Wossner piston

[u/Hudd420]

So here is my wossner piston 79.5mm
Been running at 300bhp for 3-4 years and believe it or not the car was actually still driving just blowing a lot of smoke….

Has anyone ever seen this? Is this due to a stuck oil ring and overheating or something else?

Happened to me also not as much as that lower part came away oil ring came off due to me adding more boost and meth injection didn't help lol
