i have recently purchased a 1990 nissian 240 sx

this is why im here

my car seams to be leaking a oil/antifreeze mixture it seems to be coming from the head gasket but it cant be sure.

does this seem right due to the mixture?

intermix is bad, especially if its leaking. Don't run it anymore, your need to replace the headgasket and you should get the head checked / milled if needed by a machine shop.

Drain your oil, see if its green in color or milky looking or smells sweet. Was the exhaust steaming or smoking?

Drain the oil its hard to tell on the dip stick. If it looks like chocolate milk or visibly its intermix. Either from a warped head, blown head gasket, or cracked block.

Ok see post two. Pull the head, check decking, have the head checked and milled if needed (60 bucks), replace head gasket, timing chain and gears if you can afford to.
