Long story short, my 2016 EcoDiesel was in a respected local shop with multiple locations for 4 months with a bad glow plug. After trying and failing multiple times to extricate the plug, I ended up approving them to replace both heads and all the plugs. On their test drive, there was a massive oil leak inside the bell housing of the transmission where the rear crank seal and crankshaft position sensor are. The crankshaft apparently blew in the process. I previously had the tone ring break on me in 2019 and the truck was repaired under warranty by a dealer (about 80,000 miles ago). The shop is telling me it appears there were pieces of the old tone ring in the transmission and they’re saying this caused the oil leak and it was just bad luck that it happened right after the replaced the heads.
I’m not a mechanic so I don’t know if any of this makes sense. Are they just guessing that I’ve had the tone ring replaced since that’s a known issue with this truck? It seems highly suspicious that they’ve had my truck for 5 months and the motor happens to blow up the first time it has been driven after they have done some thing heavy work on the engine.
