Thought i had joined the broken crank club but NO!

Thanks for the info Dazza.

I think what you say is correct, it is rare...

I'm still getting vehicles in with a broken oil pump housing, I have one now, i find it almost unbelievable there are engines out there that havent had this done.

LR still wont accept that its an issue so no recall was done, its only indies like yourself that are aware due to seeing the failures come in on a tilt tray.

Like mine did in 2015 https://www.aulro.com/afvb/images/icons/icon8.png either the pump flange failed or the bolt sheared, the nth side brisbane indie would not advise. Getting info from them at the time was like pulling teeth.

Think that terry engine is getting towards end of its life as oil pressure is low and will probably need to make decisions soon about another engine or another vehicle. Another engine is the preference if I can find one.

New latest version oil pump should help with that.

the broken tensioner bolt should not become an issue, replacing the bolt when doing a timing belt is very much the norm on any car for anyone that repairs cars for a living

I've got the 15mm impeller one to be fitted when it goes in for timing belts etc.

So in addition to using only genuine bolts, torqued to the correct spec accurately with a digital torque wrench, do you also put loctite on the bolt?

Other than wrong spec bolt, or wrong spec torque, the only other 2 explanations I can think of are either the bolt comes loose, or the mating surface between the tensioner and mounting point are not clean and straight (allowing for some flexing).

26Nm on a grade 10.9 M8 bolt is something like 50-60% proof load, so well below the yield point.

I always wondered about that, because Loctite makes a great lubricant for the threads.

This is exactly how i was at the time.. it was all about upgrading the oil pump.. i remember looking at the original pump and belt and saying it would proberly run for another 7 years

I do remember looking at the new bolt and the low torque setting and thinking how the hell does it keep running for all those kms but not thinking of checking i just fitted the kit supplied..

1 thing i can say for sure is it wasnt from AF as im 100% sure i didnt start using them till i started replacing suspension componets and wheel bearings..

As i said earlier im not going to name whom i think it was as its unfair to them and at the end of the day I did the replacement so its on me that i never was vigu thourough enough to do my research on the bolt.. lesson learnt the hard way..

Will update more as i know it but due to work commitments its going to be a slow process

Cheers Bulletman
