You may have heard of cylinder bore scoring as it relates to the Porsche 911, Boxster, or Cayman built for the 1999-2008 model years, but chances are you don’t know the full story. In this final of four videos, we discuss your options to fix bore scoring if you can’t live with it anymore or it’s gotten to the point where it needs to be fixed. Unfortunately, there is no cheap option here, but you do have a couple options if you want to do it right. In addition to the right ways, we also cover several examples of the wrong way to fix bore scoring in these engines and how these engines end up failing again.

Great series!! I’ve been watching as many videos as I can and been reading forums posts for years about this topic and still learned a ton. Glad it’s all in one place to reference for everyone. I really appreciate what Charles, Lake and the like have done for the community. When my time come, hopefully this route is an option for me.
Engineering at is finest than will force you to buy a new car every 100k
I assume the 3.4 from Cayman S can also be bored to 4.0, right ?
Lots of great info…
Great series!
Is there a list of recommended shops for rebuilds, etc. that PCA can point us to?
