2.2 HDi Engine Woes

Post by Geoff Lebowski »

It's actually a Peugeot 406 Coupe but I know the engine is common.

Put briefly, my friends auxiliary belt snapped and caused the engine to stop. I've not seen it myself but have been told the cambelt has snapped also. Not sure if this is so but the engine won't turn over - according to the garage.

I've been asked if I'm interested in tackling the job myself,but I will decline, based on the fact it looks a more complicated machine than the 2.1 XUD11BTE.

So, if there is a likely outcome, what would it be? Do the rockers break up prevent the valves hitting pistons like they do in the XUD11? Or is this likely to be a head rebuild job with bent valves?

I think , that rockers get broken, so all valves remain shut. This does not explain why it won't turn over. Normally a reasonable job, but you will need to remove the inlet manifold which is part of the cam covers.

What an absurd idea! The inlet manifold being part of the rocker cover....anyway, looking at the drawings on Cit Serv they look like pressed steel components and unlikely to break, unless I missed another part that might break. I'll take another look

Dont touch it!

Its higly likely the Inlet wont come off, this is because the injectors need to come out to get the inlet off... and getting the injectors out will either be IMPOSSIBLE or easy! And if the injectors are stuck in.. its scrap. Dealers themselfs have even scrapped many engines due to injector refusal to come out.

Then the engine is a 16v twin cam engine. Ive never been inside one, but the valves could be inclined at an angle which could mean bent heads at the base of the stems...

The 2.o 8v engine valves are directly over the pistons, and they do break the rocker fingers.

The Cam belt on the 2.2 16v drives just the rear cam, the front cam is driven by a chain from the front.. So the belt is actually fitted like the 2.0 8v, rear cam, fuel pump crank and water pump.

So the biggest issue Is getting the injectors out. And thats the Do or not do question which answers the rest of the job.

Even I wont touch a 2.2, only to remove it and throw it away...

I recently replaced my (well work did) engine due to water damage.

The injectors on the old 90k engine took 5 mins to remove, will not take long to see if they will come out. I think I have the head from my old engine knocking around at work, the damage to my engine was bent pistons. removing the head is a task I was told due to the engine being on a slant.

Thank you both, no I won't get involved Paul, useful information about the injectors. So, if you can't get the injectors out, you can't remove the head which makes any head work impossible? That's crazy!

I have worked on 2 of these engines and yet to have an issue removing injectors?? - Having read the horror stories, i decided to have a go anyway and soaked them in 'Plus-Gas' overnight and they appeared to come out as if loose. I did this also to the second one with similar results.
Sorry but I did not try to remove before I soaked them - should have I guess.

I thought the 'stuck' problem was partly caused by a potential design concern, ie rain water could collect around them on certain models ?

The 807/c8 problem is breaking cam belt problems because of the water drain and engine position design

water gets onto the belt past the cover and snaps the belt.. they then cannot warm the engine sufficiently to get the injectors out and that's the issue.. the black sludge goes rock solid quickly when it cools that's when the problem starts.. if you notice black sludge and bits of coal around an injector get the engine as hot as possible and get them injectors out asap..
