Diesel leaking into motor oil

Chevrolet Captiva 2010 Turbo diesel 168932 miles

My Holden captiva 2010 has started leaking diesel into the motor oil , which causes the diesel fuel to run out extremely fast and for the oil to over fill and leak onto the engine which then brings out black smoke...
I'm not currently driving it , it's sitting in the garage collecting dust...
We've talking to different mechanics but get told different things each time...

Would anyone know where or what the problem would be so we can fix it...

Thankyou

The Injector sits partially inside the tappet cover with the oil, so when a seat leaks it goes directly into the oil. That's one scenario I read some Captiva owners had. Others point to the DPF injecting excessive fuel, but I would think that would take quite a lot of times to create any noticeable dilution through the piston rings, and white smoke would be heavy out the exhaust if it was doing that. I have one doing the same thing, a 2010 Captiva 2.0L. Within 1 month of driving it can collect between 1 to 2 litres of diesel in the engine oil. Dipstick reads double the full mark. Injectors are done, DPF if perfect, Turbo runs full boost, no power loss when driving, very smooth running engine. Never see any smoke out the exhaust, yet diesel still pours into the engine from somewhere?

Valves twisted Solved

Chevrolet Captiva 2009 85500 miles

Hello everyone. I own a Captiva and, due to a mineral oil shortage, the oil of my vehicle was changed. From that moment, it did not worked properly and it felt as if it were a cylinders failure. I changed the oil back to the synthetic one it had before, but the failure persisted. Since then, the car has not started working again; apparently, the engine got stuck but I cannot understand why. The compression has been checked, noticing that the front cylinders do not have any compression, and surprisingly these cylinders' valves have been twisted. When checking the camshaft's solenoids, we noticed that one of them is not working but it is not understood why this happened. I would appreciate any information you could give me.

If your valves are twisted it is due to the tappets, that work with an oil pressure. You did wrong to change to a mineral oil because its viscosity is higher, and the hydraulic tappets do not release such oil. It was useless to change the oil back because the damage to the valves was already made.

Oil pressure failure

Chevrolet Captiva 1012 130000 miles

I've changed from a sythetic oil to a semi-synthetic one and an oil pressure failure is indicated. What should I do?

The problem is that, if your car came with a synthetic oil, you should not have chaged it to a semi-synthetic, because even the engine can get damaged. Change it again and your problem will be solved.
