    You having problem with VTC actuator on cam, take back to dealership and complain. They don't like messing with it since requiring opening engine and that not good for you either. Google vtc actuator problem, and you will see. This think can mess up your engine. Every fourth, fifth K24 engine have same issue some develop early some later on.....

    WOW! Followed your excellent advice. I found fragments of a TSB. If on ISIS you click on the picture to HEAR an example of the engine rattle [I don't have ISIS access]. But, here is the access to help others in my dilemma:

    [Honda] Procedure to pinpoint the problem---
    1. Allow the oil to drain from the VTC system by not starting the engine for at least 6 hours.
    2. Start the cold engine, and immediately listen for a loud rattle:
    Do you hear a loud rattle that lasts about 2 seconds?
    ---

    This seems to precisely nail the problem. Bulletin Number: SB-09-010 HONDA: ENGINE HAS A LOUD RATTLING NOISE AT A COLD START UP. *PE UPDATED 11/5/12.



    PassatB6-How did you come to know how often K24 engines have this problem, unless you are a Master Mechanic, and from your nickname I would surmise you worked on VW's at some point. In either event, THANK YOU!!!!!!!!!!!

    Yea I'm more in to euros, since I was born there. I'm very familiar with K24 engines, but I'm not mechanic, just enthusiast

    As others have said, you need to take it to the dealer and have them fix it. I don't know if your dealer is the same as mine but they won't do anything unless they can recreate the issue. With the warmer weather here, there were not able to recreate the problem and I left my car with them from saturday to wednesday. Of course the noise happens this morning when I'm heading to work. It got cold here again in the northeast. So, I'm off to the dealer again tonight and leaving my CRV there so they can hopefully create the grinding noise. I even showed them a video of me catching it on my iPhone but they said their tech has to hear it for themselves.

    Good luck.

    There is not much to do here, except to replace defective VTC, and I would trust only reputable dealer for this kind of work. Anyway you can prevent cranking time when starting your crv. Since Hondas have very weak batterys, it takes longer for starter to start engine. By replacing battery with more crank amps, and use thicker oil, will help little but your VTC will be still defective. Problem with honda and their delaers are they would not admit having problems here, but they are very aware of this. Another problem is even when VTC actuator is replaced after some time new one may start rattle

    Why do you think Honda's have very weak batteries?
    As compared to what?

    And thicker oil is going to make it more difficult for the engine to turn over, which doesn't help with the situation.
    I would suggest that people only use the oil type and viscosity that is recommend by Honda.

    I don't think my friend. It's fact. What cold crank amps crv battery have...? I don,t know 'till i check, but i don't think is more than 400 at most. Average medium size vehicles have cca500. My lawnmower have almost 400cca . And when you live in colder climates this matter a lot.
    For oil: k24z engines are made from year '03-04 and back then oil spec was 5-30. Since than k24 engine didn't change much internally or externally. Since this engine is low friction honda recommend 0-20 viscosity oil for lower fuel consumption. But this engine can run 5-20 easy.

    No, at best it's your personal opinion, and is more likely just anecdotal evidence. I don't remember seeing any widespread reports of starting problems with Honda engines, nor do I remember any published reviews that were critical of the CCA rating for the batteries that come standard in Honda vehicles.

    Do you have any sources you can share to support your opinion about Honda selling vehicles with undersized batteries?


    As for the change in the oil Honda recommends for the CR-V, I agree that it probably had more to do with CAFE standards than anything else. But that's just a guess on my part.
    And my point was that if you switched to a more viscous oil that would make the engine even harder to start in cold weather, which disagrees with the point I think you were trying to make about thicker oil making the engine easier to start.
