I thought I’d resurrect this thread bc I have now changed my oil twice since posting last fall. I went to 5w-20 (to stay in the manufacturer’s alternate US spec), but it didn’t quiet things down. Today I went back to 0w-20 after putting 5k on the clock. I’ve heard the tapping noise all winter long during the transient time when the truck is warming up. First 30 seconds to min sound normal but then the tapping which comes in waves and cycles, progressively getting a bit louder until something kicks in and it goes away almost entirely. After the truck gets warm after 5 mins, it goes away and runs smooth.
Today, I had my oil changed today at the Toyota dealership and was able to speak with the tech mechanic that worked on my truck. He seemed like he knew what he was talking about more than others I’ve spoken to in the past. In short, he said this is very normal. I asked specifically if it was the tensioner, and he said no. He started to explain why, but I was impatient and cut him off to call his attention to the noise when it started tapping again. He told me how he has a 2012 sequoia himself, and that it’s much noisier on his truck. He said he went even thicker than 5w-30 to 10-30 and it really settled things down. He assured me after hearing it cycle a few times that it’s not uncommon and very normal.
I asked if he has worked on many LCs. He said no, bc they are pretty rare to come across, but that he has worked on plenty of sequoias (and me may have said tundras) and assured me this is not an issue.
I asked again about the tensioner and whether there is a risk of the chain jumping. He was polite but smiled and said no…. There’s nothing wrong with the truck. This after, he had just worked on a 2011 LC that happened to be there that had the power steering go out.
I had also taken it to a Toyota mechanic in the fall, but I don’t think he knew as much. Also, the clanking was as evident when I showed him bc we were indoors, so it came on and idled nice and smooth. He also looked the truck over and didn’t see anything amiss.
Long post, but thought I’d see if others out there agree that I should quit worrying about it and just realize it will be a bit noisy until I go to a thicker oil. I was ready to trade it in today bc I’ve had so much anxiety about this noise!
