Once the cover is off, you'll need to be wary of a noticeable gravitational effect. "Gravity holes" are the effect whereby a "hole" generates a gravitational field. The smaller and deeper the hole, the greater the field. Black holes are an example of this. The Stag engine generates gravitational fields in many places, such as under the inlet manifold, but one of the worst is the hole where the sump sticks out from the block when the timing chain cover is removed. If a free falling object gets anywhere vaguely near this hole, the gravity field will suck it straight in. I recently re-adjusted my chain tensioners and took *great* care to always fill that hole with an old shirt, and even then, the one time I forgot, I dropped a bolt. This is where another well known effect also comes into play. The gravity field generated by the hole can, in severe cases, actually distort space time. This is noticeable when a falling object enters the field, time can be observed to slow down. You can casually watch the falling object as it is sucked towards the hole. Gravity holes differ from black holes in another area. Where a black hole is commonly understood to distort space such that light cannot escape, a gravity hole lets light escape but prevents any non-falling object from entering. This means that you can often see an object in a gravity hole, but can never reach it. Strange but true. If for example, you put a straight piece of wire into a gravity hole, because space is distorted, you can never reach the object at the bottom of the hole. Of course, if the wire becomes free falling, it goes straight in. When this happened to me, I was very lucky in that the bolt hit the sump, bounced up... and fell outwards. I have, in the past, helped someone else who wasn't so lucky. By lifting the engine slightly (gearbox bell housing permitting), lowering the sump, poking wire through the drain hole, and muggins here sticking his arm between the sump and the block (something that scares me now, but I was young and foolish at the time), we managed to get a nut out of the sump. Of course, you could just leave anything that falls into the sump where it is - and if that happens, believe me, leaving it there will become an annoyingly attractive option.
