    Cleaning Inside Engine

    Im planning on getting a e30 soon and since these cars are pretty old and most of the ones you find have been sitting for a while I was wondering whats a good way to nicely clean the inside of the engine of all build up, not only engine but just give the engine and parts a nice clean to get the most out of my engine.
    I looked up a lot of options and looked at what others have done and I see that seafoam work very well. I was planning on doing seafoam but as I read more I also got negative responses saying that it can cause problems in the engine like eating away at gaskets and such. Most of the people with these problems apparently were using to much or doing it wrong.
    I just want to make sure if this is actually a very good way to clean the inside of the engine and that if I do this correctly will I see any big problems?
    On top of that, any other options that are reliable, and safe, to clean the inside of the engine that worked for you guys would be nice to know.

    Thank you

    without disassembly? people use seafoam, i have no experience with it.

    in my opinion, all those additives and cleaners in a bottle that you dump into the engine are gimmicks. there's nothing as good as a rebuild but I can understand for many it's not within their abilities and/or budgets.

      Engines get deposits inside them, it's just what happens.

      Honestly, the best thing to do is change your oil frequently,
      change the coolant every coupla years, and the brake
      fluid at least as often.

      And drive it until it gets nice and warm every time.

      But otherwise, don't poke at it.

          Lol no, unfortunately self-cleaning engines aren't a thing... yet.

          Most of the top end cleaners are pretty much the same, the issue is how the detergent is applied. When I worked at a shop we had this air-powered canister that had a sprayer on it. Made the detergent into a super fine mist, did an incredible job of getting carbon deposits off of the inside of intakes (BG guy used a scope to show us the before and after, pretty incredible really. super goddamn corrosive stuff)

          Problem with most over the counter stuff is that they want you to hook the detergent up to a vacuum line or something. Doesn't do anywhere near as good a job of atomizing the detergent and typically makes cars run like ass. Also, if you pick up too much liquid, you can hydrolock your shit and then you'll be having a bad time.

          Besides, the most you'd pick up out of all that would maybe be 5-6 whores power. Zero increased reliability. Maybe a lot less emissions, but if you cared about baby seals and all that you'd be driving a prius, not an old ass dirty-running bmw.

              I just throw sea foam in my car once a year and call it good. SOME TIMES INJECTOR CLEANER THAT SHIT IS CHEAP.
              I had my head off the M3 and mechanic said it was one of the cleanest inside he has seen, minor to no deposits on pistons.
              Plus change oil every 3k

                This worked really well on my M50:

                Noticeable difference in smoothness.

                      we use BG products at the shop I work at and they do really work. the BG fuel induction clean cured my spark - knock on my e30

                        I'll hand it to them for the fuel injection stuff, but MOA? Snake oil IMO.
