Valve Guides

Valve guide dimensions: OD, bore and length

How to search without an OE number

Enter one or more measured dimensions in millimetres: outer diameter (OD), bore (ID) and length. Use the dimension filter to narrow the references, then compare the complete engine model, part markings, grooves, flange and end geometry. The search tolerance controls candidate matching; it is not an installation tolerance.

Same length does not identify the same guide

Check all dimensions rather than ordering from length alone. Record whether measurements came from a new sample, an installed component or a removed worn guide. Keep drawing nominal values and actual measurements separate; material, finished bore and machining allowances need project confirmation.

Prepare a valve guide or seat insert RFQ

List each reference, required quantity, complete engine model, intake or exhaust position, drawing revision, material and inspection requirements, packing and destination. Mark unknown fields for review. FarDrive coordinates authorized sales, specification questions, supplier quotations and technical or after-sales follow-up; availability and commercial terms are confirmed for the order.
