Hey guys, I have a 2006 Mitsubishi Eclipse GT (3.8L v6 vtech) One day I was driving along and my engine just cut off; now noise or anything. I thought I was out of fuel so I filled it up and still nothing. My neighbor is actually a really good mechanic, so I had him look into it and he discovered that one cam jumped 7 teeth and the other jumped 2 and damaged some valves in the process (not sure how bad the damage is). I have a couple of questions.
1. Could I possibly just put it back in time and it run like normal?
2. He mentioned having to send off the head to have it machined. Is that really necessary? And what does that even mean?
3. Would replacing the valves and putting it back it time possibly fix it?
4. Is it all worth the effort or world it be a better idea to just replace the whole engine?

Hey guys, I have a 2006 Mitsubishi Eclipse GT (3.8L v6 vtech) One day I was driving along and my engine just cut off; now noise or anything.

1. Could I possibly just put it back in time and it run like normal? Anything is possible, but highly doubtful.
2. He mentioned having to send off the head to have it machined. Is that really necessary? And what does that even mean? All depends on what damaged occurred, bent valves, damaged valve seat, damaged valve seals head warp.
3. Would replacing the valves and putting it back it time possibly fix it? Again all depends on the extent of the damage, you may have cracked the top of a piston or worse.
4. Is it all worth the effort or world it be a better idea to just replace the whole engine? Only way to know is to open the motor and inspect the damage, then decide if the cost of repair(s) warrants it or a replacement.I think the best thing for you to do is to take the valve cover off, and remove the whole head, then inspect the damage yourself or even post pictures.
All the answers depend on how bad the damage is, etc. And i know mithsu loves to crowd engine bays so good luck.

I’m surprised no one has mentioned this yet: At the very least, you’re looking at replacing the timing belt and tensioners. Parts that are in good shape should not allow an engine to jump its timing.
If you have access to a good inspection camera, you could pull the plugs and take a good look at the pistons for any damage before you pull the head. If you have holes in the pistons, no need to pull the head, time for a new engine. You may also be able to look at the valves, although that is sometimes difficult.
