Jesus ****! That’s some serious carnage. I’m surprised that that is all that happened to that sleeve. I can’t imagine how much it would take to completely destroy a piston to that degree. Thanks for sharing that! Note to self, ensure tensioners are properly set once installed! Haha
Holy crap! And I thought my engine was bad….all it had was a spun #2 cylinder bearing!
thanks for th@kansanbrit ! Although, I’m not gonna lie, you’re really scaring me as I’m currently babying my LR4 with 176K miles on it, because I haven’t finished my SC engine build…and have a new 2012 LR4 that needs a head gasket first. (Cause that’s going to become the new DD while the 2010 gets the SC upgrade).
I literally pray everyday the engine holds together and doesn’t slip the chain and blow!!!
I think the lesson to be learned from all this is to check your oil and please listen to the engine!
All the timing stuff failures produce engine noises long before anything come apart. I can't count how many times people have posted video's with nasty engine noises and yet they keep driving? Or they overheat the engine and drive to the next exit or back home. You just can't do that or you will destroy the engine.

Small update with another addition - if there's one thing I've always been a little bit disappointed with, it was the lack of side bolster support on my XF Supercharged, so I scored these two front seats from a 2012 XFR:
Installed and wired in.
The wiring took quite a lot of work as the connectors are completely different on the seats between the 2010 and the 2012, and I swapped the driver's seat ECU so I didn't have to worry about coding it, but basically everything works (bar a code about an occupancy sensor so I may either have to swap it or there may be a way of reprogramming it).
any plans for a harness/ harness bar now that you’ve gotten these bad boys in? I too have a non R and I debated on either having an upholsterer just add the side bolsters and the extra meat on either side of the headrest that I believe would retain a harness well or just buy a pair and essentially do what you’ve done here. Anyone ever try an F Type R front seat swap?? Those things are pretty sweet looking. But similar to the XFR seats, they are pricey.
Dave do you have the spec build sheet from Mahle for the pistons? Or the sticker spec on the box? Do you know if these pistons are lighter than stock, and were balanced from Mahle? Planning a performance build but starting with this one.
Mahle actually has his order saved and have all the specs on record and can reproduce it if you ask them. I contacted them at one point and referenced someone having ordered a set before and the gentleman told me that he has it on record and can repeat. Also to note, the Coyote 5.0L has nearly identical pistons which are readily available at a reasonable price (half price for the custom ones I had asked a few companies about making). Unfortunately the “Nearly” Identical happens to be that they are actually just a bit taller @ Center of Rod Pin- Top of Piston measurements. However, if you know someone willing, that slight bit of material could be worked off or you can locate a gasket company willing to make a gasket that will raise your cylinder head enough to work. Just thought I’d throw that out to ya.
