First of all if you are unfortunate enough to have a cam belt snap on a JTDm diesel engine it is not as bad as you might expect, the engines dont USUALLY bend valves they snap the rockers in half. The 1.9, 2.0 and 2.4 are basically the same engine so this guide works for all of them, just remember that the gasket s are different. So here goes, remove the top engine cover
This will expose all the valve gear. Note the cam carrier gasket
Replace all broken rockers
Fit camshaft locking tools into their respective holes and then re assemble the engine using the reverse of the procedure above using a replacement cam belt kit and while you have this part of the engine stripped consider replacing the water pump and injector seals. Make sure you time up the camshafts correctly using the respective related link below.
