Are there any reputable aftermarket companies selling a high quality timing kit for the X350 4.2? I see a lot of cheap kits available on eBay but very little information about the brand. After I finish my suspension rebuild project I'm going to replace chains, tensioners and VVT equipment. I'm at 152k and I can hear a little bit of clatter under the timing cover when the engine first starts up cold. Things quiet down after it has warmed up and it seems to also be running lean on bank 2 as the fuel trims are 3 or 4% higher than bank 1. If I'm going to open the front of the motor to investigate I might as well just buy the parts and restore it.

 

Just had mine done. Talk to Tom @ Home - Tom Lenthall Ltd - Jaguar Land Rover Specialist
Phone: 0118 973 1614 I think he charged approx £300 for the kit plus £370/each VVT.

 

They are a great company to deal with.

I am sure you know but just incase make sure you get a quote excluding VAT.

Problem is shipping cost from UK to US.

 

PCMOS, Am I correct in assuming that by running lean you mean you have high-ish minus STFT's and plus LTFT's on bank 2 and they are higher than on bank 1?
What is the potential link between bank 2 Timing Chain Tensioners and running lean, please?
