RST 1.9, T3 turbo, not run hard untill hot, left to cool down slowly, 4000miles only from a company that advertise large engine for small, and never really been happy with it, did a compression test at the weekend, 120, 118, 22, 50, so something was not right, took the head off tonight, 1 bore scored, no detonation marks, took the engine out and found this,

all the rest of the rings were broken in 2 or 3 pieces,
Now Ive seen broken rings, but never like this.
Any Ideas why????
