5th & 6th Generation (2002-2006 & 2007-2011)Toyota Camry Discussion for years: 2002-2006 & 2007-2011
Topics of discussion range from fuel economy, safety, modifications, performance all involving America's favorite family car, the Toyota Camry.
Greatings, I recently purchased a 2008 Camry 4cyl with 50k miles on it, the car runs great however on colder mornings (near or below freezing) there seems to be a ticking sound coming from the engine bay. The noise matches engine rpm, it will disapear once the car has reached operating temps.
Ive poked around the forum a bit for "camry ticking or clicking when cold" and have found a few threads saying their toyota dealership told them it was normal and that even new camrys do the same noise when cold.
Yeah I bought it at a toyota dealer its a "toyota certified" vehicle, with proof of maintence of the previous owner. The oil change was done before the vehicle was delivered to me.
On cool mornings it's not uncommon to hear a little valve noise. It should not be excessive though. Some find that using synthetic oil makes a difference. It really should not be noticeable from inside the vehicle...
If it keeps up even when warmed, that's when you get issues. it could be a lifter not getting any oil.

I was under the impression Toyota used 5w20 fully synthetic oil?

As stated it will only do it for a minute or so until the engine gets to normal temps, and only when the temp is near or below freezing, we had a couple mornings last week below freezing and thats when i first noticed it, this weekend however it was slightly warmer and had no noise what so ever.
You have to remember that you have sixteen cam lobes actuating sixteen lifters which actuate the valves. Every interface has a designed in clearance. Even a good 0W-20 oil is slow to flow at the outside temperatures you noted. I am not sure what the valve clearance is on your Camry but would guess it's probably .008 for the intakes and .012 for the exhaust. When you let a car sit outside in cold weather, these clearances increase and at start-up you will hear valve noise. If the clatter subsides at operating temperature you probably have nothing the worry about. My first car had solid lifters with adjustable rocker clearances and that car was very noisy compared to what I drive now. Regards
