Thread: Urgent mechanical advice required!

I-+'ll post this down in the WA section too, thee could be someone local for you...well there is always someone local in WA

Sounds like the old head gasket trick ! 300TDI at 300000k's !! when was the head gasket last done . Pity your so far North , get it to Newman and we will fix it for you !!

Any idea what's going on in the cooling system?

Is the coolant level changing? Using water, pushing water out?

Oil in the water, water in the oil?

Running hot?

Sorry to hear of your troubles. If the engine runs well then that is a start! So I take it idle is smooth and even on all cylinders?

If I understand the symptoms, you have BOTH smoke from the exhaust at low-med revs AND an external oil leak?

The first step will be to trace the external oil leak.

The oil that the engine is burning must be either getting past the rings, valve stem seals (unlikely), or via the turbo. The turbo would typically be the first port of call.

Removing the oil filler cap while the engine is running will tell you if the engine is breathing too heavily (i.e. worn/damaged rings).

Any decent mechanic should be able to do all of the above to diagnose the problem.

Sorry to say that if the guy who owns the mechanic's shop is the same as the guy who owns the repco parts store, he did not believe me that landrovers are now metric, so will probably be using imperial spanners to work on your landie...

I hope you can grin and bear the tirades about how landies are crap and the only suitable vehicle for the kimberley is a landcruiser.


EDIT - JC is the man who knows. Head gasket it may indeed be.

doing a shifty rebuild of the engine should take a decent mechanic less than 3 days to do, and about a week delay on parts.

I'd almost bet that finding a semi decent second hand donk from a wreck, pulling it and having it mailed to and then installed would cost you less than you would loose out on selling the deefer and then buying another tow vehicle.

get the mechanic to pull the crank case ventilator off start and run the engine and see what comes out of that.

pull the glow plugs and see how they come out after the engines been started and run briefly.,

do a compression check

Did you overfill the engine oil at some point?

is the cooling system pressurising?

I suspect rings (which isnt that big of a deal you can do them without taking the engine out.)

Hi Mark and Sandy

First undo the hose going from the turbo into the bottom of the intercooler.

If it is very oily, get another turbo and dont run it until its installed because if the turbo seal is crook, it may get to the stage of a runaway motor.

Then if that pipe is clean, scratch that problem off the list and then go on with the order that Blknight.aus has laid out.

Cheers Arthur

G'day Isuzurover - see responses below on specify symptons as outlined in your response.

When at road speeds there is no smoke, but perpahs the wind is taking it away before I see it -I don't think so though. Lots of oil splatter in the engine bay, top and bottom - particularly around the engine breather filter. Oil been blown right through back onto the front of the camper trailer

The first step will be to trace the external oil leak. I suspect it's around the engine breather filter, but I can't actually locate the leak. It's seems thickest around this area. Breather filter and hoses coated in oil.

The oil that the engine is burning must be either getting past the rings, valve stem seals (unlikely), or via the turbo. The turbo would typically be the first port of call. That's what an RAC man I spoke to suspected, although, turbo does seem to be working fine . . . ?

Removing the oil filler cap while the engine is running will tell you if the engine is breathing too heavily (i.e. worn/damaged rings). RAC man suggested that also; no sign of smoke coming from oil filler with cap removed and engine running . . .

Any decent mechanic should be able to do all of the above to diagnose the problem.

I hope you can grin and bear the tirades about how landies are crap and the only suitable vehicle for the kimberley is a landcruiser. Yeah, it starts to wear thin doesn't it ! But then, with over 300k on the clock, no one could deny the old girl hasn't done well - even the toyota crew!
