I'm having a major problem with your 2 posts. While I understand your choice to go with new vs repair old engine, I would be surprised if you could get a new complete engine installed for $5000. Did you just get a new short block with the old cylinder head? A new head gasket and labour should not cost $4500. If you did not get a complete new engine, block and cylinder head then I could see an underlying issue causing the head gasket to blow again. These engines are not known for head gasket issues or major engine issues in general.They didn't. They just said it blew again. My brother is a mechanic. He said there had to be underlying issues with the wngine to lead to a head gasket blowing
