Has anyone sea-foamed their 335?

235Dude · 10-27-2010, 02:57 PM

I want to give this a try since I'm just over 50K miles. I read the big thread on it and am kinda scared to do it on my own. Has anyonedone this on their 335? Is an oil change right after really necessary (I just changed it like 100 miles ago at the dealer)...

I seafoamed my car at the beginning of the summer and did an oil change 50 miles after. my thought was, better safe than sorry, especially on the n54's.

Pretty easy to do. you just gotta be careful when you unplug the vaccuum line. you also need someone to keep the revs up while the seafoam is sucked into the vaccuum line.

I would also definitely change the oil afterwards, so if you recently changed your oil, I'd just wait until the next oil change.
