Hey Y'all, so my 2010 Range Rover SC is starting to make the sound and is now accompanied by a check engine light. Before I start taking it out for estimates, I am curious what some of you have paid recently to get this fixed. Being SC, I assume this will include more man hours to fix? I saw on some other posts it is usually quoted at about 18 hours. Is this true for the supercharged version also? I have seen some folks post they paid between 3 to 5k more recently.

Thanks for any info. My hope is to not get taken advantage of when I bring it to the RR specialized shops.

I have a 2012 RRSC with the same noise, sounds like a Diesel driving down the road. Loudest at idle. Does anyone have a copy of the RR Bulletin regarding this issue?

catman - thanks for the bulletin.

9.2 hours, OUCH!
I'll check with my local RR mechanic to see what the financial damage will be to replace the tensioners and levers.
If I can put up with the noise, what's the ultimate damage to the engine . . . the timing chain drops?

what's the ultimate damage to the engine

behind the tensioners is a small port that feeds them with oil. RR lists the oil orfice as needing to be replaced with the tensioners and guides. This step was skipped or overlooked at my Independant RR shop. Pieces of teflon from the guide, and if gone long enough, metal will be floating around your engine if not picked up by your filter. The variable timing on the cams as well have oil going through them, lifters, as the well as the oil ports for the tensioners, and may become clogged or restricted. I paid 3500. in Richmond VA to a shop that was able to do the job without removing the supercharger thus saving hours of time. It was cheaper than the dealer, but the slight lifter tick makes me think twice about continuing to drive it with the noise, and wish I hadnt. I purchased it with the bad guides, and dont know how long the previous owner pushed it with the noise either.

Thanks, Dan.
My Independent RR Shop was started be the former Master Mechanic at BMC RR in San Francisco. He mentioned it to me at the last check-up that the tensioners might be the noise - so it's only been a short time. I'll forward this thread to keep him in the loop about replacing the oil orifice. I'll update everyone with the cost after I have the work completed.

I had the complete timing chain repair done (ALL parts), new water pump, new cooling tubes, a driver side door module replaced, etc...the cost was much less than quoted at other LR dealers (I called 4 total for estimates). The dealership that did the work was Land Rover of Fort Worth, TX. Fantastic work and better quote than the others. Would highly recommend. I chose to do the repairs on the TC and cooling system just as a precaution because my wife drives this as a daily driver and will do for some time. Vehicle has 91K miles and was not symptomatic. Justification was easy....vehicle is immaculate and have you priced any new 4x4 Luxury SUV'S lately with the capability of a Land Rover? Easy decision for me.

I had my favorite mechanic perform the work and he convinced me to first try replacing the SC bearing only. $1,200 later he informed me that that was the worst SC bearing he ever replaced. The noise was still there so I decided to have the complete timing chain repair and, like HCF_Customs above, I also had the water pump, spark plugs and anything else that needed to be replaced changed so I wouldn't have to deal with the repairs in the future. My mechanic credited me 5 hours of labor (for not performing the work the first time) and my second bill came in at ~$4,000 parts and $3,800 in labor. I didn't want to spend the money on a 2012 SC, but she's paid off and in perfect condition with only 72k miles. So far, she sounds and runs great.
