I did pay an arm and a leg to have the VCT replaced in December. The noise did not return over the winter.

Recently, I decided to look up past receipts and check what grade of engine oil the dealer used for oil change. To my surprise, the dealership used 5w20 instead of 0w20 as the manual recommends. Ow20 is thinner at cold temperature. I wonder if that's was the problem.

No that was not the problem. 0w and 5w are very similar. I'd be very upset about having the VTC replaced with a high out if pocket cost. As said a thousand times, it doesn't fix the problem and it still grinds when starting when cold on occasion.

good lluck
Hey TexasHonda, have you continued with this suggestion? I'm curious if you have enough data points now to suggest whether this helps or not.

Thanks!

No, my actuator rattle has disappeared ( synthetic oil change?). I have no way to know if the suggestion will help.

good luck

I've been strictly using 0w-20 synthetic oil (blend once, but not currently), and the past couple of weeks the grind has been happening almost daily; sometimes even twice a day. Can't quite remember what I have in there right now... might be Castrol (black jug). Maybe I should do an earlier oil change and switch back to a different oil I've used previously and see if that helps.

Hello!

VTC actuator. Had this problem on a brand new TSX 09. So i think it's a flaw by design. I've replaced it once and made it on the first startup lol. Once temps get under 0c (i'm in canada) it does it from times to times. Been told by Acura it's nothing serious.

Good day!

I’m experiencing this intermittently with my 2013 TSX SE with 60,000 miles on the ODO. Only seems to be an issue when it is exceptionally cold, and when the car sits “outside” for an extended period of time (airport parking garage, most commonly). The grinding noise disappears very quickly, and only happens at first startup. Vehicle is meticulously maintained and oil is changed with Mobil 1 synthetic 0W-20 every 5000 miles. I hope no real damage is being done to the car with this!

No there is not any damage being done to the car, just sounds terrible.

How do you know this to be true?

My Mechanic used a better oil filter when doing my oil change and it seemed to decrease the frequency of the grinding noise. I used to hear it on almost every start up but now itís down to like 50%

What were you using before vs now? I've always used the mobile 1 filter. Didn't hear it too much this winter.

Was directed here by TexasHonda. I just bought a 2012 wagon and have the noise as well. Didn't make the noise when I test drove it tho. I'm guessing the dealer was aware and had the car started and ready before I got there. It happens when the car is sitting for a cold startup so how couldn't they have known? They offered to fix it for me but I'd have to return to that dealership which is 5 hours away and just isn't an option for me at this point. I've been in contact with Acura customer service and after telling me to have it diagnosed at an Acura dealership they said they will be in contact with me on whether this will be covered full cost or partial cost. Bought the car with 69,942 and driving it home 5 hours away of course put me over the factory powertrain warranty. I called them to see if they would make an exception out of good faith but won't know the outcome till Wednesday.

I've also been asking my mechanic (a Honda tech) about it as well and he said he is familiar with this problem. Says the same that others have with oil leaking from the actuator and has to prime itself back up on start up. He said I should to the chain and tensioner as well but I just got off the phone with him and he said that he thought I had higher miles (120k+) which I do not. I asked if he had any success stories about these repairs and he said that they do them quite often and has done 3 this month and doesn't see a problem after it's done. He said the parts are covered up to 6 months too.

Also, a friend of mine just sold his 1st gen TSX and said he was experiencing the same problem just before he started looking for a new car. He thought it was some kind of bearing. The guy that bought it (also a Honda tech lol) said it probably needed a new tensioner etc. Probably knew it was the actuator and considering he had over 200k he probably knew the chain was stretched.

My 02 RSX had about 225k before the chain stretched so much and got a cam position code. Chain, tensioner, guides and actuator all done and she's still going.

2012 TSX Wagon with 50K dropping off tonight at the dealer for this. CPO Powertrain warranty expires next month so timing is excellent.
