I have a 86 truck with a coolent leak but cant find the leak every three days or so i have to fill up the radiator. Theres no visual leak no drips it magicly dissapears the oil cap is clean any advice

 

blown head gasket ? maybe its just burning it and not collecting it in the oil.. check oil for water though

 

I have i look at the oil level every day and its gold color not like milky the back on the head is moist can i be the pips the go back there

 

i'm thinking BHG

 

Do you smell antifreeze inside the truck?

Is your floor/carpet getting wet around the front of the tranny tunnel?

Are there ANY wet spots under your truck after it's been parked for 15 minutes or so (anything longer and you might not see them, water can evaporate pretty quick)?

Does it smoke at all? If so, what color (white, blue-ish, black)?


I wouldn't think it'd be the pipes on the back of the head, that's all emissions stuff IIRC.
