Valve tick at idle
Ive got a 2000 a4 1.8t quattro and i have valve tick at idle. Is this normal. I hate the noise, its so loud. What can i do to stop it. Something easy or am i looking at changing springs and retainers, or?

Symptoms:
When the engine is under load, it ticks for about the first 2-3 minutes of driving.
If I start the car from cold, and let it run for a few minutes, the ticking never happens.
The ticking also never happens at idle, even when cold. It only happens when under load. I've even applied the brakes, put it in Drive and gave it a little gas. It ticked when I did that, but if I put it into Park and bring up the RPMs, it doesn't do it.
I've noticed that when I start it from cold, and drive away, if I go easy on the gas (grandma driving) it doesn't tick. But even moving at 20MPH and giving it a little more gas to accelerate it starts to tick.
I DO know that the last time the oil was changed (by the previous owner, not me) it was done with mineral oil 10w-30.
I'm going to change the oil on November 1st.
Per your recommendation on a different oil, what do you run? I'll probably buy Mobil 1, but what weight?

Try changing the oil, I had a small tick once and it got me worried. After I changed the oil it went away. I change my oil every 5k miles and I went a little over and it started to make the noise. I've read it could the lifters making the noise.

yea its probably sticky lifters, these cars are prone to crap build up in the oil passages, particularly the pickup tube. throw half a can of seafoam in there and drive around for 100 miles. then right before you change the oil throw the other half a can of seafoam in there and go for a quick drive around the block, dont beat on the car with the seafoam in the engine, then let the car idle for like 10 minuits. then change the oil. that should greatly reduce the noise. i would also use 0w40 fully synthetic for some more protection. if that doesnt help check your cam chain tensioner just to make sure thats not whats making the noise.
