2.2 cdti Loud engine knocking noise

Squirting washing up liquid onto the head where the injectors are will identify exactly which ones are leaking. Do it on a cold/warm engine though, not hot.

I replaced a seal on number 4 for the first time a few months back. As others have said it's not too difficult but you need to be methodical . Coke helps btw.
 
I did suggest the coke method to my mechanic but they were saying it wasn't a carbon build up issue and that it was probably rusted itself in.

Could I try soaking around the injector with WD40 and leaving it for a while to see if it works its way down to the bottom? Also seen carb cleaner used in another video on YT.

He said he broke a few of his tools trying to remove them so they are really seized in.
 
Douse them in Coke overnight.. then place a block of wood over them and crank the engine.. they will pop out eventually. It's not the safest method but it works.
 
So, had it taken to a diesel specialist and it's a engine problem for sure. One cylinder is knackered. So on the hunt for another engine now...Merry Christmas!

Where's the cheapest place to get OEM parts online?

I'm thinking while it's out I should get them to fit a new timing chain, clutch and DMF, fuel filter....

Anything else to look for while it's out?
 
Secondhand cars are really cheap and it looks like you're planning to spend a lot more on the car than its ever worth. But if your really in love with that old car then why can't the diesel specialist tell you where to get all those parts?
 
They probably can but guessing it would cost a bit more, just seeing if I can save some money where I can.

If I hadn't have spent so much on this car already (buying it from a dealer/stealer and some maintenence bits) I would just break it and buy another as you can get them fairly cheap. But then selling it as parts or repair as it is would lose me a lot of money as they selling for even less.
 
What is he saying is actually knackered? Is it the piston ring? Have they got the engine running now? Is it burning oil, or can you hear any bottom end knock? Did something fall out of the injector into the block?
 
Sounds like something top end damage rather than bottom end.

Still need to remove the head but he thinks the chain jumped and cause a valve to be stuck open slightly then making contact with the piston bending the valve. Should have the head removed soon and will find out for sure but not sounding good.

You can't pick it up in the videos but It's metallic sounding clatter.
 
I’m breaking a 2.2 d with 250k engine sounds exactly as stated above and shed load of under bonnet smoke.
I’ve stripped most bits to fit into my 2.0 se now with full leather.if anyone needs bits I’ve plenty left msg me 07775726211
 
Sounds exactly like my cdti , same thing in slow moving traffic , couldnt pulllovrt , next thing a bang , it put a rod through the block , yhe mileage was 51k when it happened . I could only surmize , it was the oil pump or maybe previous owner had put in out the wrong oil

Ok so had to get the accord recovered by the AA due to a very loud knocking from the engine.

The car is an 05 accord 2.2 cdti with 105000 miles on the clock

I first thought the sound was a flapping belt, but after popping the bonnet with the engine still running the sound appeared to be coming directly from the block.

The car srptarts and runs and doesn't appear to be lumpy... But the noise is LOUD and sounds to be in time sync with the a single piston stroke.

Will be retiring the car till I get a chance to strip it down and take a look over the internals.

Any suggestions?

Had the same problem my engine had only done 50k put a rod through the blocj i think its something to do with the oil pump could be wrong .

So the car is back up and running! MOT'd and taxed last week with only a couple of advisory.

Replacement engine block was £750 from a donor car with apparently 60k on the clock.. no proof tho unfortunately.

Probably spent another £150 on odd bits including
  • EGR gasket that i lost DOH,
  • 2 replacement injectors that broke on the way out / didnt come out :-( grr
  • Injector seals
  • Gearbox oil
  • engine oil
  • Sensor that snapped when hoisting the engine back in DOH!

I'm not counting buying any tools (engine stand) as I'll be re-using that on my RX7 at some stage :-D

Last remaining issue on the engine front is a tappet noise that comes while engine is loaded up but stops after 3krpm on full throttle. Car sounds perfect at idle or while reving at stand still.
I suspect this is either compression leak around one of the injectors or possibly a exhaust blow near the manifold. But there's no obvious exhaust smell so im thinking it's time to check the injectors again.

Have done two long drives in her and the fuel economy is now AWESOME! Gone from getting 35-40 mpg to 50-60 mpg and im putting this down to having cleaned out the EGR pipework of LOADS of soot and also the inlet manifole and inlet runners of gunk :)

Hi! I am so manu years late that maybe you won’t even see this XD thing is you just described what happens to my car. Tappet noise on load until 3k rpm then it dissapears. Were you able to figure out what was causing it? Thanks!
