How about removing the head off the old lump, now it's out the car, and having a gander? I'm also trying to think where the bloody heck the gearbox could be leaking from!!

I am beginning to think that the donor engine has issues. Possibly a failed or faulty injection pump, or maybe something wrong with chain, its tensioner (if it has one) and guides - Sassanach and I both heard a rhythmic 'rubbing' noise intermittently, but where unable to pinpoint it, as we were busy trying to unblock the road Embarrassed

Original reason for doing whole engine, is it looked easier, trouble sourcing new head (plenty of bottom ends, heads rarer - what does that say Huh

), lack of tools (needs a special locking kit that locks the crank and chain guides), and cost (by time I'd bought all the gaskets and bolts needed for head removal etc)

Plan B is to remove head on original engine. There is evidence of the stuff put in cooling system by previous owner (the copper filing 'hg repair' stuff) on the injectors.

Now, over to the experts - the injectors sit in swirl/precombustion chambers, so if it was just a failed HG, could the copper filings have reached the injectors? Or does this definately prove head is fubar? Additionally, if that is the case, can the head be repaired? Or should I use the head from donor engine?

Problem with Plan B is if the engine is OK, and its an electronic problem (no codes on Tech2 - odd spurious one if it stalls itself), then that will be more expense for nothing Cry

Blimey! Take up the manufacuting tolerances in software Roll Eyes

and don't make it self-learning! OK until someone changes one or t'other then it's foobar!

I reckon we're getting warmer, though. Either the pumps need to be swapped or the pump on the new engine has suffered from being left standing...

The othere specials are a couple of locking pins.

I love buying broken things Seriously though, have you tried giving it an Itallian tune up? with a splash of pump oil? the VP44 doesn't self lubricate like other pumps. Also you could try swapping the pump electrics too and see if this helps.

Read that on the BMW TIS, seems that only affected early ECUs (ie, a new pump needed the ECU to be upgraded) is my understanding....

Omegatoy has just popped round with further info - something that I did consider last night, hence swapping heads and engines....

Picture to follow...

Aug 2007 at 12:27 So, whats easier/cheaper - changing chains/spockets/guides or changing heads over and swapping engines back? Or worth changing pump first? Bit loathed to do that, as I have a working block with pump all timed, just needs head fixed?

I think you might be better just having a look at the chain etc first before you swap anything else.
Did you hear it running before?

Maybe you would be better off pulling it out and fully rebuilding it?

Sorry, I know it's hard to take on board the worst case scenario but in reality in may be quicker to do and you should see 100k before you get an oil leak. Thumbs Up!
