So i have a 200i scion xd with 92k, when i start it cold it makes a noise after turning over like something is hitting(about 7-10 knocks). Now it only does it on cold starts. Once the engine has been running and i try to start again it wont make the noise. Does anyone have any idea what this could be, or is it a common problem with this make and year?
Thanks

Im assuming so since i bought it from a large reputable dealer. And if it was the wrong viscosity it would have other affects than just a noise cold start. But thanks for the response.
Have the oil pressure checked. I would try changing the oil and filter and try using a synthetic oil to see if it helps. It may be that the oil is taking a little while to circulate throughout the engine and that is why you hear the knocking on cold start up.

It could be but only if it was like 20w 50 and it was below freezing when you tried to start it. But even then it would have to be a first time start. With higher viscosity oils, once the oil circulates through the system it stays coated there even after the engine is cold. For example, the Lucas oil additive it very very thick and states that this the benefit of using such a thick additive, it “prevents wear on cold starts” by coating the engine. Thicker oil coats the engine better, a first time start may cause lack of lubrication though.
It would greatly help if you provided a video of the noise at start up, we could then make a much more accurate diagnosis.
found a TSB on your vehicle.scroll to the bottom of page.
Toyota knows about it.I put another link for a possible fix.
Don’t know how true it is.Have you called toyota?http://www.cityscope.net/~daryl/tsb.html

Good job C man. To me it doesn’t sound like a bottom end noise, its a “brief rattle”.
Looks like not a very uncommon problem for the Toyota’s.
Here’s a video from a completely different person with the same noise and the same engine:
