in my daily driver 325e, but I'm afraid Seafoam would be the straw that breaks the camel's back and that'd be the end of the 120,000 mile timing belt.

Seriously... change that belt. It only took me a few hours to do a FULL tuneup on my eta the other day and cost me 250 bucks. Should be good for the most part 50k miles.:: PNW Crew ::

i was reading this thread and it reminded me i needed to do it, so i went out and got some, put it in 1/3 of a bottle at a time and repeated the steps three times. i got black smoke all three times. i think im going to go get another bottle and do it some more. do i need to keep doing it until there is no more or considerably less black smoke or is 1 bottle good enough. btw my engine is in very good condition, runs smooth as hell, has lots of power, seems like it cant get any better but when i put this stuff in i noticed that it just seemed more healthy and quieter. cant really explain it but i think it helped.Comment
