Cylinder sleeve failure or something else?

No probably not mate. I will look after mine but they dont last forever...

Cheers

I believe it will be a high compression pre- Thor motor with 110,000km on the clock. Probably the same as ozscott’s. That’s about all I know at this time.
I hope this one will last for ever, or at least longer than the 178,000km I got out of the 4.0.

Look after the cooling system and it probably will! [smilebigeye]

A 4.0 and 4.6 Thor have the same inlet/induction system size. If it is a Gems from a RR then not sure.

As the new engine is a Gems 4.6, just pull all the Thor stuff off the 4.0 and put it on the new engine - the Motronics ECU will adjust.

I have always looked after my cooling system, didn’t stop the block from cracking.
Anyway, quite enjoying the process. [emoji41] Here’s where I’m up to:https://uploads.tapatalk-cdn.com/201...60e13021f6.jpg

Nice mate. You will like the 4.6...

Cheers

The 4.6 RR thors run bigger airbox outlet tubing and maf,,
(but the 4.6 will run quite happily on the standard 4.0 size.)
I changed all this to get the last 1% out of the conversion, the map inside the Tornado is different with these.
Noticeable? probably on the dyno..

gotta love the adjustable lifting gear[thumbsupbig][thumbsupbig][thumbsupbig]

Oh OK didn't know that - but the actual manifold and throttle body is the same though - I do not have a MAF (just a tube and air sensor) on my engine and the air cleaner housing is a lot larger than normal.

I didn’t know that either, but if it runs fine with the 4.0 setup, that will do for now.
4.6 V8 arriving on Wednesday. [emoji106]
