Keeping your E30 in good running order doesn’t have to be costly. If you’re a BMW enthusiast, chances are you’re also a DIY enthusiast. Let’s be honest, not many people can afford to run to their indie mechanic every time they need a repair on a car that’s over twenty years old. For example, something as simple as a clutch slave cylinder replacement can cost nearly $400 with parts, labor and tax at a local garage. This is something the weekend mechanic can repair in a few hours with around $60 in parts.
Learning how to correctly adjust the valves on your M20 engine is an essential part of E30 ownership. Howling sewing machine sounds are to the E30 as air cooled flat six sounds are to the Porsche 911. Just how much sewing machine you get is up to you and your valve adjusting skills.
