Why does my car make a tapping sound when I start up?

If a can of SeaFoam was fed into the engine it’s possible an exhaust leak would show up shortly as SeaFoam will cause fairly heavy smoke (normal) after running for a bit. As to the delayed start/ start on second attempt, that sounds like a loss of residual fuel pressure. The system should maintain pressure while the car is not being used.

When does the noise of the transmission go away?

The noise does varies with engine speed. When transmission is shifted to drive or reverse the noise goes completely away. Car runs fine except it has a little rough shift from 1 gear to 2nd gear during hard accelerations. Any idea of what might be wrong?

Why do I hear a noise when I put the car in gear?

The transmission should engage easily, and you should be able to drive without any effort. If you’re hearing loud noises when the car is put in gear, it could be one of several different problems depending on the type of noise in question and when exactly you’re hearing it. It may not even be related to the transmission.

When do you hear the tapping on a truck?

The tempo of the tapping is symmetric and speeds up as the rpm go up. Also you can hear the tapping if the truck is under load. The more load there is, the more noticeable the tapping is and the longer it takes to go away. ok4450 July 6, 2016, 2:42am #7
