Don't be tempted! If your engine has a broken timing belt, a flat cam, or a cracked head. . . don't be tempted into replacing or rebuilding your head unless it has less than 100,000 miles on it. This can create big problems in a very short time. Installing a rebuilt or new head on an older engine can result in blowing up the bottom end of the engine. This is caused by the increased cylinder pressure from the tight sealing valves of the new head. The old bottom end cannot compete with the increased pressure created by the new head and will soon start to burn oil and lose compression resulting in the need to replace the entire engine. So don't take chances--if your engine has over 100,000 miles, opt for a complete engine replacement. Its not worth the risk. However, if your vehicle has less than 100,000 miles on it, Bavarian also carries a complete line of quality rebuilt cylinder heads for most BMW models.
