448DT Engine rebuild

This site contains affiliate links for which LandyZone may be compensated if you make a purchase.
They're not in the workshop manual because LR didn't class it as a workshop repair, try your parts supplier or the parts manufacturer.
 
The 448DT is a bit 'new' for most on here...
Here's what is publicly available - I'll have a deeper look into the Ford documentation to see if there's anything relevant in there.

many thanks
 
The 368DT - essentially the same engine with a different stroke & piston diameter has crank bearing cap torque of 70Nm, con-rod bearing torque of 40Nm.
I can't find any accessible details of the 448DT - possibly locked away due to the spat between JLR & Ford...
