is the oil pan gasket hard to replace

 

Not really, but it's messy as hell. There are about 18 small bolts and nuts holding the oil pan. You may have to remove the flywheel cover to get at the bolts on the transmission side.

When you install the gasket, make sure you apply liquid gasket (Honda P/N 08718-0001) at the sharp angle points. Then Honda recommends installing the bolts/nuts starting at the front center and back center of the oil pan,alternating front and back, and alternating left and right, working towards the transmission and crank pulley. The manual has the correct sequence.
