Hello. I have a Mazde 2 2003-2007 with a diesel engine. In February my car skidded and rolled over. The engine was flooded. It has been cleaned, but while driving at higher revs, since I picked it up, you can hear a whistle coming from the engine. The car does not weaken when accelerating. What...

Only organoleptically you will find where the whistle is. Eat to a recommended specialist.

As suggested by the colleague above. Invite someone to help you to start the engine and increase the revs, while you (after opening the hood) have to listen to where the whistle is coming from. Depending on the place where the whistle comes from and the noise level, you can deduce what is wrong with the engine. This can be, for example, a leaky interkulator hose, a worn turbine, an accessory belt, seized timing rollers or alternator bearings.

It has been cleaned, but while driving at higher revs, since I picked it up, you can hear a whistle coming from the engine. The car does not weaken when accelerating. What could be causing this?
