Hi all
Really hope some one can help me out there as Porsche are trying to avoid a warranty claim.
My wife has a 2014 Macan Turbo with 36,000 miles on the clock. It has extended warranty and all servicing has been completed by Porsche. Last month the engine started making a knocking noise and so we got it collected to our local Porsche centre.
They have ended up stripping the engine to investigate and they found it has water mixed in with the oil and they are blaming that for the damage to one of the cylinders. The water is not from the coolent system (been tested for glycol) and so it has to have come from someware else. Water has not been put into the oil filler and whilst the car has been driven in wet road conditions, it has not been in water other than shallow puddles which occur on the motorway. The air filters are completely clean and intact and so we don't think water has entered though the front grill system of the car.
Can any one think how else water could have got into the engine? They advised me today that 17% of the oil volume is water.
The damage to the engine is cylinder no 2(middleone of left bank) which has completely worn away the lining and the ally and a slight dulling of the cylinders either side, the right hand bank are all perfect with no wear at all.
Could the cylinder damage on no 2 cause a build up of water in the engine from condensation or anything else?
When the oil filter cover was removed from the engine the oil was milky in colour indicating it had emulsified, however after about a week of the drained oil sitting in a bucket it has gone back to a normal oil colour but with metal glitter evident in it. No signs of of emulsification at all- does oil separate back into water and oil once its mixed?
Any help or advice would be appreciated as at the moment they are expecting us to pay for a complete new engine?
Thanks all
