Hello all, I've got a transit mk7 2012 jumbo. The van runs fine. I had an oil, oil filter, air filter and fuel filter change last weekend as it was due one and the van ran fine all week. This morning, as I was on the way to work I noticed the red oil light had popped up and the turbo was making a slight whistle. I took the van home, topped up the oil to the correct level and the turbo noise I think went a little quieter. No idea where the oil is leaking from??? underneath is bone dry and the whistle is annoying me. I haven't lost any power nor do I have any smoke either on idle or under acceleration. I've had a transit where the turbo has blown previously and the noise was much louder than my van so I don't think it's blown.
Any help will be much appreciated as I'm panicking and have been all day
Thanks in advance..
