A friend of mine has a B2000 Mazda truck and today we came back home to my house and it started smoking really bad. It still ran fine but we turned it off as soon as we got here and looked under the hood and it seemed to be comming out around the exhaust manifold, well it looked like it but could be comming out from somewhere else so not too sure. Does anyone know what it can be besides not having enough oil? Any help would be appreciated.
Thanks.
