--- Quote from: "drum" ---That would tell me if it was one of the three, but would it tell me which??

I hve a compression tester for Petrol engine (screws into the spark plug hole), I guess that won't work for diesels.

Nope, plus a diesel compression is much higher than a petrol engine, so you need a gauge with a higher reading...

Hrmmm, as for damage casued??

Was there any water in the oil (i.e. milky colour) or was there any water in the oil??

Water will usually bend a rod....  I've known this in a Nova diesel.
Engine ran ok, but produced quite a bit of white smoke.  When we took the head, one piston was found to be almost 1" lower than it should be!!



--- Quote ---might be worth removing exhaust and standing up some where to allow water drain out of silencers first before condeming engine

No need to this, as water will be blown out anyway... I would, though, make sure the inlet manifold is empty.


Other possible damage:

Bent Con Rod (most likely)
Cracked Piston
Bent Exhaust Valves (quite common)
Or you may have caused the cambelt to skip a tooth or two.
Damaged Head or Block (i.e. cracked)

Most likely damage though is bent cond rod, or damaged valves.


Really is an engine strip down to have a look, and to take some measurements.  
A 200Tdi is very easy to work on, will only take couple of hours at the most to get the head off.  Pm me if you need any info.

A compression test will only confirm that 'somthing' is wrong, but won't actually tell what it is.....

Time to get your hands dirty  :wink:

drum:
Thanks Ian.

Already emptied the plumbing, right down to the inlet manifold. Got quite a bit of water out of it.

There was a small amount of water on the dipstick, but the oil itself came out normal black, with no traces of water mixing.

I'm thinking bent con-rod might be a possibity now. I would expect the smell of unburnt diesel though. i.e not enough compression to ignite it.

I'm guessing that if we have bent one, there is a fair chance that the piston is now running out of line, and will wear the bore a funny shape pretty quick. So maybe don't run it for the week to see what dries up.

Pull it down, you're lucky to get away with a hydraulic'd petrol, never  mind a diesel.
Summat will be broke.

Double check the timing on the way down as well, and make sure timing gear is OK, but Im guessing ROD bent.

Oh yeah, get a snorkel. :wink: (or a longer one if already fitted, I know what yr like Drum)

drum:
Wasn't me this time. It was Johnnie doing anchored fish impressions  :D

rollazuki:
He doesnt like that truck does he!!!
