Hello,first i want to apologise for my bad english.
After my bmw started eat some oil, we decided to change valves seals, everything went smoothly, we time valves without the tool. After that my bmw started fine, but engine havent all power.
So we decided to try time valves one more time. After that, my car started and at once engine stopped. Tried to start one more time, but it failed. Then i connected INPA, and it displayed 4 engine faults:
after we tried to set timing some times more, but every time we getting same faults
Then i delete them, engine starts, but after several seconds all fauls returns, and EML lights up.
Two engine fixers, said that timing is set correctly, and no one do not know what can be.
What we are doing wrong? Can chain be worn?
