Hi all,
Hoping someone might have an idea of the source of a huge oil leak that caused me a breakdown & recovery last night...
About 10mins into a drive last night, heard my engine suddenly make a noise I would describe as 'tappetty'. I immediately pulled over and stopped the engine... fair bit of smoke, trail of oil seen for half a mile down the road, starting at the T-junction that I had just pulled out of (quite briskly!). Back of the car covered in oil (but tailpipe is dry inside!) Opened bonnet, smoke due to oil on hot exhaust and turbo.
So I'm thinking many litres of oil dumped quite suddenly. I'm hoping I stopped the engine before any damage done. I assume the noise I heard was the hydraulic tappets going 'slack' and/or the timing chain tensioner. Can anyone comment on that?
I've been looking for the source of the leak today on the drive.... and this is proving tricky! I removed the air box and was expecting it to be a leaky turbo oil feed banjo or suchlike, but it's dry around the turbos. I think the oil is from further back. There is oil staining on the larger turbo's turbine housing; but I think that is caused by oil dripping down onto turbo off the underside of the airbox, which has lots of oil on it, mostly at the back.
I'm struggling to see where the oil has come from, partly because there is evidence of oil sprayed all over at that left / back side, near the diesel catalyst. There's a pool formed on the white plastic disc thing that is on the transmission or bell housing. I noticed a lot of oil was on/around one of the two rear circular air box mounting lugs that are on an aly bracket. I also feel quite a lot of oil around what I think is the EGR connection into the exhaust manifold - what carries oil near there? I found a spare screw lying on the undertray and it matches the type of screw used on this EGR elbow, but I can't easily see if one is missing, without taking off that bracket for the rear end of the airbox.
Any ideas where to go looking more closely?
Hoping this doesn't need to be an engine out job and hoping the engine and turbo have survived.
