All light weight, high output four cylinder engines  has some weaknesses which is inevitably showing a learning curve from their respective manufacturers.

The issue at hand is multiple fold, in one hand high output is a trend and a side effect of removing friction and removing mass from inside an internal combustion engine. Even tough many of the most well known manufacturers are building engines over a hundred years plus, worth to say no one is exempt from the occasional flop while they are working hard to try to squeeze the most out of this ever shrinking engines.

Here is one example, the BMW N20 4 cylinder engine which has a timing chain issue at hand. Naturally the engine is in typical BMW fashion very innovative except it  is prone to timing chain issues which is related to variable oil pressure.

The problem cause by  the ECO mode on the automatic transmission, which consequently lowers the engine rpm allowing higher crankshaft oscillations at low engine rpm.

We have performed myriad of chain replacements, naturally with the newer genuine revised components. Timing chain replacement on a  BMW N20 4 cylinder engine is a major repair due to the complexity of the proper procedure which must be followed.
