Is the Contour 2.0L DOHC have the same engine as the zx2 dohc escort? Both have #3 as 8th digit vin.
Link for example engine. Overhaul kits are the same for the two vehicles.
And why do some escorts have white valve covers and others black?
If that engine doesnt fit does any one know what model fits my 98 escort ZX2 DOHC 2.0?

Have you tried a parts interchange?
Some internal parts will. I figured they could be the exact same engine and still because of the different body sizes the external parts like ps pump alternator starters headers ect could all be different
Internal rebuild parts are the same though. This listing on eBay ( link bottom) says they are.
I figured guys on the forums would have a list of compatible engines and differences through the years.

The primary differences I'm aware of is that the early 98 has a superior thermostat housing (which will bolt to the newer engines and is a recommended upgrade for any zx2) and has the valve cover that has a bolt-on cover that covers the spark plug tubes and plug wires. I believe the whole valve cover is compatible with other ZX2s, but the newer valve covers do not have provisions for the bolts for the cover.

I think most of the differences are actually in the chassis and non-engine related wiring, I have a parts 01 in my garage and my early 98, but I do not have the engine from the 01.

couldn't tell ya honestly. never worked on many contours. I would assume that the block and head are the same there may be differences in the intake and other accessories bolted to the engine long block

There's a 99 I'm looking at . When I called the junk yard they said there's a difference between my 98 and the 99.
This thread this admin (pextor) says there is a difference in the way the engine is timed and a fuel rail plug but they can be retrofitted back . Do you know anything about this?

They look very similar. If I had more information I would use one as a viable option to replace my engine.

I have heard the timing peg supposedly does not get the engine to perfect TDC, but @schwinnman67 says he has never had an issue using the timing pegs on ZX2s and he has done many. If you are doing a belt on an engine that isn't broken and was timed correctly to begin with then you don't even have to worry about having the engine at TDC, just remove the old belt, install the new belt in the exact same place, replacing all the pulleys still of course.

Worst case you can just transfer everything from your old engine to the new junkyard engine that needs to be. The early 98 has a similar valve cover to the contour and I think the contours may have had same (better) thermostat housing, but I wouldn't guarantee they are the same. Also don't know if every contour had the VCT motor. Contour will definitely have different motor mounts. I believe between the focus and the zx2 (Other than the obvious lack of VCT and other stuff like having EGR) it was the timing cover that was different to facilitate the different engine mount on the front side of the engine (right side), but I haven't seen one close enough to tell for sure.

Is your engine actually blown or does it just have a blown head gasket?

Contour uses a different bellhousing setup, won't work. 98 to 99.5 zx2 engine uses 2 idler pulleys on the timing belt, while the 99.5 onward engine uses one idler and mounts it in a different position in the head. The 99.5 onward engines also have a different MAF hookup (3 wires vs 4 wires) and the AC wiring is different. I forget what the build date was that they made the changes, but if the 99 has the same number of wires in the MAF plug as your 98 then it should be identical for the fuel injection changes as well. You can look up the timing belt kits, they list one for 98 and early 99 with two idlers and a late 99 onward with one and they give the exact date of the changeover. I have done timing belts on 98 contours and 98 zx2s and they are identical inside, but the cars use completely different automatic and manual transmissions with different patterns

That's right I forgot about the idler pulleys on the timing for the early 98 (I barely even remember doing the timing at this point, it was one of the first things I did), but most (all?) timing kits come with sets for both, it's just important to not use the wrong/extra pulley, correct?

Cool thing about the 6 wire MAF is it is super easy to convert from a 4 wire to 6 wire MAF assuming you have the intake that doesn't have a provision for the external IAT. Of course you have to modify the harness slightly to do so. Wouldn't make a difference on the block though.

Either way I think that answers @Compoundcoaltrain 's question. I did not know the contour used a different bellhousing bolt pattern, I actually would have guessed they were were the same, they just use the MTX-75 which is not a direct bolt on in a zx2 and requires custom mounts.

Also, for clarification I wouldn't try to use a focus zetec in a zx2.

Ive found a 99 zx2 engine Im going to buy locally with low miles from the junk yard .
I spoke with an admin Pextor . He tells me even though the zetec engine timing setup changed over late 99 the long block will still plug right in my 98 chassis and trans, use all the sensors and what not in my 98 . I understand I may have to swap intakes for the iat sensor from my 98 and all I have to do if and when I do my timing belt is get components for a 2000. Im ok with that .
Thanks for the information on the contour . That's odd Ford would cast two different block for bell housings . Im happy I didnt look for an engine from a contour I would of been very unhappy.
Yes the focus blocks don't have vct solenoid so they won't work. I learned that early on.

Regarding timing issues, I had this problem for a year; and I use the timing pin. Timing is perfect and car runs fine yet threw a timing code. It was corrosion on the engine ground by the alternator changing resistance for the timing sensor.

Its just an oil separator baffle. Gives oil spray a chance to settle out of the air being pulled out of the engine by the PCV system and drain back into the engine. Since you can get to it would be a good idea to clean it out. Sludge can clog this over time. These are often located in the valve cover on other engines, just a different location for this item on these Zetec engines

the answer about the contour engine and the zx2 engine being the same:

  • the vct versions of the contour engine are interchangeable with the zx2
  • the brackets and water pump housing are vehicle specific so you will have to swap them
  • the oil pan assemblies are also specific, again, you will have to swap them
  • the exhaust is different, will need to be swapped
  • the contour uses different trans than the zx2 so the flywheel or flexplate from contour will have to be swapped to the zx2 unit
  • the oil separator for the pcv is specific, this will need to be swapped. The smaller contour unit can be used but would still swap
  • thermostat housings use different water neck. Cannot use in place of zx2 unit without corresponding zx2 specific water neck.

these are the main things about the contour engine when putting into a zx2. I've used many contour engines for swaps into many different zx2. Contour makes for a better donor because reasons

ps, you got wrong information about bellhousing. Bellhousing is part of trans and has nothing to do with the engine. The engine will bolt to the trans of zx2 and contour after swapping the oil pan assembly for each specific application

That will come in handy for the next guy thanks.

While I have all these zetec engine fans here what exhaust manifold is every one buying when they turbo their zx2s . I'll never turbo mine. I like turboing much bigger engines that usually run on oil but I am curious what ever one uses .
