Stupid me.
i think i've stripped the flywheel bolt threads in the zetec crank.
Either the bolts I bought were a slightly different thread or slightly too long.
What thread are they meant to be, I will run a tap down them to see if they really are buggered.
What options do I have if I have fubared them? Is it new crank time?

HeliCoil? not 100% sure that's expectable on the flywheel, but I don't see why not.

Bloke near me is selling complete engines with gearbox for £150. Cheaper than trying to fix a crank!

I wouldn't risk it change the crank you really wouldn't want a flywheel to detach its self .

If it's a silvertop then yes.
Crank is spot on, but breaking engine as one cylinder burns oil.
Got a head with new valve seals too. Oil pump done less than 250 miles. Cams are sold.
I used to be indecisive, but now I'm not so sure

It's a blacktop. Are the cranks different?

How can you strip all the threads? Surely if you stripped 1 then you would not strip another. What do you mean t he bolts were too long? Just
doesn't sound right? I would try a tap down them first, if works then no issue. the next option is to drill and tap larger, I defo
wouldn't use helicoils as too dangerous.

Not sure. The rods and pistons are different, but might use the same crank?

Quick Google says cranks are the same.

The comment above about helicoil
Do not helicoil a flywheel
Not even one thread
Not now, not ever.

What about a crankshaft? What's the problem with thread inserts, correctly done they are as strong or stronger than the original thread?

Stupidity, stupidity and yet more stupidity. Bought the flywheel bolts on ebay and they went in but were very stiff. When I removed them it looked
like the threads on the bolts had been changed and there was swarf on all the threads.

Been there with crank/flywheel bolt issues - got a lightened billet flywheel for my Zetec and had to change to allen bolts rather than the standard
bolts. When I followed the Haynes manual torque settings, 3 of the bolts actually stretched/elongated - luckily I didn't damage any threads,
but had to buy new bolts and some super locktite for peace of mind.
Artificial intelligence is no match for natural stupidity!

I've bitten the bullet and bought a new crate engine from kitspares.
I don't think they have a huge number of them left and think it would add more than the value of the engine to the finished car.
By the time I had got another flywheel, had it balanced, bought new cap bolts , I would have been spending a fair chunk of money anyway.

Remember and fit a new cam belt to your 'new' engine
Ford give these a 10 year limit regardless of mileage and they have been known to fail even on zero mileage engines...
You might get away without replacing it, but after all this effort and cash is it worth the risk?

Correct
All these engines were manufactured in 2004 thus are 12 years old.

Good call. I had just put a new cambelt and pulleys on the engine I junked so I can reuse that new one. I have to take it apart to a degree to put
the chopped sump on it anyway.
Hopefully, I can make a few quid back by selling most of the ancillaries on ebay. Exhauast manifold, throttle body, injection stuff etc etc.

Are you mad. You should never reuse cambelts even if they are nearly new.
The new engine cost you almost £1000 after skimping on parts on the previous one and now you are prepared to do the same again.
Get down to your factors and get a Gates kit that suits your engine code. Once done you are sorted for 10 years.
There's locost and there's stupidity.

Bit harsh when the engine's never even run. I'm sure his new cambelt will be fine.

Buy a second hand car you get a used belt etc, his belt has only sat for a year so should be good for 10 years....

Exactly. Brand new cambelt in my newly (as others have said took me a year to get to here) refurbished then fubared engine. I would have thought that
it's fine to just switch over.
