All of that makes sense to me except maybe the cylinder rings.
Jaguar went Nikasil in the AJ8 engine but had issues so reverted to steel liners around 2000ish. I seem to recall a few manufacturers having issues including BMW.

Nikasil is a spray-on process AFAIK. Not only Jag but others went that way too. They're fine so long as that engine's not been run on sulpher content petrol that was phased out in UK in 2000. Last region I'm told was the northeast. But prices for '00MY and earlier X308, either 3.2 and 4.0L despite being in otherwise 100a1 condition are much reduced. At least for those that've done their research. I was lucky, I didn't know of the Nikasil issue when I bought my first of three -- it was an '01MY

AFAIK there's only no8 as bad as that pictured. He's going to check out the lump first before committing.
Haven't heard since. The M62 was also used in the 735i and 835i (?) Dunno, not up on Beamers -- a lot of car unnecessarily complicated for a small cabin
The M62 appeared in the E38 7'er in 3.5 and 4.4 form, in the E31 8'er 840 in 4.4 and also the E39 5'er 540 in 4.4. The 4.4 and 4.6 was used in the E53 X5, and the 4.6 in the Alpina B10 and Morgan Aero 8

Popular or not, still don't think 5mm between adjacent cylinders in an alu block's a good idea. Mebe engine heads in here think it is?
When I get it back, I'll treat it like the highly strung tart she is.
Deutsche Ingenieurskunst? It's a myth
Jag's XK series went on for years designed pre-1950. And the AJV8 series goes on to 200k-ish with 10k oil changes. In the US Ford's V8 soldiered on
thru the war to the early 60s (OK lower compression, but you get the picture?)

I have had 2 German cars, the engines in both were crap.
I don't think Nicasil is suitable for anything other than high performance cars where reliability and longevity are less important.
The early AjV8 with Nicasil liners was NBG as my son in-law will testify.

Had a VW Passat SEL tFSI 2.0L that VW Racing re-chipped to increase from 190 to 236bhp on dyno
Added a few bits from the USA to make it go with some reliability but there were still basic design flaws that they described me that, if left unattended would reduce engine life. Didn't drive it around over the 10 years I had it (my father had a snub-nosed P3 that just went on, and on, and on) too wildly, just on occasion when burned off by one of the Golf GTI mk II "boyz". When I'd burn them off They don't line it up 'em Capt Manwaring The TSI 2.0L with chain instead of belt is reported as much better...
Course, this wasn't done on the public road. Oh no -- it was Biggin Hill airport perimiter...

Just had some dispatches by runner from the front line. M62 starting re-build. New crank, replacement second-hand heads skimmed and "re-honed" (whatever that means). Don't quite know how I'm going to get up to Peterboro to collect though given latest mumbles suggesting "lock down" restrictions not going to be relaxed until June
The 2.0tfsi is a disaster waiting to happen, are they now on the third generation chain tensioner?Had a VW Passat SEL tFSI 2.0L that VW Racing re-chipped to increase from 190 to 236bhp on dyno

A client of mine had his tensioner fail while the car was idling. A 4000€ head repair bill from a Bosch audi specialist... He was a year and 10.000mls out of the good will period. That was a £14k car.... Sod the audi, vw, skode and seat group.....

Yes, the whole VAG group (don't think Seat is in north America) showed itself eventually to stink. Even mid-to High-end Hyundai shows them up nowadays.
Btw tFSI = belt, TSI = chain. Faulty tensioners on both. When I had my belts done at 50k had to force the shop to change tensioner: "...but it's still OK! I know that which is why I want my specialist-made non VAG from the USA tensioner installed to keep it OK." "But you don't need it." "I do coz I'm paying the bill that's why..."
Nice car once I'd got back to what designers had tried to achieve before component cost cutting dweebs got their mitts on it.

Looking good , is that a new block as well or did they repair the old one ?
Head skimmed means they have machined the mating face where the head meets the gasket to make sure it’s flat , the honed part is possibly the valve guides unless the honing was the cylinder bores of the block.
New heads as well or probably just exchanged yours with a set already skimmed?

Cleaned up the old one, clearing all the galleys, new crank, I assume shells, gudgeons, rings presumably outsize ones fitted.
Couldn't get my heads done due to workshop closedown so he fitted pair already "honed" and skimmed ones from someone's stock. Cost a few hundred quid more, but if I ever get to emigrate will be thankfull that I did it instead of just a plain rebuild/clean out just to make it run well enough to sell on. They found that more than one cylinder had cross-threaded plugs -- no8 (again) had been re-tapped. So that was another incentive.
Your encouragement is encouraging

Good show then, I am guessing it is standard rings and pistons, I am not sure you can fit oversize rings with standard piston but I am sure they know what they are doing, you might find that some of the marks on the bore were actually pick up from the piston rather than damage to the bore. The pistons are coated in ferrous material to prevent aluminum rubbing against aluminium.
All looks smart though, they may have honed the bores to standard size and then used the felt pad / paste to clean them up to size and remove the deposits - i have seen inside the engines but have not rebuilt any of them and if you man is a BMW specialist they would have done many. The felt pads and paste are what remove a few microns of aluminium exposing the silicon to give the wear resistance.
The plugs get over tightened and and steel plugs in aluminum threads is always going to have the potential for problems.

Now back with me in sunny South Blackheath.
Found many faults stored from scan with my iCarsoft after return from Peterboro -- just cleared them all to see what comes back
They found rear brake pad material disintigrated -- changed for new pads -- but brakes now feel spongy. Mech says disks are original to (116k) so rear pads would need sometime to do the increased travel those disks having done 116k miles. (?)
Hmmm... Brake fluid about 1" below the top of the resovoir's filter. I assume there's been a bleed all round including ABS pump. But a previous shop had done a hydroscopics' test on the fluid finding it over 3%. But they didn't do fluid flush out / change the pads in October last year that I ordered... ABS fault returned.
Air suspension pump seems to run on a bit longer than I remember it -- but last time I drove any distance was early December last. Mech reckons the pump's heat sensor needs change out. I hope that's a discreet component? But dunno where it's located. Diagnostic shows that fault coming back. As well as heat sensor. Switching Ride Height Change inhibit off allows suspension to sink to kerbside height (lowest LED) eventually. Driving off from cold following day brings it to normal height LED. But over 65mph when it was going back to lowest LED just brings up AIR SUSPENSION fault on dash LCD display. I've cleared all faults, they've not returned. But I've only been out in it twice since return from Peterboro when I kept the Ride Height Change inhibit on. Will try an over 65mph test again next. (Air suspension system CAN error) and (Temporary system de-activation)
The Lambda sensor came up as a fault with Engine EML on dash. Not after coming back from mechanics but after a 24 mile run. (Lambda control adaption fault Bank 1) Cleared with iCarsoft and hasn't come back again
Oh, and my brand new bought 16 months ago Yuesa 100AHC apparently gave up whilst car in workshop. Only now gives 6.7V off load and won't charge without sounding a Shhhhhsh! noise. Back to Halfords for that yesterday.
Apart from that, everything's fine
As to the engine rebuild, mech couldn't find a shop open to take my heads in for skimming but one shop had a pair of M62 (I assume M62TUB44) ex-stock. So had them changed out. New crankshaft, rings, shells, etc. but the same block well scrubbed. Temperature's not moved off the ½FSD the 183 miles since collection.
The caked on oil detritus was like hardened plastic and doesn't just break off but needs careful chiseling. I assume mechanic found a soda blasters still open around there somewheres

I thought there was some Adaptation routines included in iCarsoft? Could've sworn I'd used them last year sometime?
Mebe I'm losing it
... You? Losing it? Bwa hahahaaaaha! And since when have you have had 50 likes from those old fogies you hang around with in that forum? <crack!> "Yewwow!" Serves you right. That Range Rover better be fixed now after throwing all that good money after bad at it... Otherwise I won't allow you out of doors... "Yes dear..." <cringe>
