Sound coming from the engine in 2000 rpm

Friends, my 2004 model 307 sw gasoline car has a voice I couldn't solve for 2 months. When I first start it in the morning there is 1-2 seconds and then it stops. (A sound like a click) Then, when the engine gets warm, this sound starts to come again. When the gas is loaded lightly, it starts to sound in 2000 cycles. There was a similar voice last year. Recirculation pump changed, sound stopped. I showed it to a master. "I suspect the beds," he said. I could not trust. I did not open the engine. I showed it to the Authorized Service. Manifolt is cracked. They said we will open the engine cover and look. Now I'm hesitating. Could it be from the circulation pump again?

The sound you mentioned seems to be related to the exhaust system. I experienced a similar malfunction, they said they were missing the manifolt right after, they did. it may be caused by a crack in the manifold, and if you do, it can be cut after it.

I'm leaving the car to the service tomorrow. Let's see, I hope it is manifold. If they are out of bed, a lot of expenses are waiting for us. Hayýrlýsý ..

My brother, take it to the service, the service has a parts warranty, but do not open it somewhere else.

I gave the car to the authorized service. First they said from the valves and they said we sent the valves to the contractor and got it done. I bought the car in 3 days. After I went 5 km, the same voice started to come again. I immediately took it back. They said we will look. They said they were from the main bed 1 day later. I received it 2 days later. They opened the engine from the bottom and changed the bed. The oil pump also changed as the oil indicator also glows. A total of 2,250 Charges came out with an air conditioner cost of approximately 750 TL. I have been using it for a month now. No problem
