Silber’s 2002 Boxster S Engine Build

[Silber]

Broken Valve Spring.

I guess the moral of the story is if I hadn’t keep running the car after it stopped putting out power, I might’ve gotten away with just a valve spring. Since I kept running the car until I heard expensive noises now it’s a rebuild. Maybe there’s a lesson in that I don’t know LOL

Edit: Kept going with the tear down and got the 1-3 head off. As expected there were three valves broken off, the head was kind of munched, Cylinder walls were cracked, and there was a small chunk missing out of the bearing carrier. now I have to try to source one of those.Got a lead though we’ll see what happens.

If cylinder walls are cracked, this isn't a rebuild any longer...

I have a spare block and wasn’t really planning on using this one anyway, however when LN sleeves the block they machine out the entirety of the cylinder walls, and replace them, so cracks may not have disqualified it.
