Noise in the camshaft drive (3S-FE)
Since last autumn, my Kaldina "clattered", the sound is similar to the work of a diesel engine. Considering that I took it from the temporary storage warehouse, our handles did not go there and the option of an uncocked gear fell out logically. There was a gap in the valves or timing belt rollers. I started with valve measurements at two services, everything is OK and they say they checked "Gear is cocked" Yesterday I drove it to the last service station to replace the timing belt and other things (oil seals, rollers). After the replacement, to my regret, the sound has not changed. The sound is clearly coming from under the cover in the area of ​​​​the gears (now I know where they are located). I give the order to open the head cover - I ask how they checked the cocking of the gear - the answer is modest silence - remove the camshaft - the gear is cocked under my strict guidance (it is clear that they are doing this for the first time in their lives). They cocked with the camshaft removed, holding it in a vise (wrap with a cloth). There are two additional recesses (or holes), and so they didn’t find a key (like from a bicycle), they stuck a meth. cocked the pin and hand (locksmith), and I twisted the bolt (I was in a suit, only from the meeting). I think the shift should be about one tooth, and then, in theory, you will not have enough strength. When the gear is cocked, the threaded hole matches the other unthreaded hole. I don't think you need to pull too hard. All efforts are made within reason, and even I (an office worker) would have had enough strength. Be sure to remove the bolt after installation. Everything is going into place — and lo and behold, the engine WHISPERS. When the gear is cocked, the threaded hole matches the other unthreaded hole. I don't think you need to pull too hard. All efforts are made within reason, and even I (an office worker) would have had enough strength. Be sure to remove the bolt after installation.

For information, the sound was clattering and the operation of the engine is similar to a diesel. The second camshaft was not removed, there is no crap. In order, the cover is unscrewed - the clamps are unscrewed (which hold the camshaft 4 or 5, I don’t remember 2 bolts on each) and the camshaft that is closer to you is removed - the gear is cocked and everything is assembled in the reverse order, the cover and washers under the wells are smeared with sealant. And more labels (1 point on each gear, not to be confused with two) should match (be as close as possible to each other). When the gear is not cocked, the holes do not match (a little 2-3 mm.), On the outer gear (which is on your left) there is no thread, on the right there is a bolt for 8 or 10 (do not confuse the key with the thread size).
Bad! This is not the first time I see this! And I just have a clattering sound, in the camshaft cover! At first I thought the valves should be adjusted, but now xs))
I don't tickle! More precisely, it clicks, but these are nozzles, and the engine does not make the sounds of a diesel engine.

in general there is such ... not diesel, but noisier than we would like
Yes, when I went through the engine, I cocked the gear! It is noisy by itself, but not like a diesel engine!
OP and I'll note. Although I have 5S-FE, the question is just as relevant.
I have been thinking about climbing there for a long time, the tractor sound and tapping are also terribly annoying. I think the problem is the same. Well, I’m thinking of adjusting the Valve, I’ve already figured out where to get the adjusting washers, so that it’s not expensive. It seems to me that valve clearances were measured for this comrade in the same way as the gear platoon. Although it is easier to find these shims in Russia, hardly anyone wants to take on replacements.
Yes, find pucks! I really haven’t tried it yet, but it seems to be difficult to do it)))
I think to sharpen from the VAZ. The turner at work was told that it was feasible :)
Collective farming, but at $ 5 apiece, it seems like they draw on existentialism, what for I don’t need them)
I think it makes sense to climb up to see if the "symptoms" are the same. about the existential — I switched to 1001spare parts. There the prices are cheaper and there is less hemorrhoids with them.
It’s not enough to see, you need to try it))) Here I’ll change the head gasket, at the same time I’ll try to cock it!
It was like that, when replacing the valve, the guys, out of ignorance, did not cock the gears. The work was like that of a diesel engine. After cocking, the sound of the diesel engine disappeared. It was three years ago. Now there is a clattering sound from under the valve cover, after warming up it disappears. It already looks like a valve.
We have the same diesel engine on our sv41 (3s-fe) kamryukha, after replacing the Moscow time, rings and seals, the minder did six months ago, the other day he called, said about the diesel sound, he - that he probably forgot to cock, now my leg will heal, I'll go, it will be visible there.
