Technical Replacing Engine?

[irc]

Yep. Sounds like it's toast. You didn't mention it happened twice. Could have been head gasket leak pressurising the coolant and blowing the hose off. Either way, as DaveMcT said, you need to make sure cooling system is fine before fitting replacement engine (radiator and coolant pipe at front of engine, plus any other pipes you have any doubts about. Easier to fit while there is a big space)
Depending on age of replacement engine, also check water pump/timing belt, thermostat, core plugs and sump while it is out.
Probably change the clutch while you are there unless there is a good reason not to.
Sounds a lot, but bits are cheap, labour isn't. Unless you are doing it yourself.

Excellent list. Also add new oil seals to crankshaft and gearbox input. They will probably be ok but a leak later will be costly and access is easy with the engine out.

Hose popped off twice??

You did fit a new clamp when it first happened???


Impossible for a proper clamp. Anything above 14 psi is vented through the cap.

If the cap fails the plastic joints, seals on water pump or hose will all fail long before it pops of

Hey,

Yeah it happened once before. I didn't think much of it as I thought we fixed it and he was driving around without a bother for 3 weeks until I got stuck in heavy traffic and it popped off again. Ah well sure, we learn from our mistakes!

We took the old engine apart over the weekend, mainly for my curiousity and the hopes that I might learn something, but yeah, my mum saids it's knackered. (It's great having a mechanical mummy, heh!)

Shes found a new engine at a breakers. The replacement engine is slightly newer with a round oil filler cap at the front of the engine instead of the square one at the back, other than that it looks much the same, anyone know of any issues we might encounter?

Thanks!

Round filler cap came when the engine was tuned for later emissions standards. Later still, went to 69hp with variable valve timing.
Probably the early round cap will work without problems, but a later variable valve timing one probably won't.
Take the cambelt cover off. Cam pulley should show if fixed or variable.

as long as it has the same connectors, it should work just fine, my first time I got one with a manual throttlebody (my panda was electric throttlebody) so it needed the old intake manifold and throttle to work..

If there are any significant difference get everything that goes with the engine. If you get the ECU you will also need the speedo unit and ignition lock & key.

If the old car was high miles get the gearbox and the engine.

 

[FelFilth]

The only problem so far that we can see is that the end of the cylinder head where the ignition coil goes is different so the old coil wont fit on to the new engine. old engine was 04 evo1, new engine is 06 evo2

if i get the ignition coil for the new engine, does this mean well have to change the ecu?

thanks for all yere helpz guys!

Go Girls!!!

Apart from physical compatibility I believe they are effectively the same. The FIRE engine uses a wasted spark system, two coils each drive two spark plug leads. The ECU should work with any of the wasted spark coil pairs.

Try a custom bracket for your old coil pack but if that cant be done you'll need the correct set.

Wasted spark fires one plug at the correct time to fire the fuel mixture, the other plug fires simultaneously while the exhaust valve is open so does nothing useful - it's spark is wasted. It's a less costly setup than having a separate coil for each spark plug.
