1300 Engine Problem- Advice needed!!!!

Hi all, I need some urgent advice regards to my 1300 which broke down recently.
Whilst driving at low speed and just about to change down a gear the engine died (estimated speed at the time was about 10mph). When the engine died there was a metallic/ tin sort of sound however this maybe normal for the fact I was changing gear at the time?
I managed to restart the car and limp the car in gear further up the road, however the car would not rev once started as I only managed to get the car on full throttle to about 1000rpm only.
Once I got the car back home after being trailered, I checked the car over. I could only turn the crank over part way before there was something locking the engine. I discovered that the timing had jumped out of alignment and that the recently replaced timing belt was slightly loose. The belt was frayed in places with some of the teeth slightly rounded. I decided to take the belt off and reset timing marks and readjusted the static timing with the same belt. The car now runs smoothly. I also checked compression levels as I thought that if the timing had slipped then surely valves would have bent. Compression levels were 11.5, 11.5, 11 and 11.5 for all cylinders. The top end cam area sounds slightly noisy however I always thought valve clearances were needed to be checked. Starting from cylinder 1 these were .021, .018, .017, .017, .018, .014, .015, .023.
Now I want to ask you guys why the cambelt jumped and why the engine still runs after I've corrected the timing as I thought the valves would have bent. I'm frightened that the car might just stop again whilst driving and cause the same problem.

maybe your cam belt was too tight....

have a look here someone had the same problem...plastic cam wheel problem? belt tensioner too tight?

Thanks for the additional post Pete! I have noticed there is a little bit of play on the resin cam pulley. What I mean is, the pulley seems to rotate back and forth when positioned on the camshaft however this is only minute. This could be the problem as it's the dreaded resin pulley. Perhaps I'll replace it with the steel pulley Eurosport supply.

lets hope it is that keeping the remedy nice and simple

Good shout by Pete - it would be a very good idea to replace that cam pulley asap!

I also changed the pulley on one of my 1300s some time back, even though it didn't actually break, it looked on the verge of disintegrating and I had heard all the bad press about them. Even it this does not cure your problem at least its peace of mind and one thing ticked off the list. And at that price from eurosport, you'd be mad not to. When I bought mine, I ended up buying it from the states for at least double that, then i got stung by the dreaded import tax!

Well, I have now fitted new steel cam pulley, cambelt and adjusted valve clearances. The car started and I drove the car down the road and all seems fine!!!!

fantastic!!!

Excellent
