friend was asking as the timing belt broke in her van..
theres actually two timing belts on the 2.4; the injection pump is driven off the back end of the cam (right hand side of the engine near the gearbox), and the 'engine timing belt' or main belt on the left hand side of the engine, as you look at it, with the bonnet open...
...It might be worth investigating which belt is gone; not unknown for the pump belt to break, as it often gets neglected or overlooked on timing belt replacement intervals...
...if its the 'engine timing belt' as 56oval says it might be worth whipping its head off, n checking 'valve to piston interface' damage... theres actually decent access to the engine when its in there, with the front panel/rad carrier unbolted n slid forward/taken off...
...sounds like its worth fixing if its a caravelle with a pop top; it can be hard to buy a decent t4 (as a replacement) theres often a huge gulf between shagged out n tired examples n clean well cared for oone, n the price often doesn't reflect these ie the tired ones can be 'overpriced' for what they are...
