Valve cup

Hello friends, I was in trouble with the cups for a long time, the car was in summer, especially when I was driving the car, the sound of the sewing machine sounded, I changed the 16 cups 2 weeks ago, but if it is not as much as I used to say, this sound is going to happen. If I change the pump, it is interrupted or the sound oil filter has just changed.

my teacher might have a problem with the eccentric shaft slots. or there is a problem with the sentence setting. It may be possible that the oil pump is blocked If the oil channels are blocked, the pump may not be able to provide sufficient pressure.

Is it possible for my teacher to sound when the engine is cold or when it is hot. For example, is the sound of high cycles or idling.

Generally, the engine gets hot and the sound starts to idle, and when the gas presses, the frequency of the sound increases

If my teacher has a problem with lubrication, when the engine is cold, it will be harder to have less fluidity and the sound makes more. I think it makes better lubrication when the oil fluidity increases when it warms up. I also recommend you take a look at this link.

Thank you bro, thank you.
