    Default Oil in 300tdi intercooler...

    Had the bonnet up again today, looking for the oil leak which is ****ing all over the front.

    Took off top intercooler pipe - loads of oil present, pipe was wet inside.

    Took bottom intercooler pipes off - loads of oil again

    Took I/C out and tipped a half-cup of oil out, washed out, dried it, refitted.

    Thoughts were leaning towards turbo bearings going and letting oil by.

    Took turbo inlet pipe off, the compressor was ok to turn, no scraping sounds but with slight radial play in shaft, maybe 1-2mm. Then i see oil inside the filter-to-turbo pipe

    So, do i have a duff/dieing turbo OR is it all being sucked through by the crankcase PCV filter/system which feeds in just before the turbo??

    I believe the filter on the rocker box can be washed out but the book says i need a gasket to re-fit?

    BTW, the PAS pipes look ok, the oil was leaking from very poorly fitted intercoooler pipes which have now been fitted properly.

    There does not seem to be too much smoke out the back, can these engines run-away on oil??

    Suggestions???

    its probably coming from the breathe like you suggest. clean it out and use some instant gasket to refit but not loads. engine will run away but only when something is seriously seriously knackered and you would probably have it fixed before it got that bad as it would be smoking like mad before.

    Don't take life too seriously. You'll never get out of it alive.

    Good, i'll go out and get the breather and pipes off in a minute, give them all a good wash out.

    No EGR, it was removed before i got it, steel plate on manifold, nice tidy pipework, a few connectors laying idle so it did have one at one stage but i dont know when it disappeared.

    I'm hoping for a little more power as the pipes were badly fitted and not sealing on the intercooler which is where the oil was blowing out of, the pipe was pushed over the end-stop lugs and the hoseclip was tightened on top so only clamping on two points!
