Any Peugeot experts in the house ?
Ive bought a cheap 406 as a do-er-upa
1997 1.8 16v petrol xu
Cambelt has snaped.
I have started to strip the engine, I can move the exhaust cam with the tip of my finger. About 5 deg  so I am guessing thats eight bent valves to
start with....
Any body know what bits cost for these things ? I have had a google and cant find much, same with fleabay.
Any tips and pointers on the job in hand would be greatfull recieved.
Its my first pug engine rebuild 
cheers

I guess it depends whether it is a so-called 'safe' engine or not. Is the cam shaft just moving because all of the exhaust valves are
shut? or would that be wishful thinking. It might be worth trying to turn the engine over slowly via the crankshaft bolt to see if it gets stuck
anywhere.

Yes Crank has got to be in the correct position before you lift the head otherwise to turn the the crank more than a few degrees you have to clamp the
top of the liner to stop them coming up with the pistons.
Way to check for bent valves is get the head on the bench with cams removed turn it on its side pour kerosene into the ports -- bent valves will be
pretty obvious.
After replacing the obviously bent valves do the same again but direct an air line jet on the combustion chamber side of each valve working round the
curcumfrence, any valves that aren't quite sealing will show up as bubbles in the port. Usually you can get away with just lapping these
valves in.

Verdict is six very bent valves
And four suspect ones
Plus a small piece chiped out of the head
The pistons look ok
verdict, its going to be cheaper to source a fresh motor.
