I got my LR4 back last night. The timing chain noise is 100% gone. My mechanic told me it’s now as quiet as a 5.0 gets. Aside from the faint tap tap tap from the injectors and high pressure fuel pumps, it’s as quiet as my LR3 4.4 was. I also no longer hear the engine at all when at a stop. All I hear is the exhaust note, instead of the awful rattle of the timing chain.
The drivability is also much improved, which could be from the new injectors or a timing chain that isn’t stretched. I’m sure the timing was quite a bit out of wack before. The top end Power was always fine, but my low and mid-range power seemed to be suffering. Before I had to really give it some gas to get it to accelerate. Now it takes off from the instant I press the accelerator. It is also noticeably smoother!
It’s pretty windy and rainy this morning, so I’ll get an ‘After’ video when the weather clears up.
