    Your fault, not BMW's.
    On a well maintained m20, what exactly goes wrong? Please let me know so I can look out for any issues on a car I have had for over 80k.
    Kthanksbye.

    ^true. Bought mine over 4yrs ago. 2nd E30. Over 250k similar to yours. Do maintenance on it as well. It feels like it has no end in site and leaks no fluids or burns anything.
    I am in the process of swapping to something with a little more umph but not because of the M20. It will probably go into the wifes E30 since we just bought it and I am unsure of it's history.

      they got the idea because belts are more efficient. they ditched it because soccer moms want to drive their cars into the ground.

      I wouldn't use the M42 timing chain as an example of a robust, highly reliable engine - most M42's are ticking time bombs. it costs more money to rebuild than it's worth, by far. I really wanted to buy my friends 318is, it was a fun car, but that damn motor..

          As for timing Chain vs Belt, Chains are more common in racing engines due to their strength and reliability and accuracy. Yes I mean accuracy because in a race engine the chain is replaced often enough that chain stretch is not a problem.

          Where belts are accurate for there whole life time, and are quiet, that is why they are common in most standard engines. The only reason why they are not used so much in racing engines is purely because they can break, with constant on and off of the accelerator and race springs and cams the chance of failure is much greater, and when you are racing a $50,000 engine a belt snap is not what you want.

            Agreed.

                For its time m20s were very well constructed engines. Even with high miles these engines keep running strong. They may leak every which way and even ways youve never seen before but besides that ive enjoyed mine. Ive owned the car for a year and not one mechanical breakdown yet. M50s hit the shitter(supposedly) around 200k, mine has close to 300k and is till daily driven and runs like a champ. They may not be well on the performance aspect but they do their job well, and just as well as any bmw engiine every created.
