Contour Enthusiasts Group Archives Forums Modifications 3.0L Duratec Starting from scratch

I now evidently have a bad 2.5L and 3.0L motor. I don't have the enthusiasm for trying this again. What are my options on a built motor?

I hate to hear that. They are bad in what way? Did you pull the heads and see for yourself?

If the valves have hit the pistons but didn't break then you will probably need new valves, but the pistons may be fine. If the lower end of the 3L is good, then take the valves from the 3.0 and have them installed in the 2.5L heads. It will only cost you for the exhauast valve seats and a complete valve job. Then you could salvage the whole project.

Merry Christmas to everyone.

Definitely going to take the top end off and take a look, but just going by what Bankston says. They attributed the sound to "piston slap". Never actually heard piston slap before, but it sounds more like a rod to me. I may try to get a video complete with audio and post it for everyone to hear. As I said in my first post on this forum, I don't have a clue. I do know I went out of my way to keep from putting any stress on the 3.0L crank as it was being put together. We'll see. Thanks for the suggestions.
