Valve Guide A precision sleeve pressed into the cylinder head that supports and locates the inlet valve stem, holding the valve concentric with its seat throughout the lift cycle.

The guide maintains accurate valve alignment, conducts heat away from the valve stem into the cylinder head casting, and meters the lubricating oil that travels down the stem. It serves the inlet valve position in the four-cylinder petrol cylinder head.

Worn guides allow the valve stem to move laterally, leading to increased oil consumption, poor valve sealing and accelerated seat wear. Renewal restores the correct stem-to-guide clearance and proper valve seating.

Frequently asked questions

What does the inlet valve guide do?

The inlet valve guide is a precision sleeve pressed into the cylinder head that supports the inlet valve stem and holds the valve concentric with its seat throughout the lift cycle. It keeps the valve aligned, conducts heat from the stem into the head, and meters oil down the stem. This OEM AE guide suits the 2.25 petrol head.

How do I know if the valve guides are worn?

Worn inlet valve guides typically let the valve stem move sideways, causing increased oil consumption, blue smoke, poor valve sealing and accelerated seat wear. Renewing the guide restores the correct stem-to-guide clearance and proper seating. New guides usually need reaming to size after fitting.

Is this the inlet or exhaust valve guide, and which engine?

This is the inlet valve guide for the 2.25 petrol four-cylinder engine, fitting the Series 3 and Defender (1986-2006). It's a different part from the exhaust guide, so check whether you need inlet or exhaust guides before ordering. Fitting valve guides is a specialist cylinder head job.
