Thanks for your sign off Tin. Appreciate your regards. Just followed the POH from memory - especially the expanded section - sometimes an area worth reading since it came from those in the know so to speak and didnt have a lot of time to check my notes when it happened. dunno about the ten minutes as i was keen to get a feathered prop - didnt get to the bar that night to hear that gem - and was also outbound and not intending at the time to come home - anyway got to see the red warning light and watched an oil psi needle falling quicker than the ozzy dollar past 38 psi plus a torque gauge and shadin reading going ape - and the rest is history - knicked the edge of the road (bitumen to gravel probably hurt the tyre) just waiting now for the parking ticket. Flying it home the next day was more stressfull. Problem PROBABLY appears to be a broken seal at the cracked and separated forward elbow lug of the oil supply line to the prop and reduction gear box (see Flight safety trainining manual diag page 6-9). My thanks to the firies and controllers as they were excellent in their assistance (and i apologise if i forgot to readback anything at the time)
