Yes, if the cambelt on a Corsa Utility fails or cuts, it can lead to bent valves. This is because the engine's pistons may collide with the open valves when the belt breaks, particularly in interference engines where the piston and valve paths occupy the same space. It's essential to replace the cambelt at recommended intervals to prevent such damage.
Yes, I have Just had the timing belt snap on mine and some of the valves were bent by the pistons.
bent valves and/or holes in pistons.
As its a diesel if the cambelt has snapped i would say the head is going to have to come of and you will be needing some new valves as they would of defo bent
If a cambelt broke while the car was running, it is likely that there is damage done to at least one valve and the head. This engine comes from the Ecotec line of GM engines, which are all interference engines. The term "interference engine" means that if the timing is not exactly correct, the pistons will run into the valves and essentially destroy the top end of the engine. Depending on the year and model of your engine, it may have an aluminum head. If it does and the valve sustained damage, there will almost certainly be substantial damage to the head and it will need to be machined or replaced along with the valve and possibly the piston and ring from the cylinder that damaged the valve.
no it is fully and completely interference, cambelt snap will mean engine rebuild, lots of bent and broken valves and so forth
The 800cc engines are NOT non interference engines. I recently bought a matiz with a snapped cambelt. After reading online that it was a safe engine I simply reset the timing and fitted a new cambelt. The car seemed to run fine so I thought I was in the clear. 12 miles later one of the valves snapped and killed the engine, lots! I stripped the engine down after I'd removed it from the car and found that 5 out of 6 valves were bent.
Bent valvesBent valves
One of the most common reasons for bent valves is a broken timing chain or belt.
severe engine damage, bent valves popped, valve seats, scored piston heads from ring seals breaking up & so on & so on
The main cause for bent valves is a failure in the timing chain or belt. When the valves and pistons are not exactly in sync, they can collide.
If the valves bent, then yes.
You can do a cylinder leakage test to check for bent valves.You can do a cylinder leakage test to check for bent valves.
