Guía de válvula

This exhaust valve guide with a 0.2 mm oversize for the BMW Isetta engine (Part No. 1-0597) is designed for cylinder heads with heavily worn or rebuilt guide bores. It restores precise guidance of the exhaust valve and correct valve clearance, which is crucial for long-term engine function after restoration. Using a properly sized oversized guide can permanently resolve typical wear issues such as oil consumption and valve chattering.
