6x Valve Guides for PORSCHE 356 911 F/G SC 930 964 3.3 1. OVERsize 93010432150 1. Oversize Description: As part of an engine overhaul, the valve guides should also be replaced. Worn valve guides cause the valve stem seals to wear excessively quickly and leak again soon. Furthermore, with new guides, the valves seal reliably again, restoring the best possible compression to the engine. Please note that on some models, these guides only fit the intake side. This is the so-called 1. Oversize. This item is also available in the standard size.
