Seafoam- Y34 M45

[DRIPS]

Any of you seafoamed your m45 through any of the vacuum tubes? Most have probably dumped the can into your gas tank, but im looking for more of a deep cleaning...

[THT]

Seafoam doesn't have the cleaning properties of a product such as Regane Gumout which contains the necessary cleaning esters. If you want to use additives, go to Walmart (seriously!) and pick up a bottle.

[DRIPS]

But what about going through the vacuum hoses? how do I do that? is it recommended?

[THT]

You can. The way I've done it in the past is:

1. Pour some into a cup2. Start the car3. Disconnect the brake booster vacuum line (may need someone in the driver's seat, playing with the throttle to keep the engine running)4. Allow the brake booster vacuum line to suck up some of the Seafoam...don't submerge it completely...have it suck off a little bit at a time.

this will not harm the car right?

im trying to do the same thing, does anyone know what the brake booster line looks like or whats it near?? a picture would be great lol?? thanks

Seafoam? The same brand that makes the penetrating oil? I have to admit they do good at breaking bolts loose, but if you want to keep your engine pristine, use Chevron's engine cleaners that contain Techron. This is a gas tank additive and works very well. It will clean the valves extremely well if used in every 3rd or 4th tankful. The only time I ever heard of cleaning an engine by ingesting it into the intake was about 30 years ago when we used to pour a pint of transmission fluid in a warm engine. You have to do this at night or have very understanding neighbors..:-)

Correct. But the easier and more effective additive is one that contains esters such as Gumout Regane.

Hit up the BG website use BG44k and you will get the same results more of less, with a known product, Bg also provides a throttle body cleanser which is where most of the cleaning is needed due to the volume of air being passed through it, i have used BG products all the time and they are great. Here is a thread i made a long time ago and the fuel injection system cleaner could be poured into a cup and have it sucked through your brake booster vacuum line to clean out all the yucky things. Enjoy and search and you will find tons of info on bg products.zer...97944

BG44k I agree! That seafoam may trigger some sensor and have your dash panel looking like a christmas tree... and off to the dealer you go. $$$ I seafoamed my 1980 Datsun 510 and noticed little to no results, plus my up-scale neighbors looked at me like I was crazy as the car smoked up the street for 20 minutes.

ok. so bg44. where is the brake booster line?

[gammer_ghn]

by your brake booster big black round thing that has hoses coming off of it just trace the one to your plenum and pull it and use the injector cleaner can to clean out the crap but your car will be smoking so dont worry it wont harm your car... If you want to spend $100 your dealer will do it or if you can go strait to your dealers underground mechanic shop do it there for $40 so you wont mess things up just in case and learn as the mechanic does it!

Here is a shot of the brake booster line that I found thanks to all of your help. I thought the pic would help others. It is a Y34 generation. The tube came off with just one hose clamp. With the engine running there is a noticable suction from this tube once removed from brake booster. It slurped up the seafoam nice and easy.

Agreed, good stuff.

Just a tip to all. i'm not sure if the BG product comes with a drip kit or not. This is my cheap way to inject the product into the brake boosters vacuum line: Go to Walmart and get one of those tubes (clear) that has a tappered tip (yellow) at one end and an adjustable valve/ 1qt bottle oil female threads at the other (blue). I don't really know how to describe it all that well. The thing is one piece and is about 12" long. It's about $4 or $5 dollars. Somewhere close to it should be a clear bottle that screws into it ($3.00). At home, cut the bottom off of the clear bottle. Screw the bottle into the tube. You can even drill a small hole into the top of the bottle near the section you cut off to place a hook or wire through it to hold it up by hood somewhere high. Then insert the tappered tip into the end of the vacuum hose where you disconnected it at the brake booster. Make sure the adjtustable valve is closed where the bottle screws into the top of the tube. Start your vehicle and place a light object (something that is like a stick or cut down broom handle). Place it between the seat front and the gas pedal. (Make sure to place something between the object and the seat to protect the seat from damage)Note: Make sure your car is in park and parking brake is on!Then using the power adjustable seat control, adjust it towards the gas pedal until you achieve 1500 rpms. (Do not exceed this rpm)Then pour your cleaner of choice into the cut off bottle. Then adjust the valve to get a very small stream going through plastic tube. (Do not allow it to rush through the tube! This will and can stall the engine, foul a spark plug, or set off sensors!) Basically it should trickle slow enough to where it would take 15-20min to use up your product in the bottle.Note: The vacuum suction will collapse the tube. However it will still flow through it.

This is the cheapest way to perform this the right way. Doing this procedure too fast will cause more problems than good. If you do this the proper way as I described you will elliminate:-Triggering sensors-fouling spark plugs-Stalling the engine-excessive smoke from tail pipes

You can also purchase a professional style drip line (looks like a medical IV type system) I forget where you get them at, but they cost between $60-$100)My way will net the same results for a quality done job at a low cost.Let me know if you have any questions about any of this.

Good point. I forgot to mention I only did 1/3 of a bottle and slowly injested it. I did the`1/3 of a bottle over about 4 minute period.
