V50 Engine 2.0D : Bent rods?

[miksu]

If the egr is not blanked that is the first thing to do. You can just leave the egr cable disconnected.

videos are great!
thats unburnt diesel. either because teh conrod is bent and you have low compression, or the injector is kaput.
do you have one of how it is when it is warm?

The injector results - i dont truly know what they mean, but soime of the readings vary quite a lot and some of the pass/fail colum has crosses. I would focus my attention there (i appreciate thats where you started asking questions, but its difficult to understand a job with only half the story).

The issue is definately only with one cylinder, which is good as it means you can do some comparison stuff.
having seen that i would not rule out a bent con rod.
To check for a bent con rod, remove the injectors, and measure from a fixed place, the maximum height each piston comes to from the fixed point and compare.
However, seeing some of the injector results, and the fact it is a bad starter, id put a set of new injectors in it (measure con rods whilst the injectors are out) and be confident in one of the two is the issue.

I actually still haven't figured it out..is the egr valve and throttle body the same? If not, can someone show where to find it?

I don't have video with normal start, I can make it tomorrow. But there is nothing interesting, no smoke, no idling, no choking.
About the injectors - the crosses mean that injector have failed the norm of flow. Example, the norm was 2,0-3,6 mm3, but injector made 1,9mm3. Is that injector have to be changed? Do i need to change all of them?

id take them out, measure your piston heights and then if you ind nothing, swap the injectors out

Has anyone considered a leaky valve? You need a compression test doing, I'm still not convinced it's a bent rod even though your car sounds rough.

[Bloders2]

good call.
as i mentioned a leakdown test earlier. I prefer them to a compression test as you can hear where / if the air is escaping to.

I have never heard of these engines bending conrods. We've seen loads of faults on this forum but never bent rods. I'm looking forward to see the conclusion of this now.

Thank you all for information. I will try to measure compression first to get clear with rods. Then if that will be OK, will be looking towards injectors What about that egr? Where its located? I will be updating news
