A couple weeks ago my Nissan Quest overheated blew the radiator cap off. Replace the lower and upper radiator hose, change the thermostat but now there's smoke coming from behind the engine and a resistance in the accelerator.
There seems to be oil leaking from somewhere but we can't figure it out. There is oil in our spark plugs. I check the oil. It looks dirty but it's not a chocolate milk substance, so I don't think we blew a head gasket.
I have no idea what's wrong.
