Regarding the timing, it was fine before i started working on the intake manifold. i can't see how the intake manifold and injector removable can offset the timing. If it is a timing chain issue, then it's an amazing coincidence a bad chain causing to mess up the timing on the next start after. But hey..... those odds of such a coincidence to happen to me is likely. I am that cursed. By the way, if timing was off, surely i would get a number of codes. But i will check it out anyway and thanks for your tips. Last edited by JustBill; 05-08-2024 at 10:25 AM. |

Slight mistiming generally gives a cam sensor fault, leading the novice to replace that sensor.
Testing for firing with another fuel (or even a splash of diesel into the intake) is a good way to see if the mechanical aspects of a motor are sound. |

Still not getting the full 12v power into the sensor which is strange but getting the 5v from the signal wire which is supposed to. To verify timing, i will check and lineup flywheel with the pinning hole. If i do that, would i also need to remove the timing belt cover and check that the camshaft and crank all lineup aswell? So it's virtually doing a timing belt change without placing a new belt? |

It’s not a two minute exercise, no. Less effort than changing the belt, though.

It also used to kill them every 12 months until I MacGyvered in a massive DIN85L sized battery. You got a battery charger? Put it on the car overnight and then try start in the morning and see how you go. Also check condition of main earth cable, on the Focus its on the passenger side shock tower, unsure on Mondeo but could be similar as they share a platform. |

I'm starting to believe i have a timing issue which i'm going to need a new belt. **** me how did i get myself in this mess. Just learnt from Alan Howatt in one of his videos, that the high pressure fuel pump needs to ne timed also with the power train timing. If the timing is out with the fuel pump you don't get the injector spray in sinc. Maybe that was the original cause of loss in power. Last edited by JustBill; 05-08-2024 at 08:58 PM. |

They needed to get some specialist in to get the snapped thread out of the crankshaft, which took him all day. Be prepared for a fun* time *will not be the usual definition of fun If you got good quality jumper leads, get another car onto it, but go to the negative terminal on the Mondeo, not the Mondeo body earth as its not big enough to get enough current through to turn over diesel engine fast enough to get it to fire. If its like the Focus its a pain in the *** because the negative terminal sits under the wiper cowl, might need to take off the wiper cowl to get enough clearance. How good are European cars? |

Re timing, i'm just going to check if the timing is ok and adjust it if need then retention the same belt, thats if the belt is one piece. So i wont need to unbolt the balancer pully. Last edited by JustBill; 05-08-2024 at 10:42 PM. |

Update:
* I opened the timing case and found the belt intact. * Then i checked if the timing was accurate. * Locked the flywheel through the hole behind the starter motor. It definitely went in as the crank wheel could not spin (due to the pin locking the fly wheel) * Checked if the hole on the cam cogl lined up with the hole on the back which is about 4 o'clock. Low and behold..... the hole on the cam cog was facing 2'oclock * Removed the belt from the cam cog, with the fly wheel locked into place, turned that cam cog from 2 o'clock to 4 o'clock where the 2 holes lined up so i can put the bolt through it. *then put the timing belt on. Now going to put the pieces back together again and see how it goes. Question... How is it possible for the timing to go off with the belt not snapped and still teath on the belt? Why i ask is can it happen again. |

The crank sprocket is “slip and grip” (my description, not the official term). It relies on that massive torque of the centre bolt to provide clamping force that holds the sprocket in position. When you’re breaking or tightening this bolt, it’s necessary to use a counterholding tool - not to rely on the crank timing rod for you use for checking.
Perhaps the bolt wasn’t tight enough and that’s how you slowly got out of time. |

On the positive side, it sounds like you’ve possibly diagnosed the root cause.
If the crank is located and locked correctly per the pin in rear of flywheel, and your belt driven cam is correctly timed, it doesn’t matter where the lower sprocket and belt are when you tighten the centre bolt. It’s just got to be insanely tight. Peugeot say 70Nm +60°, it’s a single use bolt. Use the old one to make a chasing tool and clean the crank nose threads. |

You’re too kind. I try to help when I can see someone is making a serious effort themselves.
Hopefully you’re close to a solution, counterholding the ring gear while you lock that bolt down super tight, will be a decent challenge. |

I will do it in reverse to when i loosened the bolt. Used the breaker bar and added a 1 meter steel pole as an extension then used both arms to lift. I will also add thread loctite glue to the bolt. Then good luck to anyone needing to take it off again in future.
