I've turned it over by hand and it seemed fine. Then when I checked my camera, low and behold the recovery scrotes have started it and moved it 3 times at the recovery yard. Even when the RAC key tag said "does not run." The first time I can hear one say to another. "Doesn't start. My arse!"
They could have done more damage as when I got it back, the oil was just below the actual dipstick.
Admittedly there's some air flow, but there is when I try to suck up rivet ends with my Henry in the workshop, and they don't easily carry up the hose.
What I'm saying is I reckon most bits will end up in a pool of oil in the bottom of the intercooler, rather than ever make it up hill to the inlet manifold.
