Knocking sound under the hood for a 2007 Suzuki XL-7 with 105 K on it.
4 different shops assured my that my XL-7 needed timing chains and tentioners
changed. I paid $1600 the have new ones put in and the problem is exactly the same
i.e. Knocking sound + check engine on. Any ideas what the problem may be?
First thing to do is scan the computer and get the trouble code(s). That'll point us in the right direction. Most auto parts stores will do it for free. Does it only knock on acceleration? Or all the time? Please post those trouble code(s) when you get them. HTH. -Jim
Hi, I am sorry; I should have given the codes. They are P0008 and P0333. Because we do not have Suzuki dealers in Wisconsin, and I was told that the Suzuki XL-7 2007 is a Chevy engine; I took it to two Chevy dealers and Firstone. Plus I spoke over the phone with a Suzuki service shop in Illinois and all previous told me the same thins i.e. the codes and the knocking sound all signs of Timing Chains and tentioners gone bad. To answer your question: the knocking sound is present whether idling or moving. Thank you for taking the time to help. P.S. Now that I have changed the timing chains, I am going for the rest one thing at a time: spark plugs then water pump then alternator then ???? until hopefully I get to the bottom of it. I am hoping it is not a piston or something like that :-( Ahmed.
Yes, you are correct. In simplest terms code P0008 is telling us that the camshafts are out of position. Most likely due to wear of the timing chains or improperly installed timing chains or components directly related to the timing chains. Code P0333 is high voltage on knock sensor number 2. The most common cause of this code is a faulty knock sensor or the wiring going to it is damaged or shorted. HTH. -Jim
Thank you for your input.
You're welcome. Glad to help. -Jim
