Fixing a Blown Out and Stripped Spark Plug with a TimeSert Thread Insert on my BMW

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.

That's crazy. My 2 cylinder is the one that melted and 5 is the one that stripped it's threads, same as you.

was that 323 ever in some sort of collision repair? bmws usually have some sort of sticker on driver side strut tower, but mine which is early 00 model does not have, hope this is a thing for 98, 99 and early 00 models, ngl drivers side looks unusualy dirty to be that covered up with dust and soot, maybe structure which holds fender was replaced at some point if seam sealer shows traces of rust and paint flaking...

So is this the only other option besides drilling it? It’s a $200 kit, there’s other $40 kits which I’m guessing don’t work with the M54?

Hey by any chance would you be willing to rent/sell this tool out? I fix one of my spark plugs on my E53 m62tu after doing a valve cover job lol
