Sorry to hear that Denviks!

Popped the cambelt on my 200 and all it did was bend 4 push rods, so fingers crossed and good luck.

OHC on yours mate. IIRC you'll be looking at vlaces and rockers. I dont think they eat the pistons though.

Over Head Cam

On the LR engines (200 and probobly 300)Tdi the camshaft is in the block. Pushrods ride against the camshaft lobes and these go up the side of the engine. As the rod goes up, it pushes its side of the rocker up withc rocks (unsurprisingly) and pushes the valve down. When the belt breaks and a valve sticks down, most of the time the impact of the piston hitting the valve is transferred to the long bendy pushrood, which bends. Sometimes the valves do too.

In order to keep valvetrain weight down manufactueres went for overhead cams, less weight means faster, more agressive openings and less tendancy to overshoot. On SOHC (Single OverHead Cam) engines like yours, the camshaft is in the cylinder head and runs down the middle. The camshaft acts directly on the rockers which act on the valves without a long bendy bit of metal in between. The result when the piston slams into the cylinders is lots of kinetic force and no-where to go. The valves normally bend or one side of the rocker just snaps off. On a petrol engine with light alloy pistons you might be at risk of punching a hole in the piston too.

DOHC (Double Overhead Cam) engines have two camshafts in the head, in some cases these act directly on the valves. In this situation things get more expensive. Think bend/broken valves, holed pistons and in extremes, bust camshafts.
