So Seafoam can be sprayed into the PCV hose, added to the gas, and added to the oil.

It seems like the best results can be seen by spraying in the PCV hose.

Is it safe or recommended to do all 3?

I was thinking of doing a 1/2 tank of gas and adding it to the oil and then once the gas is almost empty, doing the intake method.

Any comments/suggestions?

 

I would only do the PVC and gas treatments. I did the PVC treatment last weekend. Dumping seafoam into the oil is diluting and breaking down the oil. The only time you should do this is right before an oil change. Pour it intonthe crankcase and run the car for about 5 minutes, then drain the oil.
Running seafoam through the PVC hose really helped mine out.

 

Just did mine thru the PCV but from my understanding if you run it through the oil it is highly recommended that you do an oil change soon after. Some say right away some say within 500 miles.

 

Doing all three is fine but like mentioned before if you do the crankcase change the oil within 50 miles. Also does anyone have any pics of how to do it on an r53?

 

No pictures, but you don't need them. If you can get a second person to sit in the car to keep the idle up, it'll be easier.

1. Fire the car up
2. Keep the RPMs around 2000 (I used a 5 pound sledge on the accelerator because my wife was at work, but another person is safer)
3. Looking down at the engine bay, disconnect the PVC hose (left side of the front of the valve cover while looking down at the engine)
4. Either spray the seafoam into the hose or slowly pour the seafoam into the tube depending on which can you buy. The engine will start to bog down so stop until it comes back up to speed. Continue doing this until you have half a can in and shut down the engine.
5. Connect the hose and wait 15 to 30 minutes.
6. Fire the car back up and rev it up and watch your neighbors come running out with fire extinguishers. When the smoke calms down, you can take it for a drive.

Like I said, when standing in front of the car looking down at the engine, the PVC hose is on the front left of the valve cover. You can't miss it and there is no hose clamp on it. You just have to pull hard. There ate also other threads on here that have pictures too.

 

Ya I keep looking at it and just go derp!!!! Its so much easier on R56.

 

I got a can of the spray and a can of the liquid.

Does the pic in these instructions even apply to the MINI?

It seems everyone just sprays it in the tube, but there is this strange plastic 180 fitment on the spray tube.

I think it's better to use the spray in the PCV tube for the reasons listed in the instructions:

• The Sea Foam cleaner must be evenly distributed
• The Sea Foam cleaner must fully atomize

I'm an auto n00b, so which one of the sections in that link are more applicable?
Using Sea Foam Spray to Clean a Sealed Intake System
Cleaning the Induction System on Vortec and Other Exotic Intake Engines

 

You don't need the tube, just spray the seafoam from the nozzle on the can. That crazy tube is for different applications, like injecting directly into the throttle body, which is harder for us to do. Just hit it through the PVC and maybe run half a bottle through your gas tank.

 

Ya spraying it into the TB is about impossible on most new cars. You could probably do it on r56 if you disconnect the noise maker and slide the tube in through there. But I have looked hard enough at the Tritec to know where everything is to see it might even possible.

Looks a lot like Oxyblue's first video in this thread.
