Disaster struck returning from work today. Had gone 2 miles with no problem then the rear looked like I'd used a smoke grenade and the engine started to rev it's bollocks off; it wouldn't turn off by the ignition so I banged her in 5th and stalled her. Being only a mile from home I waited 5mins and started her and drove off slowly, smoking excessively.

Once home I checked the engine. Engine oil is literally dripping out of the airbox - clearly the engine has been pressurised to the extent that has forced a lot of oil through the cyclone filter. The dip stick indicates a very low content.

There doesn't seem to be oil around the cylinder head joint.

Any thoughts?

I've ripped several 2 strokes apart but never a 4 stroke so all help (especially around Lichfield) would be appreciated.

Gutted. :( Sorry to hear that.

Im not that mechanical and dont know a great deal about turbos or 200tdi's but im no stranger to work.

Give me a shout if you need a hand? im not working until the 1st of may.
 
My money is on the turbo you did very well to save the engine. Also very brave to restart it after the fault. Replace turbo wait till night fall to start and burn all the oil out the system.
 
good job stopping it.

I've never done it, but i'm sure you can remove the turbo and run without it until you can get it fixed/replaced.

Someone else might have more info on what you need to do.
 
Just pulled the intercooler hoses off and they are dripping with oil, as is the airbox to turbo hose.

Can someone check their turbo for: when viewing it from the front I can see a rod with a nut on with what looks like propellers on. There is no movement back and forth but there is definite movement up and down.

I need to confirm exactly what the issue is before spending more of my hard earned cash that I don't have.
 
Can anyone recommend any turbo specialists?

LROI have an advert for turbocentreuk on pg 232 - anyone dealt with them?
 
there should be a very little movement up and down.... its a very good chance its the turbo

glad you stopped it, i have known people to get out and run
 
Good job on stopping it mate and it has a good chance of it being the turbo if not i will be surprised
 
Shagged turbos normally display lots of movement in the plane of the shaft, so in and out. All non roller bearing turbos have journal bearings where the shaft float in oil, hence you have some movement side-to-side, even when new.

I have to admit it sounded like your turbo, but unless there is movement as described I'm less convinced.

When my sister in laws ford mondy tdci blew it's turbo the bearing completely let go, oil was everywhere and the blades were completely munched! I went to check for play before removing it, and the shaft nearly came off in my hand!

It might be worth doing a compression test, or better still a leak off/down test - just to be sure....

It definately sounds like the turbo is knackered. I would hazard a guess that when the oil seal failed, the bearing was starved of oil and overheated.
 
Thanks - the runaway engine was a real adrenalin moment. There's oil just about everywhere.

Don't have the kit to do a compression test, and what is the latter test?

Have found the turbo repair kit for £70, just worried about the comments on balancing due to the speed it rotates.
 
Hi.
Latter test involves feeding the engine with air from a compressor - it goes into the cylinders via the glowplug/spark plug hole and is held there behind a pressure gauge.

You watch and listen while the air escapes via leaking a head gasket, worn bore or broken ring, broken valve etc etc.

Unlike a compression test, you can see air bubbles appearing in the rad or hear air coming of the exhaust/inlet or dipstick hole and identify the problem.

A well equipped local garage should have both testers.

Edit: They balance turbos to something daft like 120,000 rpm, and in operation they reach 60k+ so despite having very little inertia, their balance is very important and I don't think it would be wise to service it without doing so.
