When I purchased the car Jeremy told me it had a blown head gasket. I convinced him to help me rebuild the engine. He always been great to me and allowed me to come over to the shop after hours and help him with removal, assembly and installation. In the end he did most of the work as I watched and got in the way here and there. I did learn a lot.

Once we got the engine out and removed the head we noticed the head gasket was indeed fine! Turns out one of the valves was slightly bent. Ouch! He ordered the parts and we proceeded to rebuild it! We Rebuilt engine on 8/25/01
