Block and cylinder head work

Block honing addresses the final cylinder bore geometry and surface condition when appropriate. Resurfacing addresses a sealing surface within its repair limits. A valve job concerns valve and seat sealing; it serves a different purpose from resurfacing. Inspection determines which services belong in your project.

Crankshaft and bearing-related work

Crankshaft journals need evaluation for size, geometry, damage, and finish. Grinding and polishing remove different amounts of material and are not interchangeable. Discuss the correct repair and matching bearings before ordering components.

Bring the right information

Share engine identification, symptoms, prior machining, and intended use. If the engine is already apart, ask which components to bring. Clarify whether your estimate covers component machining or a larger rebuild and assembly project.
