Got a tdi 200 disco (thanks Dan m8 pucer truck) I no there old but touch wood very trust worthy, 190000 mile but drives like allot less, and I recon Im getting 30+ miles out of it (then again Im a steady 55-60 mile an hour driver, shes got colway mt on steel moduals (which Iv painted smoothright black after a good wire brushing), you wont win any races but if you want speed buy a sports car or a v8 :lol: :lol: :lol:, all in she performs well off road and water no worries

sounds like a goodun, just keep ontop of the rust and it'll serv you well :cool:

190, 000 miles might just mean it's sat rolling along some on some big journeys. It's cold starts and stop starting that wears them out.
A good sign is if they don't breath too heavily, unfortunately you can't ell much from the engine oil.
-
thats wnat I was thinking, when you say breathing excuse my ignorance what is ment by this term ? does it mean how clean its burning?

Engines have a breather pipe that vents the oily side of the block, not sure where it comes out of on a TDi (off the top of one rocker cover on a v8) and the are connected to the air intake so that they don't dump oil (vapourised) onto the road. Most engines have a swirl pot fitted which using the same principal as a dyson (its been around a lot longer than funny colour vacume cleaners) removes most of the oil from the breather and returns it back to the sump.
If there is relativerly a lot of oil (or even water :roll:) coming out of the breather then its a sign of a worn engine. If you temporaryily disconnect the breather pipe from the engine side of the swirl pot or the air box etc. and stick it into a bottle, then run the engine and see what comes out.
On the old VM engined RRC which didn't have a swirl pot then you can didn't have a swirl pot, you can tell ho much oil is getting sent outthe breather by how long a new air filter lasts before its ends up with more oil it that a series oil bather filter :lol:

thanks for that

On the 300 TDi the swirl pot, (or swil pot) is on the driver's side and it's not much use TBH. It's then piped round the back of the engine to the turbo inlet hose. Nice oily turbo anybody?
If you find lots of gas puthering out of the filler hole with the engine running it's a bit worn, some is expected as it's piston ring blowby but not a jet of smelly air. If it pulses then think busted ring.
On some petrol engines that have postive crankcase evntilation you actually get a partial vacumm under the filler cap, it protects the oild selas form leaking as well as containing all the oil vapout and blow-by.
Never get it on a Deidel though.
