This is a unique issue the E46 BMW M3 suffers from. I have repaired and installed reinforcement plates to at least 20 cars so you can rest assured the repair will be carried out efficiently and to the highest standard without costing the earth. I can supply the reinforcement plates or if you would prefer I can supply Redish Motorsport reinforcement plates. bmw in Edinburgh specialist
The head gasket on the legendary S54 E46 M3 engine is known to be a weak point. This is due to the very small spacing between the cylinders. However, as the engine is closed deck the issue can often go un noticed as there will be no common head gasket failure symptoms like water loss or over heating. If the issue is ignored it can cause permanent damage to the cylinder head.
Vanos problems are the achilleas heel of the older generation M3. The vanos system, when working correctly gives the straight six naturally aspirated engines that power these cars, incredible power and torque delivery throughout the rpm range. When the vanos systems starts to fail or develop problems the engine will be losing power. If you have any vanos queries do not hesitate to call.
The E92 M3 S65 V8 engine is fantastic. A high revving light weight V8, what's not to love! However, sadly it is known for issues with the rod / big end bearings failing. The issue is well documented, and the consensus is that the oem bearing clearance is too tight, leading to premature bearing failure. This is a bitter pill to swallow as replacing the bearings is not a cheap solution when there doesn't seem to be any sign of a problem but, it is a lot cheaper than replacing the engine which is unfortunately the usual outcome should the bearings fail. I have also replaced many sets of E46 M3 S54 bearings. If you have any questions or concerns regarding this issue, please get in touch.
