Peugeot 307 1.6 16v Automatic: Timing Belt Failure at High Speed - Possible Valve Damage?

Hello. After replacing the timing (the whole set plus a water pump) after about 250 km, the belt burned through the housing, rubbed and then broke, everything took place on the highway at about 100 km / h 3 thousand revolutions ... that I found out about the belt only after I opened the engine hatch. Why do I mention it because after it broke or rubbed, of course, I had no power under the gas pedal, but the engine worked nicely, the revs dropped slowly and the automatic gear reduction gear ... is there a chance that the valves were not grayed? Will it be possible to start it after replacing the belt? Please help

collision and high costs here. After removing the head, it will be possible to estimate the damage and costs

When the belt breaks, one shot is taken and the engine stops.
Since you turned off the engine yourself, there is a good chance that the losses will not be large.

at about 100km / h 3,000 revolutions.
the machine reduced gears and as you write that the belt broke at 3,000, it's not good. I think that the big problem will be to determine why it cracked and rubbed the housing - the tensioner wheel or the roller

Hello. It is difficult to answer this question unequivocally. Most likely there was damage inside the engine but ... If you don't check it, you won't find out. I suggest putting on a good timing belt for a test, then rotate the engine shaft at least 4 times and check while turning whether you feel compression in the cylinders and whether the engine suddenly locks up at some point. If compression is noticeable resistance and the engine does not block up, test the firing and test drive if it works properly.
Of course, I will add that the cause of the failure should first be removed, which caused the belt to be damaged
And the belt is completely broken or is some part still encircled by the gears?

Is it 3,000 RPM or idle does not matter here, the mass of the crankshaft is enough to bend the valves. The noise from under the timing covers did not disturb you? You should go to what the timing assumed you.

"And the belt broke completely or some part of it is still around the gears"

Yes, I would even say he didn't break up. But these are scraps, not a strip ... After undressing, I'll find out more.

if it was about 3,000 revolutions, I bet at least 12 valves to be replaced and I don't know what about the guides

It's not possible, but it's just jumped a tooth or two and hasn't damaged the engine yet. Good luck and happiness
