    I suspect my vtec of having failing CCT's. (I get quite a rattle, normally between 55-80 degrees Celsius on the coolant) this goes away when the engine is warmed up.

    Anyways I told my dealer that I need new CCT'S and they ordered 14510MCW003 & 14515MCW003. (tensioner blades) The part that everyone seems in the guides online to be replacing is 14520MCW003. (which is described as the lifter assembly)

    I'm just hoping that this is the correct parts that they have ordered! Can anyone offer an expert opinion?

    Cam chain tensioner? Wazzat?

    A typical symptom would be a knocking at idle that diminishes away as you increase the RPM.

    That's what mine is doing, I was going to get mine from the dealer too. I haven't been able to find any aftermarket ones.

    I can't answer your question, but am wondering how many miles / km you have on the engine.

    49,000 miles verging on 50k. The service history is all there but doesn't go into detail about what was done So I can't see if/when they've been replaced previously

    There is an alternative to replacing the tensioners. You can take them apart and add tension to the spring inside.

    It sounds like the spring is worn out to me. I've heard that this trick rarely works for more than a month, then you have to do the job again. I think I'll just look at the tensioner as a wear item every 30,000 miles or so. To each his own though.

    Asshole alert! (Me)

    Seems like RRW is posting only to promote his videos on YouTube, and is not necessarily an expert tech guy ..... a full time YouTuber......he's on both VFRD and VFRW....

    He s not interested to say here's my bikes and wanting to be part of the community and trade posts, and possibly befriend people......

    Go pound sand dude........

    You can get manual tensioners for about $60 each. If you think they are the culprit I would replace them.
    I’ve done it to a few bikes. CBR 1000, a couple Superhawks, a R6 to name a few. It better to replace it when it’s just a suspect than after it fails. I’m working on a Pioneer 700 that it failed on right now. $70 for the tensioner. Upwards of 2G for all of the damage caused.
