I have the cross over exhaust on my +8 which makes putting the sump back on and keeping the gasket in place fiddly, the removal is quite straight forward. I used the cork gasket and put dabs of exhaust gasket sealer around each nut hole on the sump to hold the gasket in place whilst matching it to the block. Make sure you tighten the nuts evenly and don't over torque, Oil sump to cylinder block 8 lbf/lb and the rear bolts 17 lbf/lb.
