what is the deal with the sohc engine that they cost so much more than the dohc were there just not that many made? I cant decide what to do with mine should i rebuild it or get a used sohc or do the swap to a dohc i cant decide anyone have a preferance.

The reason that an SPI motor is so expensive is that the valve seat drops, mainly in cylinder four, and grenaded all of them. It was a design flaw. So, any of them that are left are rare things and more money.

I would say that if your motor isn't totally trashed it could be worth rebuilding, but if it is all scored up or anything like that then you might want to think about going for a more reliable, less expensive Zetec. Even better is if you can get your hands on a good SVT motor.

If you really want to get into something big then you could look at swapping in something like the Contour V6.

thanks that is what i was thinking they were rare thats why the cost is so much. my crank was scared up pretty bad and it knocked a hole in the oil pan so it would be a major overhaul so i think i will look for another route maybe a swap out for a dohc. what all is needed to change over for one of those?

I just did a swap with the same vehicle. The car runs great and i only ended up spend about 600 for the total swap out. The hard part is changing everything else thats wrong...lol.
