Oil filters either come with a bypass valve or they don't - The bypass valve is there in case the pressure differential (Between the incoming and the outgoing oil) in the filter gets so high, possibly because of debris blocking the filter, that some oil, dirty as it may be, will still get to the engine. This is not A Good Thing for performance engines. At high revs, it's possible to get so much oil flow that the bypass valve will open anyway and so the oil is not being filtered! If you take the time, it is possible to get a filter for your engine that doesn't have a bypass valve. The only thing you must be careful of is to take great care in warming up the engine before running it at high revs. (It takes me at least 15 minutes on an average day to warm the engine before I'll rev it hard)
Putting two and two together here, and I'm probably getting at least 5, and this has probably been discussed long and hard before, but anyone care to comment about the quote and big end no.3?
The rest of the site wasn't bad either - but then I know very little about engines. I'm learning though

Nearly all modern cars use a bypass filter. Is anyone really going to leave a filter in their car long enough for it to actually clog up, and allow any dirt that MAY be in the engine to do any damage. A worst case scenario, that seen the filter clog up, would just allow the ( possibly slighlty ) dirty oil to bypass it, so there would still be oil flowing were it needs to.
The engine failures are not from dirty oil, the big ends etc seem to go due to a simple lack of oil flowing to them, for reasons which just arent too clear.
Probably one fo the first things to go, if the oil was dirty would be the turbocharger, most other areas of the engine are pretty robust, and can withstand a lot of things, the turbocharger is not so robust when it comes to dirt.

T'was just an idea
Will keep thinking - there must be some reason(s) behind the failures.
Clutching at straws is OK, as long as you can let them go fast enough...
