I tried to be careful with the feel of it. Snug but not pushing it. Used a screwdriver handled wrench so as not to get over-assisted leverage on the screws.

Had a head crack on mine - no obvious sign bar the odd plume of white smoke on changing gear, shut down ASAP. AT that stage coolant level had dropped - no obvious intermix showing on dipstick, presumably as stopped ASAP.

So from what you have described I would guess not, certainly hope it's cheaper for you!
