I hear and see a lot about the TD6 snapping crankshafts, but how many people have actually had this happen to their D5? Seems like a lot of hype. I know it’s an issue but is it really the issue the interwebs make it out to be? I have a 2018 D5 TD6 with 63k miles, for context.

 

Me. happened. Luckily with 3 months of warranty and 5000 miles left.

 

If you want some entertainment on the subject, check out the LR Time youtube channel. Full explanation of the LR diesel crank issues.

 

Was there anything you were doing that could have led to the failure, ie driving habits, lots of rapid acceleration, towing, stop and go traffic etc. Also what MY?

 

2019. HSE luxury. I don’t tow. I bought it used with 24,000 miles on it. I drive 40,000 miles a year. 95% is going down the interstate at 80 miles an hour towing nothing. So I had it for about 20,000 miles. It’s just a known issue.

 

Awesome video, thanks for sharing! The LR specified oil for the TD6 is 5w-30 C1 which has an HTHS number of 2.9. As I understand it, a lower HTHS number benefits fuel economy. I run a 5w-30 C2 oil with an HTHS number of 3.5. I've read that 3.5 is a sweet spot for fuel economy and protection. I did stay with the LR recommended viscosity of 5w-30. After watching this video, I wonder if I should run a W40 viscosity oil in my engine.

 

My crankshaft is fine 75k km and counting possibly reason for failing not using right oil and intervals I'm sure a lot of people on this forum haven't had that problem but never bad to make sure it doesn't fail.

I wonder why the Ford diesel doesn’t seem to have this problem. If you read the above it talks to Ford’s lead engineer who states they redesigned the crankshaft for Ford and in the same sentence states these changes were adopted by LR for their engines as well.

 

I noticed that contradictory statement as well. Perhaps JLR did benefit from some of these Ford improvements and the crankshaft/bearing upgrades were not among them. To my knowledge, I know of two crankshaft/bearing failures on the TD6, one on this forum and one on the UK forum. I found this article of interest
The 4 Most Common Ford 3.0 Powerstroke Engine Problems (dieseliq.com)
It looks like powerstroke's were unique in the Ford F150 2018-2021 and we got the old Lion design.

 

According to my dealer the crankshaft was Land rovers design/component
