Agree...I am wary of anything they say. Eg..owner of a new F150 with the Lion engine was told the new forged crank is US made and not French which seems like a blame/excuse strategy to me.Quote:

Cast, if forged they wouldn't snap but that won't help with spinning bearings.
Chicken or egg?Quote:

And no, I don’t want an answer. This topic cracks me up. I’m so spun out by the endless debate. If I hear anything more about cranks I’m going to snap.
a lot of the trouble is wrong oil or it being not changed enough but they also can break thrust bearings lowering the oil pressure.i have reconditioned engine for 7000 au exchange
Thrust bearing wear is real. I recently had my bottom end rebuilt after thrust bearing end play.Quote:

Also replaced a couple of valves for the air pump, replaced the battery. So there is well over $4,000 in "extras" The final invoice came to $30,460. It has done over 10,000 k's and seems ok. Been off road and spent a couple of days in Low range and it's doing everything it's supposed to!! Chewed through the oil at first, well, hardly chewed, it used approx 700ml at first but that seems to have settled.
I am happy with my decision to get the rebuilt engine. When I first started looking for a second hand engine I was quoted $17,000 for a 115,000k engine and a further $5,000 for fitting. That with having to replace timing belts either straight up or in another 50-60,000ks, and it was a no brainer for me at least, but obviously not for everyone.
Eddie.
Just an update for anyone who is interested. The new (rebuilt) engine has another 10k on it and it's all very boring. Nothing to report except that oil consumption is now approx zero.
I still can't help but listen to every sound but can't hear anything out of the norm.
So far I am happy to recommend this engine. If anything untoward does happen I will surely post it here.
Cranky Bugger! Not bearing up under the pressure huh?Quote:

In Pt2 he comments on the location of the oil filter a long way away from the oil pump and upside down so as not to retain oil.
