My car engine is knocking. I had it fixed but i recently still here it knocking.

What is your question?

I drive my car long distances about 100+ when I noticed the noise. I took my car to the shop and they told me it was the blow out bearing. so they replaced that and got a new clutch kit. -------------------------------------------------------- [125,000 mile on the gauge.] [just had the oil changed 3 weeks ago] Now about a couple of months later I drive over 100+ miles and I stop at a gas station and turn the car off. When I come back out and start my car. I hear the loud knocking again in idling state. I wait 5 minutes but it continues to knock. I decided to keep driving and driving 25 mph it continues. When I get on the highway, 4 gear the knocking stops. When I arrive at the next town 70+ miles I don't hear the knocking. When I press the clutch in the knock doesn't stop, but changes into a different knocking (nothing worse or better, but you can tell).
