Hi

I am thinking of swapping my MPI engine myself at the weekend and I was wondering how difficult it was to do and is there anything in particular I should be aware of?

I already have an engine crane and all the major tools required. I have swapped a carb engine before but this will be my first MPI engine. I'm guessing that it is basically the same as a carb engine apart from the injection specific components.

The new engine is complete with everything ready to go, so it should be a straight in/out task - fingers crossed!

Any advice will be appreciated.

Thanks

Luke.

Three hour job - just leave the gearbox in the car - saves disconnecting many parts ! Of course - if you have the annoying servo cluttering up the engine bay - you may have to take it off first!

I wouldn't do that as the reason for the engine swap is a broken gearbox! I hadn't thought about the servo - thanks

You cannot be serious!! (in a John McEnrow tone)

Dont be daft

I said it to Nightrain and I'll say it to you. This is not Minifinity so don't treat it as such

the big one is make sure you dont get oil presure switch wire mixed with crank sensor wire, else it wont start.

1 tin of plus gas on the nuts and bolts now especially the ones that hold the servo to the car and should not be an issue

Noted, thanks.

Thanks I will add plus gas to my list. Thanks

Why would you attempt such a thing. Do you enjoy over complicating a job. less to disconnect! What maddness is this! You have a hoist take the lot out. I have no idea what particular drugs you are prescribed but I have never heard of such a rediculous procedure in all my days! take the engine out but leaving the gear box in the car! Maddness!

Trying to think which 'many parts' you are saved from disconnecting:
2x Driveshafts (which may involve splitting 2 top ball joints)
2x Engine Mounts
1x Gear selection parts (either nut, bolt and roll pin or 4 bolts (ignoring wand change))
Possibly gearbox steadies
Speedo cable

In return you have to scrat about removing the 'box bolts, clutch cover, flywheel and idler casing in situ.

Hmm, I know which way I would rather do it....

You do realise this is a mini, a front wheel drive car with the engine bolted ontop of the gear box and not a Mk1 ford escort or some other rear wheel drive car. I just have to ask!

Can I just point out that leaving the gearbox in was a suggestion that was NOT made by me. It would perhaps be a little clearer if you quoted the post that you are referring to as it would seem from your reply that you are suggesting that I am mad for taking the engine out whilst leaving the gearbox in, which I am not doing. If you read my original opening post I have stated that I am swapping the engine and I am looking for guidance.

I have no intention of doing this and as per my reply, the gearbox is broken hence the need to replace engine with a new lower mileage item that I have purchased.

I appreciate people replying to my topic after all that is why I started it in the first place but can I ask we keep it relevant to what the original post is about. I am intending to swap my MPI engine including the gearbox. I have no intention of splitting the gearbox from the engine and leaving it in the car, my gearbox is broken.

I'm concerned that this topic is going to turn into an argument about pro's/con's of leaving the gearbox in the car and although that might be a good debate, it's not relevant.

Don't give out incorrect advice - if you don't know the answer, don't post!

Right now thats out of the way. I doubt there is a lot more work involved then a carb engine, perhaps a few more electrical connectors. Just take note of them as you are taking them off, a few pictures from a digital camera perhaps.

Its nothing you dont have the capabilities to cope with with, like as said you have swapped a carb engine in the past.

Thanks somone back on topic!

I have a load of zip-tie label tags that I intend to use when marking everything up but I hadn't thought of using a digital camera, good tip cheers.

It should be no more 'difficult' than a carb engine, maybe just take a little longer and the inlet/exhaust manifolds might be more fiddly. As said, more electrical connectors to remove & label.

I presume you will have to strip out the front mounted rad first too, wheras with the carb engine it could be taken out with the engine.

The mentioned flywheel sensors are prone to damage but if you are not touching the clutch cover as part of the swap I don't think you'll have an issue.

It might be a good time to replace the temp sender under the inlet manifold as these seem to be prone to failure and are a sod to get to when the engine is in - Sprocket would be better placed to agree whether this is worthwhile as I have never run and MPi nor know how expensive the senders are.
