Car in question is a 07 Type-S 5AT with 65k kms.

Im getting an intermittent squeak noise from the engine, usually happens after spirited driving with lots of downshifting rev matching. It is a rev driven squeak so it follows the rpms, at idle it would be very quiet but anywhere from 1-2k its very loud.

After the car has a chance to cool down significantly it usually stops. The next morning cold start will have a brief squeak for a couple minutes then goes silent again like nothing was ever wrong. The problem doesn't seem to appear if i drive normally.

Solution? Drive normally right?

Did some searching already, found the TSB for ac bolts but that problem is supposed to apply to when it happens on cold starts, which it doesn't usually.

At 65k kms which is like 40k miles would it possibly a timing belt issue? Maybe replacing drive belt would help?

 

I had a tensioner issue not too long ago, give that a look. See if there is any wiggle room along the drive belt and the pulleys that the belt is on.

 

Would checking it hot or cold be better? It usually only happens when its hot but how do i check it if its hot

 

I also had a tensioner/idler pulley issue that caused a squeaking, but only at cold. It would go away after 5-10 minutes of driving, and longer in winter, it would not come back after flooring the car thats for sure...i'm doing my timing belt soon so i'll tough it out and change everything at the same time.
