Yeah, same sort of quantity, I couldn't believe it when I pulled the hose off, thought I'd pulled the sump plug!
Those 3 bolts go from the gearbox side into the block, prob about 5" long. A spanner does go on quite easily, it's just difficult to get any force on it while laying on your back with the sump an inch from your nose! If you could do it on a ramp it would be loads easier.
The starter motor also needs to come off, even thou when you look at it it looks like it can stay, but one of the bolts goes into the block.
Just hope I can get the clutch aligned easily with my alignment tool and get it back in as easily as it came out.
If you only need to do cam belt and water pump, access at the front is very good when you remove the rad, condenser and crash bar as a complete assembly, only took me an hour to get to that stage as well.
