I have a very small antifreeze leak dripping down the driver's side of the engine onto the exhaust. I am assuming i have a bad head gasket. I also have a small amount of oil appearing under the radiator cap. Sound like a cracked head to those who have dealt with this?

I also have lifter tap on cylinder 3 and/or 4. brearings sound good per the broom handle.

I have replaced radiator, water pump, tstat, hoses. also replaced, coil pack, plugs, oil/filter, air filter in attempt to cure rough idle but still persists. the only code thrown was cylinder 5 so going to replace all injectors.... Replaced oil sending unit so now oil pressure is 20psi at warm idle, was 0.

any words of advise besides clearwater or alabama cylinder?

Can anyone rate difficulty of replacing the head myself? Need instrucitons please

is there a doctor in the house???
