I've heard alot of talk about the I6 aux shaft breaking and was wondering hwo common it is for then to break? My EL has 163,000 on the clock and I drive it sensibly so would the aux shaft still break at some stage or would the car need to be driven real hard for increased chances of it breaking?

my car had 171000 on it when the aux shaft went,as far as i can tell it was well looked after driving wise, it all comes down to the condition of the dizzy gear or what dizzy you are using, if your using a chinese dizzy it wont match the e series aux shaft properly and chew it out, or if theres play in the dizzy shaft it will chew it out

Your answer is how long is a piece of string.

I've had one fail at 280,000km, and I also had a fairlane with 500,000+km on it that never even had a head lifted.

Maintenance, Luck and Magic are the 3 variables. guess what you can control.

I've still got the original dizzy in mine so fingers crossed it doesn't give me any trouble for the next few years.

Are they likely to have issues with an original CAS in an EF? I've heard that vertical play on the CAS shaft can cause issues? Not sure if its aux gear issues though. Any tips on how to look after it, or anything that can be done during a engine rebuild, since they can't be bought new anymore?

Some of the problem is when the cyl head gasket has been done, the timing chain tensioner hasn't been installed properly.....usually too tight.....this can even flog the block out where the aux shaft runs.....seen this with my own eyes.
And have heard of poor quality cheapy dizzy's gears floggin the gear on the aux shaft too.
Lack of oil changes won't help either.

i think this is what phongus found with his spare engine he had removed from his fairmont, the hole where the aux shaft goes in had been elongated by a timing chain being too tight
