E32 V12 - Seafoam

I'm helping a friend Seafoam his 750, I just need somebody to tell me where the vacuum tube is where I'm supposed to put some in. I had a 735 so I don't know where it is on this engine. A pic would be very helpful, thanks!



He thinks here...



On the intake tube

Vacuum line on FPR or in tank only

You're saying #12?



I know to do the fuel tank also, I was asking more for the other place to put it

That's the intake vacuum line. I used that line on my 540 (M60B40) but it went to the idler valve, aswell in my landcruiser (2uz-fe v8) it worked and it sucked all the seafoam and the engine ran reeeeally rough. Does that line lead to the idle valve?

I don't think that one worked, I haven't seen him since we talked about it. i think i need to pull up that plastic cover and run it into the one I talked about in post #3

Oh, okay yeah try that vacuum line. Some people have been saying put it into the brake booster but that doesn't sound right IMO.

yeah, I don't know what the brake booster would do for it... I need to clean out the fuel system because it's not burning correctly

Vacuum line # 12 WON'T work, and whoever told you to put it into the brake booster needs to be punched in the face for even opening their mouth. FIrst of all, you can't put it into the brake booster. Secondly, the brake booster runs off the hydraulic system which does NOT mix with the intake system of this car - the brakes are NOT vacuum assisted.

I am not really a fan of Seafoaming an all-aluminum engine anyway...

I agree, not planning on ever doing it to my M54 but on my buddys car we thought of it as a quick first option to get the car to pass smog. If not #12 then where do you think he should try it (besides fuel tank)?

Just a hunch, but if it's not passing smog now, it won't after using Seafoam either.
