There's plenty of threads around with similar sort of issues and I read through them but i couldn't find one with exactly the same symptoms.
I replaced the water pump in my VP about a week and a half ago and there were no leaks/car was running well and not too hot.
I drove it to work the other day; and when I started it after work thats when I noticed the knocking sound coming from the engine.
I did an oil change and replaced the filter with a Ryco one but it doesn't seem to have fixed the problem.
The sound only occurs when the engine is idling, but it does it in all the gears, including Park. It's sort of a metallic knock but not tinny it sounds a bit like a rattle even.
Once I begin to accelerate the sound goes away and I'm pretty sure it's not just being drowned out, because I've had the radio off/windows down listening for it, It doesn't sound like it's getting worse but I can't imagine its great for the engine to be driving round if there's something wrong.
Any help/advice would be greatly appreciated as I'd rather not have to get the engine taken apart/pay for the labour for that if there are other possible issues that are causing the noise.
cheers
