dc89 Posted April 13, 2012 Share Posted April 13, 2012 Hi im new to this forum, i have a problem with my 300tdi discovery, yesterday i drove it about 6 miles no faults or issues. Then left it for around two hours then started it up and oil warning light came on. I drove it about two miles but still kept on with a funny popping sounds at random intervals. pulled up took the oil filler cap off and smoke came out of there. it is also majorly underpowered now so am at a complete loss hope someone can help. cheers dale Quote Link to comment Share on other sites More sharing options...
ballcock Posted April 13, 2012 Share Posted April 13, 2012 Do you checked the oil level regularly? Have you got any large leaks? Can you trace the poppping head or exhaust etc.? Quote Link to comment Share on other sites More sharing options...
dc89 Posted April 13, 2012 Author Share Posted April 13, 2012 i check quite frequently, there seems to be no visible major leaks however took the intercooler hoses and intercooler out and found there coated in oil Quote Link to comment Share on other sites More sharing options...
dc89 Posted April 13, 2012 Author Share Posted April 13, 2012 found the cause of the noise its something hitting the inside of the turbo so think thats seen better days, however would this cause the oil warning light to come on Quote Link to comment Share on other sites More sharing options...
BogMonster Posted April 13, 2012 Share Posted April 13, 2012 The turbo might have seized I guess. Take the hose off and see how much play there is in the impeller, or whether there are obvious signs of distress like half the blades or big chunks of the impeller housing missing...

dc89 Posted April 14, 2012 Author Share Posted April 14, 2012 took the turbo off today, lots of play on the spindle, however im unsure if replacing the turbo will solve the oil warning light issue Quote Link to comment Share on other sites More sharing options...
p76rangie Posted April 15, 2012 Share Posted April 15, 2012 Turbo is lubricated by engine oil. Stuffed shaft allowing oil past into air intake, therefore using oil. You should not drive it as the motor can actually run on the oil that is escaping. If it does it will not stop running until all the oil is used and the motor is completely knackered.

They go like stink though, until the conrods come through the bonnet Quote Link to comment Share on other sites More sharing options...
dc89 Posted April 22, 2012 Author Share Posted April 22, 2012 right an update replaced the turbo with a good second hand unit no play in the shaft however oil warning light still remains on, still burning oil and smoke coming from oil filler cap it is very difficult to turn over and sounds like its almost seized really unsure what could cause it Quote Link to comment Share on other sites More sharing options...
discomikey Posted April 22, 2012 Share Posted April 22, 2012 take injectors out all cylinders, and then turn engine. it should be quite easy to turn with a breaker bar or ratchet on the crank. if not its probably siezing and on its way out. smoke coming out of filler cap, i think you mean its breathing heavy, which is probably buggered piston rings or headgasket. id think about taking the head off, having a good look inside the engine and inspecting all the bores for any scratches or scoring. in general if you can feel it on your finger, youll need a rebore., and probably do the rings/bottom end bearings too as it cant do any harm.

Marten Posted April 27, 2012 Share Posted April 27, 2012 Maybe you are well into an engine strip by now but, if not, I would seriously consider it. Whilst the oil pump and associated drive are robust and generally reliable, it seems a possibility that you are not achieving oil pressure within the engine, despite plenty of oil in the sump. This could have starved your turbo and be causing partial (soon to be total) seizure of the pistons & bearings. You haven't mentioned engine coolant temperature! Did you notice a rise in engine temperature? It's just possible that the engine oil strainer and suction pipe assembly has detatched from the oil pump body and is laying in the bottom of the sump.
