White smoke and shudder Defender 90 TDI

I am working on a defender 90 TDI (2013) which was in an accident a few days ago. This is a right hand drive vehicle and fell to its right hand side a few days ago. The engine was still running for around 10 seconds while it was on it side till the driver switched it off. After that the vehicle was towed to the garage where we discovered a lot of oil inside and around the air filter box , turbo intake rubber pipe and possibly also in the manifolds. We cleaned out all the oil from the air intake box and the rubber pipes , drained out the old oil, changed the air and oil filter and filled fresh oil.

The vehicle was started. It ran fine for around 3 to 4 minutes after which it started giving a few shudders and a lot of really white smoke. The engine temperature remained low and the oil light did not come on either when this happened. Also the oil level was fine when we rechecked it as was the water level.

We have tried to switch it back on again after this but each time the same result the engine starts to shudder and the white smoke starts coming out.

Would appreciate Defender TDI Experts can shed some light on what could possibly have happened to this vehicle engine.

Thank you.

tdci presumably the exhaust and dpf will be full of oil

Hello and welcome

Thank we managed to get to the source of the problem and fix it.
There was a lot of oil in the inlet manfolds as well as the intercooler which had to be thoroughly cleaned out. We also found out that the vehicle had issued with the injectors. Three out of the four injectors were giving excess fuel. Lastly whoever had last worked on the vehicle had used a bad after market intake pipe between the intercooler and the turbo which was ripped before the accident happened. After fixing all of the this, the engine was purring like never before. No smoke and at least a 40% improvement in the engines performance.

Thanks for letting us know the fix.
