Not me 40 years on the tools and still love it.
Rather spend my day doing that than updating software on current rubbish.
Haha, I'll soon be embarking on DIY with the QP and actually looking forward to it. Mainly general service stuff but should be rewarding.

What a fascinating read, thanks for sharing.

My first ever track day just over a decade ago was in a 360 around Silverstone - and whilst I’ve driven things since which are much faster, driving that 360 remains as my fondest memory of a track experience to date.

If money was no object, I think top of my car shopping list would be a 360 CS!

Did Voicey say anything about why the keyway between the oil pump stages broke?
We dont honestly know... it’s got to be metal fatigue... after all, the engine has done 100,000 without a major fail.. just as well I suppose that we had to take it apart because of incompetence! ... we’d never have known about the oil pump cog failure otherwise.

I wonder whether it was installed a bit forcefully in the factory and been ready to let go for 100k. Super lucky it didn’t do anything nasty.

That’s how I look at it.. both Ed and Aldous @ AV reckon it was a lucky escape.

I just received further updates from AV Engineering.
Upon disassembly of the engine parts they encountered a problem when attempting to remove the worn bearings from the the front cover of the bottom half of the block, see photos below:
63088
63089

The bearings were corroded so hard into that cover that it actually cracked on removal despite AV trying to heat it up in order to remove it:

63090

Furthermore, one of the oil pipes also cracked on removal due to corrosion:
63091
63092
63093

These are serious issues as the cracked cover can only be purchased as part of buying a new sump which comes in at a ridiculous cost of thousands and the little cracked pipe replacement itself is £350 + VAT!

However, once again, the team at AV Engineering have stepped up to the plate and come up with a cost effective solution. They have managed to source both items from a scrapped 360 engine for the princely sum of £250!
Obviously I am extremely grateful to them for taking the time to source these things and more importantly at such a low cost. Hats off to these guys - not a lot of people would have gone to the trouble they are doing for me, very impressive indeed.

A second issue raised its ugly head when Ed at AV took the inlet manifold apart for a thorough inspection and clean up.
The 8 inlets each have a butterfly opening/plate which are held down by 2 screws..
As you can see from the attached photos one of the plates appear to have a screw missing!

63094
63095

They found the screw wedged in at the corner of the inlet manifold!

63096

Phew.. another lucky escape! Engines have been known to self destruct with screw like that dropping in..

A second screw was found to be loose also:

63097

That's it for today - my scored crank is starting to look like a blessing in disguise!!
Thank you to the AV team for all their hard work so far - without them I clearly would have been in a lot of trouble sooner or later..

This is a great thread, you get the impression that it could have been a lot more costly!

Meticulous work the level of detail that is needed to protect this type of performance engine
