I have a ticking that lasts about 2 seconds upon start up after sitting for long period (couple hours), and when driving I hear it at approx. 2500 RPM while shifting through the gears. I took it to mechanic who said timing chain was the cause. So had timing chain, tensioner, water pump replaced. Took it for test drive afterwards and no change to noise issue. They are now stating carbon deposits is the cause and advise I put fuel cleaner in every 2-3 fill ups as well as engine treatment every 3-4 oil changes. This makes me think they don't have a clue as this presents a timing issue, fuel issue and oil issue! I have already paid $910 and would like to know what is causing the problem verse continuing to sink money while they attempt to figure this out.
Do you

The symptoms indicate the noise is dependant on oil pressure. This could mean something like the timing chain is too loose, the hydraulic tensioner is draining off when parked or there just isn't enough oil pressure.

Did they change the tensioner and any plastic guides when they did the chain.

Yes, they stated they replaced the tensioner and guides. It only lasts about 2 seconds when I start, and I only hear it in range of approximately 2300-3000 RPMs.

Not my style. Specially since it resembles a "knocking lifter" type noise. And only started about 2 months ago. I've had the car for 5 years and it didn't have it when I bought it, so why now?

You could have a single weak lifter or any number of other possibilities but you'll likely spend a whole lot of money trying to pinpoint it when you can just wait till it gets worse.

Personally, I wouldn't waste my money.
