got my car yesterday 94 Honda Civic. Think it needs a head gasket or valve seals or whatever the guy said it needs a head gasket. There’s sludge everywhere on the bottomside of the engine area When you turn it on it has a lot of white smoke clouds of smoke from the exhaust it also isles up and down a lot I think it needs a distributor or alternator too because after you jump the car it dies right after you turn it off and doesn’t turn back on. Also needs a driver caliper He said. The brake pedal goes all the way down the ground but doesn’t stop the car good at all I had to use the e brake and he said I gotta keep putting in brake fluid. The oil isnt orange or milky the cap is clean I have to change the oil because it’s dirty and add more coolant. Any idea what it could Be ? Here’s a video link https://youtu.be/1K3B2Vc2-yA
