so i am helping a friend do headgaskest on his 2.2l turbo and was wondering what should we replace while it is out? what seals, water pump? i know we are doing valve cover seals, rear main and timing belt but what else do you sugest, thanks.

oh also, there is not much oil residue on the motor so i dont think it is leaking much.

Rear cam o ring would be a good idea, replace the hoses going to the turbo and near the turbo.
