Ok.. Bought a cheap focus for my step daughter last night. Does not start so I got it cheap. Is very straight and pretty clean and everything seems to work on the car other than the engine. I am a pretty competent shade tree mechanic. Been wrenching on my own cars for 20 plus years so digging into or replacing the engine doesnt scare me. It cranked but sounded like it was cranking sluggish and when it did fire it sounded pretty bad and died agian. So my question is this. If I end up having to replace this engine, what years are compatible? What bolts right in and goes. Or what short blocks bolt in if It is just a thrown rod or something? I dont mind putting this head on another engine and all the toppings if I need to. Any info would be helpful. This Focus is a 2.0L SE automatic with the base single cam engine in it. Also is there anything else I should check on these such as regular problem areas?

Yep. That is the single cam motor in mine. I wasnt sure how it was referenced but SPI makes sense.

Would rather just do a straight swap if I need to swap it. Its for a teenage girls first car and its a automatic anyway so no point in trying to make it faster. Just need it to go and go safely and reliably. What years had this exact motor?

Its the SPI motor, and I do know the general history. Looking more for someone that knows what cross references. Like did they change any sensors in certain years that make the swap more difficult? Do they all have the same flywheel bolt pattern? Is the Duratec 2.0L short block a direct swap for the SPI short block? Did the SPI engine come in another vehicle that would also swap into this car. I think I have seen them in escorts at the salvage yard before. I am looking for specific information. I understand I can search the site and get information on the engine I have. I want to know about the engines I dont have or may need to buy.

Ok.. Forget the Duratec. I figured out it is the masda 2.0L and has more in common with the zetec. So just looking for SPI cross reference. Figured out it is in the 97-02 Escort and 97-99 Tracer but not sure if those two are direct swaps or not.

Thanks.. That is kind of what I am looking for. Looks like that answers my question too about the escort. The head on it is totally different too. So basically I need to find focus parts only.

Moved to the SPI section where you'll find the most info.

Thanks.. I thought that is where I had posted it.

I did get it torn down a bit today. Head isnt off yet but I did do a compression check and
#1 - 150
#2 - 160
#3 - 160
#4 - 0

Pretty sure I definitely dropped the valve seat. So no worries. Digging in.

Any dings to the #4 plug?

That usually shows if the dropped seat happened.

The electrode was bent pretty bad but the plug really wasn't that bad off otherwise. I will know more when I get the head off but i am thinking it may have been shut off quickly. Looking through the spark plug hole the piston looks ok but I can't see it that well either.

If you go deeper make sure you clean the intake manifold out good, the small pieces can back aspirate to go into intake and into other cylinders after a repair to tear up engine all over again.

Yep. I may even replace the #4 piston depending on what I find when I get head off. Will plan on having it off one day this week after work. I found one place at $250 for a reman head. Anyone know somewhere better?
