WHY ARE THEY SO IMPORTANT?Specialty repairs are not offered at your average repair shop because most repairs of this nature require factory training, specific tools, extensive experience and a unique knowledge to execute them properly. Excelerate Performance has brought all of these requirements together into one shop so that your specialty repair doesn't become especially disastrous.
S54 VALVE ADJUSTMENTThe S54 has been known to be very reliable sub breed of BMW’s lower output M54 engine but requires maintenance to last like any other engine however, more frequent maintenance is required for the engine’s longevity. The M3 e46, Z3M, Z4M with the S54 engines all use mechanical valve lifters which have a higher RPM capability despite their ongoing adjustment requirements. So, why is a valve adjustment so important? Without proper valve clearance the valves will not seat fully. A partially open valve will result in compression loss and improper valve cooling. The final result is burnt valves. When this happens you must remove the head and send it to a machine shop for a valve job. This is a far more complicated repair process than can be avoided by a little maintenance. This now extended repair will now lead you to having to replace unnecessary parts that are not typically known to not be a problem. When letting these maintenance items go too long without being addressed you usually find yourself fixing things that never needed to be replaced in the first place.
What is a valve clearance and why is it important to adjust valve lash or clearance? Valve clearance is the space between the rocker arm and the camshaft. Why important? If you have too much or too little clearance it can quickly cause extreme damage to your engine. But before the catastrophe comes reduced performance, a noisy valve train, poor gas mileage, excessive emissions, etc. But in order to adjust valves properly you need some special tools, measurements and knowledge. Excelerate Performance’s service team has it all. Contact us to find if you need to have your valves adjusted!
