Re: The BMW N42 fails to start subsequent to the replacement of the valve seals.
Ultimately, it started with arid cylinders. I added two teaspoons of oil to the cylinders, resulting in a tripling of the compression. Three weeks of conflict, believing the task was inadequately executed, ultimately revealed it to be an unrelated problem to the repair. Gratitude to all

Re: The BMW N42 fails to start subsequent to the replacement of the valve seals.
Upon examining the matter, I believe the most probable culprit at startup may be the valve lifts. I removed them during the task, and they remained in a horizontal position for a day and a half with the drain hole facing upwards. Some may have leaked, resulting in a loss of fluid, allowing air to en...

Re: The BMW N42 fails to start subsequent to the replacement of the valve seals.
Indeed, with the curved section oriented upwards—there was an instance when it was positioned downwards—the timing is optimal, and the tools fit seamlessly without exertion, resulting in a tiny deflection of the exhaust shaft. It is evident that either the cylinder head is warped, which appears impl...

Re: The BMW N42 fails to start subsequent to the replacement of the valve seals.
Executing this procedure without elevating the cylinder head by threading a string through the spark plug aperture obscures the view of the valve seat. It is peculiar that several others have used this method without encountering issues, nevertheless all of my valves are inadequately seated.

Negative. This tool will not distort a cylinder head.
Have you verified your valve clearance?

Re: The BMW N42 fails to start subsequent to the replacement of the valve seals.
Do you believe it is feasible to distort the cylinder head using the valve spring compressor tool?

The BMW N42 fails to start subsequent to the replacement of the valve seals.
I replaced the seals without detaching the cylinder head, using the rope technique and a universal lever tool. The vehicle fails to start; it attempts to engage but does not succeed. A spark is there, accompanied by the odor of gasoline, and the timing is appropriate as all tools are compatible. The...
