BMW S54: Everything You Need To Know - The BMW E46 M3 Engine Guide

►Getting into an S54-powered M car, whether a BMW E46 M3, a Z3M, or a Z4M is a memorable experience. The inline-six engine has been a staple in BMWs since its introduction, and few have garnered more respect and admiration than the S54B32 found in the E46 M. The high-strung, naturally aspirated mill screams motorsports pedigree at rest and shrieks its way to a 7900 rpm red line with a sound bested by few engines, regardless of cylinder count. Over twenty years since its introduction, the S54 remains a highly-capable performer on the street and on the race track, thanks to its strong output per liter and deep aftermarket support.

In this BMW S54 diagnostic guide, you will learn about the common issues such as VANOS failures, connecting rod bearings, camshaft sprocket bolts, timing chain guides, oil leaks, water pump, and the always necessary valve adjustment. If you're looking to modify your S54, this guide covers that as well, both for performance and for reliability.
