The cylinder head is one of the many important parts of the engine in a BMW motorcycle. It's essentially a housing, usually made of cast-iron or aluminum and located atop the engine block. It contains other critical engine parts -- the intake and exhaust valves, the valve cover, the springs, and the lifters, to name a few. Perhaps most importantly, it's where you can find the combustion chamber.

What Does a Cylinder Head Do?

What cylinder heads do is pull air and fuel in via ports or tracts, expel exhaust gases, and help keep engines cooler by directing coolant into their blocks. They also help prevent water or oil from leaking into the combustion chambers using head gaskets.

How Can I Tell if the Cylinder Head on My BMW Bike Engine is Faulty?

Unfortunately, no cylinder head lasts forever -- one can go bad owing to several causes, but there are signs you can look for before that happens. They include:

Cracks
Oil leaks
Leaking coolant
Engine misfires and overheats
Other engine performance problems

See any, and you should do a thorough engine inspection, followed by a cylinder head replacement if necessary -- that is, if not a complete engine rebuild, depending on the results.
