A good scare

I cleaned out the intercooler about 7k ago and replaced the intercooler hoses with silicone hoses. At the time I was surprised by the lack of muck in the intercooler compared to when I did my disco but I will check the hoses in the morning as a precaution.

Used to work on locomotive diesels and Rail motors with GM 2 strokes .If we suspected fuel in the oil, we would drop a bit of oil from the dip stick onto a piece of brown paper. There would be a dark blob on the paper and if there was fuel in the oil a lighter brown mark would spread around the outside of the oil mark as the thinner fuel would spread out more. This was just a preliminary agricultural test.

I have had this on the D1. Not the floor mat... but the kick panel under dash sagging and resting against the pedal control arm.

Yep this happened on our 200tdi defender....

There is a light coating of oil in the lower intercooler hose bit hard to.say if.it is too much or.not. How can you check whether the turbo seals are ok? The defender has been runnning fine since then, apart from a brake issue today when I was offroading but that's another story.

Turned out that engine oil from a faulty turbo seal gradually filled the intercooler and manifold to the point where oil was blown into the engine and it took off. we drained half a litre of oil from the intercooler.
Check for excessive oil inside the turbo hoses. A light coating is aparently ok.

Don't know how to check the turbo seal, but you could poke around in the bottom of the intercooler with someting soft and see if it comes out wet.

Although we thought it was the turbo, it could also have been the engine breather cyclone (on the rocker cover).

Cheers,

That's a handy tip, will try it tomorrow.

Thanks Terry. I will poke around in the intercooler and see what shows up. Given I have cleaned it out not long ago it should be pretty clean.
