Why Replace This Part?
Worn or fatigued rocker arms can lead to improper valve lift or seating, reduced compression, misfires, elevated emissions, and may affect overall engine reliability. Upgrading to a high-quality OE-match rocker arm restores the integrity of the cam-to-valve train and helps maintain optimal engine performance and longevity.

SET OF 12 valve guides - standard. Inlet x 6 and exhaust x 6.

This is the standard valve guide used in early air-cooled Porsche 911/930 cylinder heads. It’s a plain (non-hydraulic) guide that locates the valve stem in the head; when worn it causes oil burning, loss of compression and poor valve seating — so they’re commonly replaced whenever heads are rebuilt.

What the part is (technical data / dimensions)

Application: Porsche 911 / 930 from about 1965–1989 (varies slightly by model and year; early cars both intake & exhaust, later years sometimes exhaust only). Standard size (typical OE): ID ≈ 9.00 mm, OD ≈ 13.06 mm, length ≈ 51.2 mm.

Why these guides should be replaced

Valve guides are a wearing item. Replace them when any of the following occur or when you rebuild the engine head.Excessive valve stem play — worn guide ID internal diameter lets the valve rock and misalign with the seat , poor sealing, reduced compression and power.Oil consumption / smoking — worn guides allow oil to wick down the stem into the combustion chamber, causing blue/grey smoke and fouled plugs.Hard starting, rough idle, misfire — poor sealing / valve timing irregularities from misaligned valves.Valve wobble that leads to premature valve stem wear or valve seat damage — once stems or seats are damaged you need deeper surgery.If a guide is cracked, broken, or has excessive ovality — must be replaced.Whenever you remove and refinish seats / replace springs / do a full head rebuild — replacing guides at that time is cheap insurance and ensures correct alignment.
