    Rattle noise when cold start engine??

    When I start my 2003 Range rover in the morning from sitting all night I hear a Rattling sound when the engine turns over, I'm wondering if anyone else has this or knows what it is?? Im guessing it needs a tune up but not sure. Also the car has some humming sound and some vibrations that drop the rpms around 30 to 50MPH Im guessing its the torque converter issue so I've been told the torque converter is locking up and operating incorrectly. Thank you for any help

    I don't know about the rattle, but I had the same humming noise which effects the rpm. I had a radiator flush and filter changed and the noise stopped for a couple of days. The noise came back but at different rpm levels and it's not as bad. Someone suspected a torque converter but I guess well see what breaks to really find out.

    Which engine have you got?

    If it's the 4.4 BMW M62 then it's fairly normal for it to rattle for a few seconds until the oil reaches the heads.

    It's not the heads, it's the VANOS cam phaser system losing oil and rattling on start up. A search on VANOS on this forum will give you a lot of information. It is not generally considered harmful to the engine.

    Yes i have this same issue also and it sucked I hope its not the TC but its a high possibly and some times the car shakes a little before it starts the noise the humming buzzing noise so im thinking its the TC locking up Im going to start saving for a new trans and TC now because I have a feeling thats the issue, why do you think it stoped the the radiator flush? does it have anything to do with antifreeze flow? i wouldn't think it did.

    I will definitely research this , does it have any known issues that will come about from this? can this be prevented? Thank you for your response.

    I have noticed the same noise when my engine starts. Sometimes it it very loud and sometimes you can barely hear it. Even so, it doesn't sound right and it makes me cringe every time it happens. Glad to hear I'm not the only one experiencing this issue.

    It generally isn't an issue.

    Just make sure you use the correct Oil and change it every 6000 miles / 6 months.
