After 2 years of rebuilding my fj62, last night while driving back home it started to just shake bad. luckily it all happen when I was a couple blocks from home. After parking it all the thick white smoke coming out of tail pipe. So that usually intels head gaskets or cracked engine block or head. Will see when it gets fully inspected. But if it needs a whole new engine I don’t think I will dump money like anymore. I will part it out at that point.
