2005 2.2 DCI broke auxiliary belt a few weeks ago. Now developed a massive oil leak. I’m guessing a bit of the old belt got stuck behind the pulley and destroyed the seal. My question is how can the engine oil be leaking as , as I understand it, the oil seal is behind the timing belt? How much of a job is it to replace the seals? Cheers

I have seen bits of broken aux get belt trapped behind the timing belt pulley. It can be compacted into a hard lump and need serious digging to get out. Haven't seen a crank seal damaged that way yet. I'd say you're very lucky that the timing belt didn't come off. In fact, it has probably taken a hit and it will have to come off anyway to get at the crank seal.
How big is the leak and are you sure it's coming from the crank?

Hi , I’m struggling to see how it could damage the seal as it’s behind the belt? I’m wondering if it might not be the problem at all. I’m reading about a cover that blows out and that makes more sense as it’s a lot of oil that’s leaking. I’ll try to have a proper ok today👍

Take as fact that if an auxiliary belt breaks up, bits can get behind the timing covers and cause havoc.
Get the timing covers off and take a look.

Not good news but at least you know the problem now and the answer.
Enforced timing belt change and sort the seal while at it.

Yep☹ Belt done about 3 k ago but oil will kill it. Total PITA🤨 Like the car but just seems hassle after hassle🤷‍♂️ I have a Cayenne Turbo that runs like a watch despite being a lot more complicated machine. I will say the alternator failed a few weeks ago and the auxiliary belt the garage refitted was totally fkd....it lasted2 mil s then let go. Why they refitted it I’ll never know🤷‍♂️

That's a bummer. Lost the ship for a ha'pworth of tar. New belt should be a reflex with a new alternator. Then you have some punters moaning about the life left in the old belt. All the same they should be taking the blame for this.

I’ll be pushing for a 50/50 on it for sure. The belt was so bad I could almost pull it apart by hand. The car had a diesel leak over a long period and it had been dropping onto the belt🤷‍♂️

Turns out tha timing belt doesn’t go to the crank pulley on this engine and just needed the seal changed. 25quid plus I he seal👍 A good result

Just me but any timing belt that doesn't go to the crank pulley is a joke :unsure:

Okay, I'm confused.
First off I'm glad it's sorted and at a decent price.
But what do you mean on the timing belt?
2.2DCI engine will be a G9T ???
If so, the belt is a normal drive direct from a pinion on the crank.
Or have I got the engine type wrong?

Indeed.
I stand corrected, thanks.
So I assume that there are internal gear drives between the crank and timing pinion, similar to many pushrod valve systems where the cam would be in that sort of position?

There is an internal balancing shaft driven and timed off/to the crank with the nose of it driving the timing belt.

This is why even Porsche owner can now do Renault timing belts too :p

New one on me. Assume one teeny thing about a Renault and you will be wrong :)
