Range Rover Engine Rattling Noise

12/1/2017

We had this Range Rover come in making engine rattling noises.
We diagnosed two problems with the vehicle. The first problem was the timing chain was having issues and rattling. This is a common problem for many of these Rovers. The timing chain guides will break or the tensioners will go bad allowing too much slack in the chain. This will cause noise and potentially cause the internal destruction of the engine if not repaired.

The second problem was the supercharger. The bushing inside the nose cone goes bad allowing too much free play and no vibration absorption. Other than the noise this will eventually break and stop working altogether. There is also a potential for further costly damage here.

After approval, we repaired these problems and got this Rover working well again. It sounded good and ran even better. When we informed the customer of the vehicle being ready, he told us about another problem.

The third problem was the engine would sometimes make a whine or whistling noise after it has been ran for a while. The cause of this problem was in the PCV system which is built into the valve covers. The passenger side valve cover has 2 diaphragms that operate in the PCV system. Both of these diaphragms were leaking air which caused the excessive vacuum inside the engine to make a whistling/whine noise. This is where we all learned a valuable lesson. The valve cover can only be replaced after the supercharger is removed. We already had the supercharger (and both valve covers) removed to do the timing chain work. There would have been a lot of time and labor saved had we known about this problem earlier.

INformation aBout Your Timing Belt

AGCO Auto has as great article, When Should I Replace My Timing Belt?
​

At MY Automotive we have a lot of questions and concerns about timing belts, sounds, smells, and what a customer needs to do to fix their issues.
​

​The timing belt is a point of confusion for lots of people. The first point of confusion is that not every engine has a timing belt. Engines that do have timing belts require replacement at certain mileage or time intervals. Like any piece of rubber, a timing belt deteriorates over time. To figure out if your engine has a timing belt, refer to your owner’s manual or ask to a trusted professional.

A Timing Belt and a Serpentine Belt are Not the Same Thing.
Some vehicles also have exterior belts and serpentine belts. Sometimes these are confused and think replacing the outside belts is the same as the timing belt. The timing belt is inside the motor. If your vehicle is older than seven years, check to see if it has a timing belt. If so, make sure the timing belt has been replaced. Often times, this can save your motor.


When in doubt, Contact MY Automotive.

VOX MAGAZINE ARTICLE ABOUT MY AUTOMOTIVE

11/28/2013

VOX magazine did a great article about MY Automotive titled: MY Automotive focuses on European cars.

Mike Noel and Yuri Rozenblat specialize in European cars. Rozenblat’s fluency in three languages helps attract Eastern European clients.

According to a recent survey by Auto Inc. Magazine, the biggest concern of auto technicians is keeping up with technology. As cars are become more computerized, Noel says the technical component of repairing is now just as important as the mechanical component. Noel and Rozenblat take multiple classes a year through ACDelco, an automotive parts brand, to learn the new technology.

Thank you to VOX magazine for the great article.
