My employer had just set up a deal with a local auto repair shop that I tried out for my 2000 S80 T6. During the inspection they noted leaking turbo seals which I had them repair along with a 115K mile service. No sooner than I pulled off the lot the check engine light came on. I returned a day later and was then told that the alternator and battery needed replaced. I had that service done then while driving home that evening, the engine oil seal / plug on the top of the engine blew out. I'm now told it was all a big coincidence and that the breather box, pvc was likely clogged and by repairing the turbo seals, the engine pressure built up and blew. I'm not sure I believe it all and would like some help here before I make my next decision.
