I have a 2003 Peugeot boxer with a 2.2 hdi.
Water pump gave up recently and was using water every 100 miles or so, new pump time thought I would change all the belts whilst I was there as it has been 6 years.
Completed the job
Turned over by hand no with interference
Started and it ran and I wanted to take it on a nice long test run.
About 30 miles in it started making a loud 'puffing' type noise. Sounds like it's pushing back through the intake?
how ever still runs and turns over by hand with no issues. Idles fine No warning lights on dash.
I suspect the timing may have jumped a tooth? So it's now ever so slightly out?
So my questions are, is there a specific way to tension these engines that I may have missed? Causing it to jump?
OR
I may have re timed it ever so slightly out
If not how are they timed from scratch? So I can start again from fresh and get it bang on.
Or does anyone have any other ideas? (I'll get a video of it running later so you can see for yourself)
Thanks
