DIY Request: Seafoam

Nothing appears in search. If someone could snap a picture of the engine bay and highlight the vacuum hose used for a seafoam treatment I'd highly appreciate it.

Just follow the vac lines from the DV's to the intake manifold use that line to suck in the seafoam. The lines from the DV's should be two lines that conjoin with a Y splitter into one.

the top of the DV's are connected to a hose that join together... take off the single hose that they converge onto and feed it in through there...

this probably isn't a good enough explanation so just watch this video... pic at ~0:16. Mute your speakers unless you want to listen to mid-life crisis female music

Anyone want to hazard a guess on how we can do the seafoam on an N55?

I would say start by pulling off the plastic engine cover - and look for a vacuum line.

...we know there MUST be atleast one. After all the N55 still has that vacuum opperated exhaust flapper valve that the N54 has. Maybe follow that line back to the engine? I tried looking around the web for a foto... but I came up with ziltch.

Helps clean out the carbon buildup deposits on the valves and intake track

an old school way of breaking up and cleaning up carbon deposits (sludge). Since our cars are direct injection, it's not something that you can just add to your gas when you fill up, so instead you have to run it through the vacuum line. I'm not entirely convinced that it does much... but it doesn't seem to hurt anything.

^^THE really old school way is to use water in a cup! But done wrong and you'll end up with your con rods bent up like a pretzel! Some people also use ATF in the gas tank. But I don't really know IF that would work in a modern D.I. car.

Read my experience with carbon and see that seafoam treatment alone will not work on high mileage cars.

It's just steam cleaning the valves, nothing too serious, just have to be careful the amount being taken in, same as seafoam.

It doesn't say anything about seafoam in your posts. I'll bet we'll not know how well seafoam does work on these motors for a long time. Who is going to go through the trouble of taking their intake mani off and not clean the valves just to snap some pictures?

Very bad things happen when you add any additive to a BMW engine.

Yes, water really. Its an old trick. You introduce some water via a vacuum line. You do it when the engine is fully warmed up... the water vapor gets sucked thru the intake manifold... and the water droplets cool the hot carbon on the intake valves. This causes the carbon to crack off the valve. Do it long enough... and your'll remove a lot of carbon that gets built up.

Do it WRONG... by letting the engine GULP down the water... and well... we all know water does not compress like air... so you can end up bending a connecting rod.

I know a lot of subbie techs who do this on Subaru's flat four. Those engines are famous for carbon buildup! But... going in with dental scrapers or a gun cleaning kit is better and more thorough in removing MORE carbon builtup.

Personally I think the best way is to use Seafoam - spray it on the intake valves... let it soak a day or two... then go in there and scrape off the crud. Or... maybe that walnut shell media blaster that Harbor Freight sells. The walnut shells get impacted at the intake valve... what old walnut shells you miss to clean up... will get burned off in the exhuast anyways. I think that is a good option as well.

BG Products, seafoam, it's the same. In fact many consider BG to be better then seafoam.

And do a little research on e90 post.

http://www.e90post.com/forums/showthread.php?t=454069

"Valves and ports were covered with carbon.. not to the point where I'm too worried, but just enough to be bothersome. I wasn't able to get a clean picture. ** I had Seafoam'd it 3x 7,000 miles ago, 3x 3,000 miles ago."

now you know.

OP - here is what you are looking for:

Note, mr.5 ended up taking his mani off later and still found carbon build up after seafoam and running meth.
