I need to ammend this. The 20% seems the likely number for RMS failure not IMS failure (which is indeed usually more serious).
IMS failure rate is much lower, but still higher than one would expect for a 'normal' reject rate for a manufactured engine.
There can be catastrophic RMS failures which kill the motor, but these are pretty rare. RMS usually develops as a slow drip which increases. The big issue with RMS is the extent and expense of fixing it (with no guarantee the fix will work).
IMS on the other hand almost always takes the engine with it.
