This is sad that LR keeps on producing defective replacement parts knowing there are issues considereing they are special and expensive vehicles that have loyal LR owners and followers of several years, decades also. Sure bet several decades ago LR's being basic simple also trouble free, let's not forget underpowerd driving a 58 LR but a hoot.
You would think LR would be selling improved replacement parts thus gaining owners confidence knowing they care, owners along with future new LR buyers also knowing LR going the extra step to produce a "reliable vehicle".
In the long run having more repeat buyers with the word out they correct issues also gaining new LR buyer purchase. This a win win for LR not happening overnight requiring time before the past and future LR owners and the general public gain their confidence back with LR.
Same BS going back with the 3.9, then the better improved 4.0 & 4.6 blocks LR did not complete the job still having issues of slipped cylinder liners. Going one step in the right direction milling the block deck and installing "T" Top liners forever fixing slipped liners the way engines should of been built making a reliable trouble free engines.
Owners installing replacement engines with the same flaw can possibly repeat the failures unless they had the brains to send the block out and machined to accept aftermarket "T" Top cylinder liners. Trust me on this imprpovement at 217 miles from factory new 4.6 shortblock install I removed then had the block machined then installed "T" Top liners (added a 4.9 stroker crank kit) making a reliable engine vs playing guessing games if and when a slipped liner may happen.
Another example the 5.0 timing chains and guides failure issues, that alone prevented a high percentage of new LR owners of plunking down their money as new LR owners.
LR owners blamed the FoMoCo machine shop division for 5.0 timing chains and guides failures when FoMoCo followed to the letter the blueprints (CAD drawings) every detail and spec every measurement along with type of materials LR engineers ordered.
FoMoCo machine division not allowed to alter their contract with LR altering specs and materials listed in their contracts.
You have an issue with failing parts or quality control, bring your complaints up with LR, FoMoCo machined engines only to LR specs along with other vehicle manufactures in Europe.
As I replied a couple years ago about failing plastic crossovers with my suggestion reply that "if I owned one" ( I like my improved trouble free 4.9 pushrod engine). I would of fabricated a jig along with having a donor 5.0 engine to work off, Tig welded crossovers front and rear out of aluminum ending those on going plastic failure issues.
How great is that to rely on plastic way out in the bush beyond any tow service, call the U.S. Army and have the LR Helicopter lifted out?
When you have a Bridgeport mill, lathe, metal cutting bandsaws, Miller 350 Synchrowave Tig welder (not the modern dummied down of fewer controls Tig welders. If you can think of an idea, design it things will happen.
Timing chains and guides failures on 5.0 engines, i'll keep my opinions and comments to myself being this being a family forum......~~=o&o>........
