Odd knocking sound at low rpm accelleration
I've always been the type to think that I take care of my toys, small to large; keep them tuned, well lubed, and clean. But one thing that's bothering me (that the dealer said was normal) is this knocking sound when accellerationg in a low gear at low rpm.
Here's an example: I have a corner that needs second gear to turn onto. It's got a bit of an incline at the beginning. Its exteremly prominent on this hill. Gear down to second, cut across oncoming lane and accellerate up and around onto road. So the speed is about 25 MPH, depending on how ballsy I feel for the day and if I can get across the lane without traffic interfering. So 25 MPH when I hit the base and start rolling on the throttle. As soon as I do, I hear a knock knock sound the same speed as the engine rpm.
It sounds like a lifter but I can't tell; I've never had a lifter go bad in any of my vehicles.
On top of that when rolling on the throttle from idle speed, there's a bit of a ping to the motor. Can especially be heard at a stop when setting up to take off. Just a really high pitch ping. This though doesn't last more than a split second. I've tried different grades of fuel from different stations but both ping and knock are always there.
Any other 1900 owners out there that can verify that this is normal, as the dealer tried to pass me?
Thanks in advance!
