Well there what looks like oil or water all down the block and the coolant looks very oily. May as well just accept head gaskets gone(thought the power was down recently as well). SOooooooo CVH 1.6i head gaskets. Exhaust manifold off, inlet manifold off, rocker off, then what,lol. What do i need to get other than the new gaskets? is it easy-ish to do?

just a quick second thought, all the water/oil on the block is round the same height at the water pump/head to bottom end joint. now the water pump was replaced recently. Say it is that leaking(the gasket) would it cause a lack in power?
it wud explain where the coolants going and due to oil being around the block it could have sucked some in, but would it lose SOME and i mean about 10mph in top end power?
