Perhaps not cleared all material from first failure out of the crank's oil drillings / a gallery somewhere ..?

Impressive project!

The rear crank seal was leaking, seems crazy he had it all apart and didn't change it, or if he did, he got it wrong.

There's a special tool for the crankshaft seal which is quite expensive but I've seen what happens if you don't have it so I bought one. I also bought the correct timing tools for the engine.

I pulled the sump off, there was bearing material in it. Cylinder number 4 is the one that's knocking.

IMG_20221222_115650896_HDR

It's worn away the conrod cap, looks like he drove it for a while knocking, the bearing shells are totally gone.

This is where I'm at now. I need to strip the engine further to check for any other damage, assuming there is not, there's are 2 options I'm thinking of, take it to a local engine builder and see if it can be re-ground or buy an aftermarket crankshaft, they are £450 (£630 with the bearings). A re-grind would be a few weeks as they are shut for Christmas which would slow my progress down.

Fixing the problem is one thing but knowing the cause and working out if it's related to the first failure is another. If anyone wants to chime in with theory's, please do. It's a different failure than last time. It could have been assembly error, he re-used the conrod bolts, one could have been out of spec and caused the failure. He could have been supplied the wrong size bearings and the tolerances were wrong.

I know you said you had an invoice from Jag for the turbo, did you get one for the fitting the liners?

Because that liquid joint for the sump looks a little bit to factory applied to me, suggesting the engine has not been apart. Which would also explain the leaking main seal not being dealt with.

Don't these have issues with the oil feed pipes to the pistons, (cooling)

[Thats What She Said]

May be possible the previous owner, when reassembling the engine, got the conrods and end caps/bearings mixed up. So didnt match up the end cap to the correct con rod.

[Escy]

Some good suggestions there which I'll be checking over. Thanks.

Yeah, I have an invoice for the bottom end. It's definately been apart, there is a plastic clip on the windage tray to hold a wire that was broken. I don't know what he's used on the mating services, it's been difficult to separate things. More like an adhesive than a silicone, it reminds me of Tiger Seal.

In for the bumpy ride. Good luck!

I've a 2.2 diesel 6 speed auto Evoque that I'm looking to upgrade in the coming months, so it'll be good to see what you've got to deal with.

Keeping an eye on his.
Different for me to see a dirty ingenium rather than a nice new shining one.

[Escy]

Taking apart the rest of the bottom end. It's a mess. You can see the metal in the oil. There was pieces of bearing in the sump but the oil in general doesn't seem to be contaminated with metal in it, no sign of any behind the rear timing cover where the chains are. I haven't looked at the cams yet.

Crank out, I think maybe I should get myself an engine stand.

IMG_20221222_213314221

That's all the caps off. Every shell is damaged, it spun the big end shells on cylinder 1 and 3 as well.

Looking at it, I thought it had been knocking for a while but speaking to the previous owner, he said he heard a knocking, within 20 seconds the oil light came on and the engine seized.

It's worse than I thought it would be. I need to strip the top end down and see how it is. The crank journal looks bad but it's bearing material fused to it's surface rather than chucks taken out of it.

[Magooagain]

What's the score with the oil pumps on these?
Any known faults?

[shalmaneser]

That block is crap is it not? New crank + line boring + new Conrods at least?

Fair enough. Normally when people put liquid joint on things there is way too much of it.

I'm not a million miles away from you (I don't think) Escy down in Cardiff and I've got one you can borrow for a while if you want?

I need to inspect it a bit more, I'm going to take the cams out, if the caps are in a similar state then I'll need to see about another engine.

I was expecting a replacement crank/repair and at least one rod anyway so this isn't too far from what I thought. I'll now need to replace all the rods but they aren't expensive and probably the oil pump which is expensive. I'll strip that down first.

None of the mains span a bearing and looking at the damage, the closer they are to the knocking rod the worse the wear. I wasn't going to get line boring done. Would that be a mistake?

[Shedding]

Is one of the big-end bolts sheared?

That's a great offer, I'll send you an email.

[Megaflow]

Shedding said:

I think it is more than that, I think part of the cap is missing as well, the bearing keeper groove is missing as well.

[Escy]

Yeah it is but the bolt snapped on removal, the cap is worn away, there was loads of movement in it. That's why I thought it didn't look like it knocked for 20 seconds before cutting out.

[Pepperpots]

Do you think it is worth repairing or even repairable to begin with? Looks like mostly internal stuff as the block (from my inexperienced eyes) looks ok

[Shedding]

Do you know which cylinder needed a new liner and is it the same one as the most damaged big-end? Also, possibly nothing, but why does the invoice for the engine work say "draft invoice"?

Maybe the engine work up to that point was a WIP and more work was expected?
