I seem to have a small issue with my car, whilst im stood stationary I seen to get a knocking noise from the engine area that varys between every 5-15 seconds. When I hear the knock I can also feel it through the footwell it nearly seems like some sort of mechanical component knocking. If I rev the car up to 2,000rpm and hold it there for 10seconds and let off you can hear a vibrating noise and when the idle settles the knocking becomes more apparent (louder) for a short while then resides to the slight knocking I can feel. Has anybody else ever had a problem like this?
Im not sure if it is clutch/flywheel related or engine internal related?
Im worried that when I accelerate something is going to go pop :-(
