That wouldn't allow pressure to build in the crankcase though mate, has to be piston/bore related, ie hole in piston or rings stuck in grooves maybe.

Techy help required please. (Non Zed related)

I'm Inclined to agree Dave but Jue is still wanting to keep it if it's not going to cost a fortune to repair. Will see what the neighbour says when he's home tonight. Maybe you should have a word with her being her dad and all that!!
Whichever way I read that Tony it just spells Money
If Jue likes the style and room, get shot of that one for another. Easy
if your neighbour has a compression tester, its not a huge job to identify which cylinder the problem is on, well, injectors out again.
If he has an endoscope that will fit down the injector hole he can get a visual on the problem without striping down.
If its a holed piston, it'll certainly sound something serious as soon as you run it! I'd expect it to smoke as well as oil gets ejected out into the exhaust via the duff cylinder.
I'd doubt if a single stuck ring would cause enough of a leak to pop a dipstick, I'd expect a crackcase breather to disperse what little pressure that would create, assuming the breather is clear. Unlikely to be multiple stuck rings unless the piston has started to melt.
but I could be very wrong.

blue/grey smoke is probably oil going up past or through the piston and being burnt in the exhaust manifold. Either way, its looking like a piston.
Sorry bud, its looking expensive.
IF you can get the sump off with the engine still in the car, you MIGHT get way with honing the bore and replacing the piston & rings without lifting the engine out. Obviously the head has to come off. And it'll be a right "b1tch" doing it in a driveway.
ps, don't run it.

Why thanks for the happy news lol!!! Yep we been told not to run it. I'll see what the neighbour says later today and we will make the decision.
I've now spoken to my neighbour. He hasn't got a compression tester so that's not been done. He has re-seated all the injectors using new brass washers and he's very happy with the one that had to be heli coiled. He took it for a test drive and was very impressed with the power it gave in comparison to his 140bhp model. He then said it started to smell of oil so pulled over to find the dipstick out and oil all over the engine compartment. He limped it back and did further investigations finding oil in the turbo to intercooler pipe saying again it's down to pressure in the crankcase. All the crankcase breather is clear. So that is where we are at. No definite answer as to the problem but he says it is definitely not injector or turbo related. HELP!!!! @Lee?
For it to push the dipstick out and blow oil all over it has to be pressurising the crankcase. Only thing I can see causing that is blow by of a piston, either one has a hole or it's losing it down past the rings at the side of a piston, unless the oil level is WAY too high?
Tony.
Oil level was fine Tony prior to the blow out. Could it be the pcv valve? Just reading online trying to eliminate things.
PCV?
Tony.
Tony.
Positive crankcase ventilation valve mate
Managed to borrow a compression tester and code reader, I'm fetching them Sunday afternoon so my neighbour will do the test early next week.
I would go with your crank case vent being blocked mate. Should be a PCV valve there that separates the vacuum and oil, if it cant do it job the oil will either start burn going through the inlet manifold or blow out somewhere like the dipstick.
Edit: Then if its not the PCV it will be a stuck ring/worn

Part of the breathing system then, I hate all these abbreviations. Is it electrically operated? If it's just a plain old valve with a posh name it may be possible to remove it temporarily, to see if it reduces the oil blow out or clean it?
Tony.
Mate your way ahead of me here! I haven't a clue what anyone is going on about! Just passing on things as I come across it from various angles.
I think it has mate to be honest. Car hasn't been right since we bought it. We've had it 6 months, I think it's just finally come to a head.
