It sounds like it's coming from the engine.. not really from the belts or fan.

I had my timing belt done by a fellow audiworlder and had the car completely apart.

I am hoping to god that we just forgot to tighten something but not sure why it is making that noise.

The car is smooth as heck, no problem with mileage/smells. I guess what I am trying to say is nothing else is out of the ordinary, just this noise.

Almost sounds like its knocking but I only put 93 in my car, never ever put anyting lower.

Any help would be greatly apreciated.

Check valves can be replace, although not too cheap.

cam tensioner, maybe run thicker oil

could just be the tick of fuel injectors, listen near the fuel rail

I have been ready to ask this question.
I have a clunk, cluck clunk noise on start up. I had my ear on the back of the valve cover and i can hear the noise coming from the cam tensioner. When i did my valve cover gasket, i took a look at it and it was clean, the plastic guide the chain rides on was looking like new. I pressed on it and the chain is tight....etc.
I guess i have a noise cam tensioner????. Im running 0w-40, should i be looking at 5w-50/10w-50/15w50?????
