Short of a complete engine rebuild, you could try a heavier viscosity synthetic oil. However, this is just a temporary fix at best. If you are hearing excessive lifter/rod noise, the engine is in need of major service.

2004 Nissan Altima 2.5 SE When I start it up it makes a knocking noise and is getting worse It's not a valve clicking noise but when I drive it it also makes the same noise when no torque while drivin?

It sounds like a connecting rod bearing going out. The only fix it to have the motor rebuilt before it goes out. If you wait until the engine blows you will have to buy another engine because of the damage that will be done.

Pontiac grand am and it is knocking at the back of the motor what could be wrong?

Internal knocking inside the engine is almost always a sign of worn bearings. Crankshsft, or rod bearing would be my guess. The fix, if it is internal, is overhaul. Before opening it up, make sure the knocking is indeed coming from inside the engine.


What can i do to stop that knocking sound coming from your car it happens when i drive or have the car on?

Usually when a car is making a knocking noise it is a very bad thing, which usually leads to engine failure and throwing a rod. I've had this same problem with my intrepid and was able to fix this by replacing a worn bearing on the crank. This is a deep engine job so make sure you keep track of your parts and do it safe and plan to spend 4+ hours on it.


What would cause a constant knocking noise in a suzuki grand vitara?

I have found that the noise that you are hearing are due to a belt adjustment that your car needs to have done - that is if you have a 2006-2008. Mine is making that noise but the dealer that I got it from are having a hard time reading the tsb on it so that they can properly fix the noise.
