Bonehead mechanic

Got this the other day,,,,E90 came in with check engine light on,,,,I could tell some kind of backyard mechanic has been working on this car and trying to fix the problem,,,,but they made the problem worse. The faults were lean mixture and airmass meter faults,,,,so I decided to smoke test the engine and found major leaks around the valve tropic motor and oil everywhere,,,,I removed the valvetronic motor and found it silconed in place with the whole gasket in 2 pieces and siliconed trying to seal it up with silicone,,,,,all they had to do is buy a new gasket and no more air leaks.

X6M bad news

   Ok this is bad news,,,X6 M engine came in not running good,,,,vanos issue on bank 1,,,,engine wasn’t taken care,,,the engine had a lot of oil leaks and coolant leaks,,,,valve stem seals leaking really bad,,,,also when you started the engine you would hear a load rattle noise coming from the engine like a chain rattle noise,,,,the noise would come and go,,,,well bad news is the right side timing chain rail broke and caused the timing chain to jump timing causing the valves to hit the Pistons and bend and break causing major damage.
