My 1999 BMW 323i blew a spark plug out of the aluminum cylinder head and stripped the threads. Can it be saved? In this video, we use the TIMESERT 4412E-111 kit to repair the M52TU engine. Then we perform a compression test to verify engine health before installing new spark plugs. This should apply to the M50, M52, M54, and other engines.

This video is not sponsored. I purchased the Timesert kit with my own money and decided on it over Helicoil and save-a-thread as they seem to have a better success rate, however I have not used the others for comparison.
