Replacing a head (SR5 V6)
I am looking at a 4 runner on EBAY that I am assuming spun a cam bearing as the owner says it needs a new head, something to do with the cam. Now I haven't researched much yet and this would be my first non-american rig. But I am wondering; Are these things dual over cam engines? Also should I get this truck what else should I be looking at? It seems to me that if it spun a bearing either it was run without oil or there was an oil flow issue. So should I be checking oil passages? Go ahead and replace the oil pump while I'm in there? Just curious.
