bravo 34 Report post Posted November 25, 2005 Tappet noise could also be a worn cam. The noise may also be injectors not tappets. I haven't done it in a bimmer, but i replaced the tappets/lifters in my VK and they were $11ea from the dealer, but then you have to remove the head, have it polished, replace gaskets etc, and so on - cost only a few hundred in the end, but was way more than the 100-200 I had budgeted as an inexperienced 17yo at the time. But if they are replaceable on the bimmer in a similar fashion, might be better to do that . But the again could be cam or injectors as said. I wouldn't bother doing it as a special job.

Madhatter 0 Report post Posted November 26, 2005 they dont have tappets, they have eccentrics. If you set it and it still ticks you probably have worn eccentrics or you need to work on your technique a little. Quote Share this post Link to post Share on other sites
petone 0 Report post Posted November 26, 2005 Tims right, they all tick. If they aren't ticking you probably have them set too tight, which isn't good. When I do mine its alot quieter and smoother but still ticks. Quote Share this post Link to post Share on other sites
Madhatter 0 Report post Posted November 28, 2005 (edited) they dont all tick at all, not when everything is fine. They should be fairly quiet, if anything injectors make more noise. Eccentrics are known to wear, thats the point of having them, if it continues ticking its usually down to worn eccentrics.

I think what people are trying to get across - with the worn eccentrics (which nearly all m20s will have by now) you will always hear tappets even with the correct adjustment.

Guest Spargo Report post Posted November 28, 2005 case in point - mine is a 270K 2.7 with perfectly adj tappets = noisy as sh*t. Quote Share this post Link to post Share on other sites
