The timing chain on my rebuilt Datsun 280Z broke and I’m not sure of the best way to rebuild the engine. When the chain let loose the exhaust spit out a combination of oil and coolant so obviously there are many issues to resolve. I tore the engine down and I currently have the head off and the block still mounted. So my question is really about the best way to approach rebuilding the engine. I’m guessing the head might be cracked but I don’t know if the block may have also been damaged. Can anyone help give typical repercussions of losing a timing chain and the best course of action to start rebuilding the engine? I’d like to avoid spending a lot of time and money figuring out what needs to be replaced so any information would be great.
