360 story and engine rebuild
Discussion

Thanks for sharing the story, great read. If I remember correctly, you also shared your 996 rebuild (hartech) a few years ago here? How was it so far, would you say it behaved well after the rebuild? or similar 996 issues came back?
Blimey, you have an excellent memory! Yes I had Hartech rebuild the M96 engine after a valve dropped in. It was lovely after that. Sold it due to lack of space during a house renovation and then made room for a Granturismo S. Engine is being run in at the moment plus a number of other little fixes being completed. Obviously not much is happening currently due to the lockdown but signs are good that the engine is in fine health following the rebuild.
I will update further when I have something tangible to post.
Thanks for the interest.

Nice news, this has been very interesting all round, Take care MikeI will update further when I have something tangible to post.

I have refrained from posting in this thread as I don't want to break any rules. However I think it's worth explaining how we intended to repair the crank if the scoring was too deep. What we would have done would be to machine it down to below the level of the scoring and then hard chrome plate it back up. The plating would then be machined down to the correct diameter. As it's just a sealing surface, the hard chrome plate would have been an ideal surface finish. As it happens it wasn't necessary - one of a few bullets dodged...
Another alternative would have been to reduce the OD to suit an undersize seal and what I would have done if needed.My experience of doing this regularly on industrial and high speed turbo machines fwiw.
I have had issues after hard chrome resizing rapidly wearing the seal lip which I think is down to surface finish and hardness as much as anything, it doesnt lap in. Also needs to very thin or it can spall. Either way not had much luck.
So tend to spiral weld and machine back these days as a longer lasting repair.
Just a quick update on this thread. Covid-19 obviously put somewhat of a halt to proceedings on finishing the car. However, AV have kept at it and the car is now finished and ready. I visited AV recently for a test drive.
Far more work and attention has been undertaken in addition to the engine rebuild and gearbox stripdown. Everything on the car has been inspected and assessed. I wanted the car to as good as new and if I’m honest, it’s actually most certainly better! The clutch has never been this easy to operate (soft as butter), the handling is unbelievably sharp yet smooth and steady, but the biggest difference by far, is the engine. Some of you may have already read Aldous’s blog about ECU mapping:
https://aldousvoice.com/2020/06/01/ferrari-360-eng...
The retiming of the engine that AV undertook, combined with the correct ECU map, tailored precisely to my car, has completely transformed the power unit, and I don’t say this lightly! (I’ve gotten to know the 360 engine quite well over 105,000 miles and in addition have driven many other 360s).
It simply is not the same car to drive, the instant access to power is incredible.. no lag, no waiting at low rpms, touch the throttle just lightly and it’s off like a scalded cat. I used to describe my 360 as ballerina, light on its feet and incredibly nimble... it still is, but with the added bonus of a Saturn V rocket behind the seats. It has absolutely transformed the car and I cannot wait to collect it and put some serious mileage on it once again. Bravo AV Engineering!

Sounds like it might be time for that photoshoot mate
Drop me an email 
Well done Bebs. Anyone lucky enough to see this 360 in the flesh will be shocked. Even before the work, it just didn’t look like a 100k mike car. Can’t wait to see it again soon.
Amazing really, and great that it will continue to be a driver and not a garage queen.
Also one of the most F1 sounding 360s I’ve heard!

What a fantastic thread to read! I'm about to embark on on an at-home engine rebuild for my 20-year-old 210k mile BMW 330Ci which I've owned from new. I may also be looking to swap to the 6-speed manual gearbox from the 5-speed manual I already have. This has given me a taste of what sorts of horrors I might find when I get in there. Apart from helping with re-building engines for racing hovercraft when I was at school, and doing my own brakes/rotors, replacing external engine accessories and things like that. I don't have any serious spannering experience so I'm hunting down rebuild stories like this so as to gain experience of what kinds of things go wrong and what potential solutions are. This thread has been a small goldmine of information - how I'd love to spend a few weeks at AV Engineering soaking up knowledge! Currently trying to work out exactly where I'm short tool-wise and where to source the best replacement parts, OEM or otherwise, so as to bring the engine as close to possible to new condition!
Thanks again!
Thanks again!

When you're rebuilding your 330i make sure you uprate the oil pump.Thanks again!

The oil pump? Nobody's mentioned this before. Is there something wrong with the oil pump? I've heard of the issue of the pump sprocket nut backing off, so people install a castellated nut and wire it in place. Is that what you mean? I have a thread at https://www.pistonheads.com/gassing/topic.asp?h=0&... if you want to answer there to avoid polluting this one too much - thanks!Edited by LunarOne on Sunday 26th July 13:08
There are loads of photos on the earlier part of this thread. Apart from the mechanical engine rebuild and engine bay restoration, much of the further updates and work was replacing worn suspension, AC compressor, wheel hub, clutch/flywheel/release bearing, gearbox cassette inspection and so on, on a like for like basis so not much to see there.
Recently I’ve been putting some mileage on the car and I’m still blown away by the power train transformation and handling. It seriously is hard to believe that this is the same car that went into AV Engineering for a timing belt service!

Fascinating thread.
Dare I ask what the work cost?
It won’t make any sense to put a total figure on here as so many additional things not listed on this thread have been done to the car to bring it up to ‘as new condition’ Dare I ask what the work cost?
With regards to the actual engine rebuild the fixed labour cost was 45 hours at AV Engineering’s standard hourly rate to remove, strip down, assess, rebuild and refit engine. Obviously this is plus parts, which all depends on what exactly needs replacing. 8-10K in parts just for the engine is probably not far off the mark for mine.
