Hi,

I have a 2002 TD5 110 hardtop with turbo troubles ... wondered if anyone more mechanically minded than the dealership I purchased it from can help!

My troubles started about a month ago when I suffered a breakdown; a repetitive knocking noise from the engine quickly followed by huge amounts of white smoke from the exhaust and the engine free running at high rpm, even after the ignition was switched off. The landy was still under warranty from the seller, so the 110 was returned to them and a broken turbo was diagnosed and replaced.

After fitting the new turbo the mechanic took the 110 for a test drive and about 2 miles later suffered an identical breakdown. A faulty replacement turbo was suspected so they again replaced the turbo and after testing the 110 was returned to me. Within 200 miles I have now suffered another identical breakdown with suspected turbo failure again! ... the car goes back to be inspected by the turbo supplier on Monday.

There clearly is another problem causing the turbo failures, but the non land rover dealer I'm dealing with seem convinced it's just the turbo. I suspect there could be a problem with the engine management system and have requested they get it hooked up to a Testbook, but they don't seem interested .... could anyone offer any advice or information on the possible cause?

Best wishes,

Mat.

:welcome: to LZ ............Have you an army of landies then ;)
 
you say it kept running even when you turned the ignition off.....usually when a diesel engine runs away like that its because its feeding off its own oil.....engine oil......now be that up through a breather or whatever i suggest the blown turbo is just the end result as its spinning away with no oil on the bearings....what you need to find out is why/where the engine oil is getting into the bores
 
Like swampdonkey says you're landy's running on on it's own oil. If the turbo is being changed and it's still doing it I would suggest that pistons/rings and injector seals/cracked head would be the next ports of call.

If there was a fault with the engine management system the engine would die. The ECU cannot program oil to be poured into the cylinders.

It sounds like either the injectors are leaking/the head is cracked which is topping up the oil with diesel and causing it to blow past the seals due to over pressure.

Or it could also be piston rings gone/piston holed which again causes the oil to get into the cylinders.

Either way it is NOT ecu related.
 
If it is blowing the turbo seals like that, suspect EXTREMELY HIGH OIL PRESSURE.

Get the oil pressure checked with a mechanical gauge.

If the oil pressure relief valve is jammed, pressures could easily go over 200 psi!
The turbo oil seals probably won't cope with that.

I had that happen on an Austin Maxi way back about 1973. When I fitted a gauge the needle went TWICE round the dial and buggered the gauge. I borrowed a 0 - 1,000 psi gauge fitted to a flexipipe, and when I revved the engine up the pressure shot up to about 250 psi!

Ten minutes later sorted, as the relief valve was dead easy to get it.

Check it out.

Does your sump 'oil' increase at the same time and become quite thin?If so it could be deisel getting in through a cracked head.Touch wood its not,can get expensive.
