🔌 Function

The camshaft rotates in time with the crankshaft and its machined lobes actuate the valve gear to open and close the intake and exhaust valves at the correct points in the engine cycle. On these engines it also drives associated timed components of the valve and injection train.

⚠️ Common Signs of Failure

• Worn, pitted or scuffed cam lobes causing reduced valve lift and loss of power
• Excessive valve train noise, ticking or tapping from the cylinder head
• Scored or worn journals leading to low oil pressure and bearing damage
• Rough running, misfire or poor starting from incorrect valve timing
• Metal debris or bearing material found in the engine oil or filter

🛠️ Service Notes

• Oil the journals and lobes before fitting and lower the shaft in squarely, without dragging it across the bearings or bearing bores
• Inspect the parts that run with it as a set — followers or rockers, bearings and the drive gear — and renew anything worn; a new camshaft on worn followers will not last
• Line up the gear timing marks and check valve timing before turning the engine over, and never force it against resistance
• Tighten bearing caps and drive gear fixings in the sequence and to the figures in the workshop manual for your engine
• Prime the oil system and turn the engine through by hand for a full cycle before starting, then keep the first period of running gentle
