a reliable 3.0 with a bad head gasket?
I'd want to open it up and see what other damage is done before I'd even be willing to put a price on it. THose engines will self destrcut quick when the head gasket blows.
Toyota was going as far as replacing short blockd , sometimes full on rebuilds due to the headgasket issue. many never really had much problem until you looked inside.
$50 rebuildable boat anchor ?
