few sohc build questions

I posted in general tech section but got nowhere so now im trying here. I'm not familiar with the focus but far from new to cars in general.

Just picked up an extremely clean 2001 automatic se sedan with 112,000 miles and an engine with 4 destroyed pistons, 2 broken rods, 2 severely bent rods, a bent crank, destroyed block and destroyed head. Probably the worst valve seat explosion ever.

My plan: Build a new block and buy the ebay head with better valve guides and seals and let my girl drive it over as many curbs as her heart desires while getting the best fuel economy as possible.

My questions: I have access to every block that came in the focus and escort at my local junkyard. Which block would best mate to the sohc head for fuel economy with little to no modifications? Who makes the best gasket kit for this build? Anyone have experience with these ebay heads that claim they have upgraded valve guides/seals? any tips to get better fuel economy out of the engine while I'm building it from the crank to cam?

I'm not interested in swapping harness' and computers, door locks, ignitions and keys so I'm staying with the single cam head. No way around that one.


Thanks in advance for any help, tips or info.

Just get a focus block (but good luck finding one thats not had the valve seat issue), the escort block is slightly different in some cases. I use Eristic gasket set with bolts on ebay for $75, have used that set on 4 motors now with no issues, just make sure 110% that the block has every bit of crap off it or the MLS gasket wont seal. Also yes, I have used "heads Only" on ebay on 5 motors with no issues too, there are a state away from me and ship same day so I get it the next day. Dont forget new rod bearings, oil pan gasket, timing belt kit and new piston rings, I dont recommend using the NPR rings, I use "sealed power" rings from advance auto parts. Pretty straight forward build, just take your time, clean out the intake manifold and egr passages and torque EVERYTHING to spec.

Thanks Donny. That's mostly what i was looking for. So you choose to use the bread that's shipped from Texas instead of the one from west Virginia?

The junkyard has about 7 sohc cars all lined up and they all have bad motors. I plan to just start pulling heads and take the first rebuildable block I find. Possibly grab an extra piston and rod from cyl 1,2,or 3 of another block to use in place of the #4 in the block i rebuild since it seems like #4 is the problem in then all.

The only block you can use is the sohc block the rest are completely different. I can go into detail if you would like.

I have a bad sohc engine sitting at a friends house if you would like I can open her up to see if the block is in good shape.

Thanks for the reply. No need for the details. It would be information I would likely never use again. I just didn't know if there was a reason to use one block over another since I had to buy one anyway. Seems as ford does things a lot differently than Honda does. Please don't punch me in the face for being Honda loyal for the last 18 years. Not for the riceer factor bit for the reliability and ease of maintenance factor.

No need to check on your block since shipping alone would Probably cost as much as ill be paying at the u-pull-it yard but Thanks anyway. It's greatly appreciated.

I wouldn't want to change crank because of the other related partaking involved also but this new head doesn't come with a cam. Is there a better cam I can source from a different car to get better fuel economy but not have to do any ecu tuning?

Thanks for all the help

as far as another stock cam goes... no. escortfocus.com used to offer different cams, but those are long gone if I'm not mistaken. It also has a cam position censor that bolts right next to the #4 cylinder.

there also are/used to be (?) Kent cams or something for the 1.9 I think that fit... but I don't remember.

Yeah, I'm not going out of my way to get an aftermarket cam since the plan here is cheap, simple, reliable and good fuel economy.

Looks like this is going to be basically a completely stock rebuild which is fine with me if thats my best options for what I'm looking to get out of the car.

Any other tips, tricks or suggestions you guys can make as far as making it most fuel efficient as possible before I go gather my parts this weekend?

Thanks everyone for all the help so far. I'm sure there will be more questions in the process.

Ill send this thread to a friend of mine. He is a sohc junkie and knows the ins and outs of these like no body else I know. He has a performance cam in his and he been working on a turbo set up.

He'll be the best person to get info from.

Thanks. I would love to hear from him. I'm trying to take in as much sohc info as possible for this build. Hopefully after that she will have a reliable car to attack and murder every curb that gets in her way and I can forget everything I learned about this engine.

All the curb comments arent even jokes. She wanted a good looking set of wheels on her Honda accord so we got a nice set of 17" enkei wheels and those little rubber bands that you cant tell if they have air or not. A year later they all look like you took an angle gringer around the whole wheel and one even has a bend in it. Actually chewed off half the thickness of the sidewall of said rubber bands. Talk about driving by brail. She just says "they put the curb too close" and acts like its no big deal. Sad part is, we live in a rural area... We don't have curbs, we have an asphalt driveway. My local alignment guy loves us. I hope the focus has a strong front suspension and steering system....

A good "tune up" helps. If you can get your injectors cleaned or replaced for factory flow, that helps. fuel filter. stay away from Bosch spark plugs and use autolite or motorcraft, gapped properly. Take a look at how the gasket matches up to the intake and the intake/exhaust ports on the head and see if a slight porting is necessary. Don't do too much, just clean it up otherwise you will lose some of that turbulence that helps aid in proper air/fuel mixing for optimum mileage.

If you're buying a used cam, observe for wear. If the lobes are worn down, it just won't run as well.

what is your goal? grab a bare block and new internals? and then an eBay head. I see cheap is the goal, and that's fine. check Rockauto.com for both your internals and gasket sets, as well as the maintenance items. Love them. You can always Google search for their 5% discount code.
