The SL11626 P030 valve guide is a PMA aircraft engine cylinder head component used in Continental-compatible piston engines. It provides a precision bore that supports and guides the valve stem (intake or exhaust depending on installation), ensuring correct valve alignment and controlled movement during engine operation.

The P030 designation indicates an oversize +0.030 inch repair/oversize fit, used when the cylinder head has been machined to accept a larger guide during overhaul or repair.

Key features include:

PMA replacement valve guide
Oversize specification: +0.030” (P030)
Precision-machined alloy/bronze material (application dependent)
Maintains valve stem alignment in cylinder head
Ensures controlled valve motion and sealing performance
Designed for high-temperature exhaust and intake environments
Oil-lubricated interface with valve stem
Compatible with Continental piston engine cylinder heads (model-dependent IPC use)
Used in cylinder head overhaul and valve train rebuilds
Aviation-grade wear component for certified engine maintenance
