Spot the part competition

[datalas]

Having just removed the following from the sump on Roo I'm inclined to believe they're not a service item...

However,  just what exactly is it part of?  My guess is a lower piston ring (one of the oil mopper upper ones)

roughly 15mm in length for the longer one,  out of a 200tdi ...

Looks like an oil scraper ring to me - either side of the gap. Bit worrying really as you don't know if they were replaced and a bit of the old one dropped in or not.

Yes. I would have said the same. Oil Scraper.

Ouch. :(

[Ralph]

I agree it is part of an oil scraper ring.
However i would not be to concerned if the engines is running ok i.e sounds ok and not burning oil because for something of that size to jump out of its groove in the piston there would have to be a considerable amount of damage to the piston itself which would more than certainly be noticable in the running of the engine.
I would say that this part and piston has been replaced in the past though how they missed these pieces i dont know

[beast5680]

yep i would agree as above :shock:

[datalas]

Engine is making clunky clanky noises :(  and is hence out of commission in light of it being fixed.

Engine is certainly rattley, but you'd think it'd make more of a rattle than that, certainly to let the bits fall out,  however the edges look like it's been broken for a while.

Oh well, we'll have to see what damage is done when we take it apart...

[clbarclay]

What does the eingine (piston and bores) look like from below are there any signs of damage. though not the easiest thing to do if its still in the disco.

If the engine is as bad as you say with no other obvious cause then a full strip down and new rings + bearing shells would'nt be a bad thing for it.

[datalas]

yeah, it's off the road till we can take the top and bottom off, then we'll see what the damage is.

Not a great deal of point speculating at this point since it could involve any amount of work I'd guess, from replacing the rings to replacing the pistons to reboring the engine.

the edges of it aren't as shiny as I'd have thought they should be, so it's been "wrong" for a while, although how you get the rings out past the pistons is beyond me..

[datalas]

Stripped the motor down, took the head off etc .. and found this...

Hmm...

I think I could do with a hug :(

angle grinder will sort that out  :lol:  surprising its just there though and not all the way down :?

You must be nuts angle grinder?? Honing tool! about £20 from good tool shop.

A three legged adjustable device with grinding stones on each of the legs. some are fixed and must be used in a pillar drill they do make a flexible one though which you can use in an electric hand drill.

Hmm we,ve not heard of sarcasm now have we :?  :lol:

That might be a but too deep for honing, they are only used really for de glazing the bores

What shape are the pistons in?

You may be looking at a rebore, and new piston(s), also need to check the big ends and shells see how bad they are

Depending on your resources and how deep your pockets are, fix and rebuild or replace with another engine

Shame they dont use wet liners, make life a lot easier on these sort of jobs

Don't know what the pistons are like as I haven't removed them yet, however I'm assuming that the damage is a little too deep for it to have a shall we say, positive effect on compression and hence am probably going to go down the replace the engine and then rebuild this one at leisure route...
