Morning Ashley

Welcome to the Forum

OUCH !! what happened ?

If you talk to a BMW main Dealer they will be talking about New Engine (they dont repair anything just replace stuff. You will get the same from some BMW specialists.

A rebuild using genuine parts can be costly depending on what is replaced, when I rebuilt my 4.6is engine parts alone came to £3k (OK it is Alpina based and all parts were through BMW) if I had paid a garage I guess the bill would have been about £6k with labour

So how much are you able/capable of doing yourself 

As for sourcing an engine there are a few BMW specialist dismantlers/recyclers near Manchester (google will help) there is also a register of BMW Specialists talk to a few of them to test what hourly rates would be involved if you need their help. I would guess that a replacement would be between £1500 and £3 or 4000 depending on what's included. Don't just buy an engine and put it in budget for sensible things to be replaced such as. Timing chain guides and tensioners oil pump and drive water pump (electric on your car and a BEECH of a job with the engine in the car) Also which engine single or twin turbo as you may also need the DME

Good Luck

Its a single turbo and i dont have the time to do the work my self i could if had time bit work prevents that engines reconditioned with good parts fitted are coming in at about £6700 fitted

If your paying for the work I would say that is a fair price but get references and always remeber the old saying 

"If you think Professional is expensive wait until  you have to pay for Amateur"

Good luck with the work and remember to run it in with care

Have you tried quarry motors at Sheffield? I’m sure they do a fitting service too?
