Hehe, well I'm an idiot - but I'm not complaining.

I guess those weren't head bolts, they're plugs for the coolant passages. Inside the spark plug valley of the head. Where you'd expect a head bolt to be.

I'm sure there are a couple Ford powertrain engineers snickering right now...

But the head is off, and the crank turns freely now. The reason it was stuck was after removing the flywheel, I had to thread the flywheel bolts back into the crank to keep the oil from pouring out(another WTF), and "hand-tight" is enough to bind the crank solid.

I'm beginning to thing the Zetec was designed by the same people who built "The Temple of Doom".

Here's a question - while the head is off, what should I use to clean the carbon off the pistons?

Brake/carb cleaner with a good scrub brush.

Funny story, with a simple lesson: if you do this, make sure to run the engine for a while when you first fire it up. My brother did a head job on his old Corolla ('78 or so, RWD one) and while he was in there cleaned up the tops of the pistons with carb cleaner. When he finished reassembly, he fired the car up for a few minutes and it ran great. So he shut it off and cleaned up and went to bed. The next day he tried to start it and it wouldn't run. It would crank fine, but no fire. he checked compression and it was low in all four cylinders. He had to do a complete tear down. The carb cleaner had carried all the junk into the piston ring grooves then dried into a solid mass and caused the rings to stick and thus, no compression. Everything worked out but it added a dozen or more hours to his job.

Running it for longer probably would have made the carb cleaner and gunk cook off.

when i was haniging out with my dad today, he said pretty much the same thing.

guess that probably means it will be 10x as expensive, and .10 as reliable as a similar initial investment. with less resale value, and ,more parts sourcing difficulty.

is it sad that thats kind of enticing?

Brake cleaner rapidly evaporates, even at room temp.
Miniscule is what concentration?
10^^-3?
10^^-6?
10^^-9?

There is some trichloroethane floating around right now in every breath you take.

I wouldn't sweat it, but if you do, then just wait a day or so after cleaning to fire up the motor.

Wow, I've really been slacking on my updates! To make up for it, here's "How I Spent My Xmas Vacation".

To start with, I splurged a bit and bought something I absolutely did not need, but it just seemed wrong not to top off the engine with it.

Photobucket

Of course, now the stock plastic oil cap won't suffice, so I'll be buying something a bit more vintage looking.

I also picked up the gasket kit for the engine and a set of ARP head bolts. I still need to get the timing belt kit and oil pan gasket. I also have a POR-15 engine kit, as well as some chassis paint on the way.

For those just joining in, the stock oil pan on the Zetec is canted at an angle to cope with the stock slanted FWD mounting position. If I were just building a cruiser, that probably wouldn't pose any problems, but since this car will see some sustained G-loads at autocross, I didn't want to risk using the stock pan. There are aftermarket alternatives available for RWD Zetec installations - but they're upwards of $500-$600...for just a cast-aluminum oil pan! Of course, there are dry-sump kits available too, but they're closer to $2k, and I'm not sure I'd have the clearance for the external oil pump.

After doing a bit of research on the UK Ford forums, it seemed like an oil pan from a Ford CVH engine could be made to work with a bit of modification. I found a salvage yard on eBay selling brand new pans for a late-80's Escort/Lynx for $45-shipped, so I took a gamble.

The good news is the bolt holes all match, as do the arches at each end. The problem, as I'd also read online, is there's not quite enough clearance for the stock Zetec oil pump, which is mounted to the very front of the engine.

This is what it looked like when it first arrived.

After a bit of fiddling about, I determined there were 3-different locations of interference, so the easiest option seemed to be for me to cut the front of the pan off and move it forward about 1/4", then slope it back into the pan.

Photobucket

I have neither the skill nor the equipment to tig cast aluminum, so this was going to be a JB Weld job. In order to get the fitment correct and also prevent the JB Weld from leaking into anything important, I bought some Play-doh to sculpt between the oil pump and the pan, and to seal up the edges.

Photobucket

Once I had the cut out piece back in place, I used small dabs of JB Weld on the corners to hold it in place, then once it dried I removed the pan from the engine, and went to work with the JB Weld sealing everything up. This is the current status. I still need to build up the right side to try and match the existing support ribs, then make sure everything is sealed up on the inside. I might go over the outside again to smooth everything out as well. Then it will be time to fill it with water and see if it leaks!

Photobucket

While I was having fun with the JB Weld, I decided to tackle the water pump. The stock orientation points the outlet downward at a slight angle, which happens to interfere with the Europa frame. There have been several solutions, including custom water pumps, notching the frame, or cutting & re-welding the water pump outlet. I chose the latter, only utilizing JB Weld instead.

Here's a downward view of the stock waterpump housing.

Photobucket

And here's the result after a chop & glue job. I'll go around this with another coat as well to ensure it's strong enough and water-tight.

Photobucket

Next on the list:

I'm considering making a couple baffles for the oil pan, but I need to test-fit the oil pickup and determine how installation/removal of the pan will work, and thus where I'll be able to place the baffles.

I still need to smooth out the throttle-body to intake ports, as there is a bit of a lip. Then I can check the mating of the intake & exhaust to the new head, and see if I need to do any porting there.

Once the POR-15 kit arrives, I start prepping the block for paint. Then after that is complete, I'll pick up the few remaining gaskets and start assembly!

Did you consider using a CVH's oil pump and water pump? I believe there were some differences in the Zetec as well, when you compare the Contour/Mystique, Escort ZX2 and the Focus.

One of the water pumps spins backwards so you can simplify the accessory belt arrangement, too.

I did not find anything about using a different oil pump in the Zetec?

There is another water pump assembly which rotates backwards, though I don't know the original source, or if its available in the US. I'm not sure it will matter much, other than just simplifying the serpentine belt routing. But I'll need to order a new water pump anyway, so I'll look into it.

Here's a good reference. You just have to wade through the 'UK' vs 'USA' part availability... Which is the hard part it seems... http://www.jimhearne.co.uk/zvh.htm

I believe when the gentleman talks about the Mondeo, the parts should be interchangable with our Contour/Mystique cars.

Ah, he started with a silver-top 2.0L Zetec, those are apparently different than the black-top variety fitted to the Focus(and others) over here. I'm not 100% certain, but I don't believe the silver-top was available in the US at all.

The mondeo and the contour/mystique had the same silver top ZX1, IIRC.

But this is reaching my limited knowledge from when I was researching my Locost Seven several years ago, so I will shut up now.

I ordered this stuff straight off the POR-15 website on 12/15/12. I logged in and checked my order on Christmas, and it didn't show any updates so I sent them an email. I received a very prompt response on the 26th stating there was a glitch and that the order had not processed, but that it would be sent out that day - and there would be no shipping charge! New Year's Day came and went, but still no package, so I sent another follow-up email on Tuesday...my package had somehow ended up in New Jersey??!?!??!! To their credit, they had a replacement shipped out and on my doorstep by Thursday, so despite the bad situation, I'd say they responded to my inquiries very well.

Reading the instructions with the engine kit, it's apparent it is designed for use during a bare-block rebuild. Since I'm only down to the long-block assembly, I will be taking extra care to mask off the cylinders and preventing the chemicals from getting anywhere near the bearings!

Chlorinated is. Non-chlorinated is A-OK.

Me, I'd leave the carbon alone except for what wipes off with a rag. It's just going to accumulate again with the engine running, and will find its own equilibrium in short order.

I spent the past week prepping the block for paint, and yesterday applying the base and top coats. A couple notes:

1.) The Marine Clean product they sell is the shiznit - The instructions state "Dilute 3-parts hot water to 1-part Marine Clean, spray on engine block until grease melts away, or scrub with brush." They weren't kidding, as I squirted it on with a spray bottle, chunks of crud were washing down into my drip pan. Keep in mind, I've already scrubbed the block twice - once with Purple Power, and a 2nd time with Brakleen.

2.) Be careful with the Prep and Ready. It gives a zinc phosphate etch to bare steel, and it will soak under/through masking tape. Which wouldn't be a big deal if you were sending the block out to be resurfaced afterward, but since I'd only pulled this engine apart to the long-block assembly, it made a bit of a mess. Fortunately, I don't believe it caused any damage to the gasket surfaces that may cause problems after assembly.

3.) The next instructions state to give the block a "thin coat" of the regular POR-15. Having never used the product before, I was surprised to see it come out of the can with the consistency of 10W30, yet their instructions made no mention of thinning it down, or a suggested ratio. I put it on undiluted, and it looks good now. We'll see how it holds up.

4.) It states that you need to apply the top-coat when the POR-15 is "dry to the touch with a light finger drag", which seems a bit vague. But I did notice there was only about 15-minutes from "tacky" to what I considered "light finger drag". So again, we'll see how it holds up.

Below is a pic of the block after being cleaned, masked, and coated with Prep and Ready. And then two pics of the completed block.

Next comes reassembly!

enxt time mask with duct tape after the marine clean. marine clean will eat duct tape, but the phosphorous stuff doesnt go throuh the adhhesive.

and youll deffinately be able to tell what fully cured is like. in about a month.

no thinninng needed. just goes on like that. and usually its about the consistency of latex paint, but its usually cold when im working with it. some really pretty incredible stuff.....
