Stilo 1,4 timing marks

My 1.4 -07 Stilo is not starting any more. One day I was starting it, it just tried to start once and then just cranking. Cranking sound is now little bit strange and I'm afraid the timing belt has jumped one or more steps off, has there been this kind of issues with these engines? Timing belt is not snapped, that I've already investigated. Is there some original timing marks somewhere on 1,4 Stilo engines? It would be great if there would be image of this marks if there are any.

If timing belt has jumped one or two steps off, does it mean that the valves are already damaged?

Re: Stilo 1,4 timing marks

From what you say, I can't envisage a failure mode which would allow the belt to say jump a few teeth, but then continue to function. Okay a knackered belt can shred a number of teeth, but if it did it wouldn't move when cranking (assuming its not broken and does move when cranking ).

Consequently I would look to another cause, starting with fuel, ignition and compression.

Re: Stilo 1,4 timing marks

The belt is moving when cranking, I took the belt cover away to see the belt clearly. Cranking sound is not metallic sound and there wasn't that kind of sounds when problem appeared first time. Cranking sounds fast, like it is missing pressures.

The belt moving is good, so test the compression .

Re: Stilo 1,4 timing marks

Definitely, I've to take it into garage first someway. I'm pretty sure that there has happened something related issue and that's why I'm asking, is there any original marks in these engines where to compare current positions of pulleys? Also I'm beforehand interested, can there be big damages already if it has jumped a teeth or two, is there any reason to play with it anymore? Or should I just send it straight to nail factory.

Re: Stilo 1,4 timing marks

Is it a 8vor 16v engine
I believe the 8v has timing mark's while the 16v does not

Re: Stilo 1,4 timing marks

It seems to be 16v engine. :/ I looked under the belt cover again and I was hardly able to see some white marks on cam pulley and on head, these are possibly did by earlier mechanic? I didn't yet get enough visibility to crank shaft pulley to see is there any marks. Hope those will be found there.

Re: Stilo 1,4 timing marks

The most likely thing to go wrong is the most likely thing to go wrong... so let's rewind and start at the beginning before we dismantle the engine...

When the engine cranks, do you have a signal at the injectors (and is there fuel being delivered to the fuel rail)? And do you have sparks at the spark plugs?

Engines really don't jump their cam-belt if they can possibly help it. More likely you've lost fuel or sparks or both, for some reason.

If the OP has to take it to a Garage to test the compression, I'm pretty sure testing the fuelling would be a step too far . Seems to me that his preoccupation with the timing marks and belt may suggest that he and/or a mate have already had a go at changing the belt, cocked it up in the process, and are trying to get it back to where it was before he does anything else . Well that's my thought of the day .
