Have Ford Questions? Ask a Mechanic for Answers ASAP
Hello and thanks for your question. My name is ***** ***** I will do all I can to help.
It sounds as if the timing chain could have slipped to me. Especially if it is a 4.0L. With no compression on one cylinder and another one affected as well, it's definitely internal engine if what they are telling you is 100% accurate. The 4.0L's were bad to throw a timing chain and cause compression loss. It's possible maybe the harmonic balancer came apart or came off the front of the engine and caused that major violent shaking, but that still doesn't explain the compression loss, I would also make sure it was full of oil and for some reason the engine didn't lose all oil pressure previously to having this problem.
I would ask them if they thought it was a timing chain, an oil pressure issue, or if the harmonic balancer came apart or failed in any way. As far as putting an engine in it, it depends on if you really want to keep it or not and if there were no problems with the truck before this. If it's in great shape, and this shop can give you a fair price on a replacement engine I may fix it. As if you trade it you will likely not get a good trade in price with the condition it is in now, please let me know if you have any further questions. Thank you.
