hi, i have a used engine which is complete with very good bottom end. i bought it with a view to refurbish for my td5 after the oil pump bolt let go at 140000 miles.i did not need to use in the end as i managed to stop in time with no real damage done. it has been in my shed gathering dust since i sold my disco 18 months ago if you are interested call me on 07704820159

So I finally got around to taking the head off/inspect the cylinder/ bearings on the old engine! It's not pretty... Most of the shells on the first 3 conrod/bigends have been destroyed, but cylinders/pistons seem ok (although I'm going on purely looking at them). I'm still going with the oil pump fail (bolt was very loose), friction, metal, more metal, more friction etc etc, and the horrible grating noise when turning engine over was literally the noise of the camshaft grating as it tried to turn. Pics to follow...

I personally would save yourself a load of grief and stick another engine in there. They sell for peanut's. That crank will need grinding or replacing and you will have a load of ****e floating round your engine ready to destroy the next crank and set of bearings.

This^^^^

It's pretty obvious to me that there's an oil supply problem. So you'll need to sort the oil pressure issues, as well as having the crank ground, new bearings and put it all be together.

Just get a replacement engine and move on.

You will at the very least need to strip the engine right down including removing all caps on oil galleries to flush and blow them through to ensure no bits of metal are there to cause more damage. Not many people are prepared to do this.
Get yourself another engine and treat this one as a learning aid. Strip it totally down as above then bluprint it. Then when the one you buy cocks up you will have a fabbo one to replace it with!

Already replaced and up and running! I only just got around to dismantling the old engine and wanted to share what I found...
