Post subject: | R53 Timing Chain Noise |
Hi All, I have a 2002 JCW with 180kms. It makes a noise at low revs, but high load (in 5th or 6th pulling up a hill) like a high pitch ticking that is not consistent and when you back off the throttle it drops away. it sometimes makes a little rattle on a cold morning also. I replaced the tensioner a few months back and it helped a bit but I wonder if the whole job needs doing. does this sound like timing chain? Thanks |

First noise from your description seems like pinging (engine knocking / pre detonation). Normally from having low octane or poor quality fuel or too much timing advance. It can cause big engine problems |

Definitely get it checked. As Tim suggested sounds like knocking, but with a modern car they normally have a “knock sensor” to automatically adjust timing and protect the motor from damage. Perhaps this is faulty? Sent from my iPhone using Tapatalk |

Thank you. yes, that may be the issue. I put standard fuel in last time I filled up due to not having high octane stuff at the pump. that could be the issue. Thanks |
