Engine rattling at idle
 

So I've been boosted for about 2000 miles, everything is going great but I notice after 3 or 4 hard pulls over 6000 rpm when the car is idle it sounds like some serious engine rattling going on. Obviously the engine is hot but is this something I should worry about?

I'd take it to a mechanic to see what he thinks.

engine oil temps shouldn't matter whether or not you have a rattle at idle...

Can you focus where exactly the rattling is coming from?

Maybe rattle isent a good term to use but it basically sounds like metal grinding and the engine is about to jump out of the car. Oil pressure goes down but after a few seaconds it comes back up and sound stops. I'm getting most of my fluids changed and an oil cooler installed today so I'll ask them. I just assumed it was the engine trying to cool off or something

Can you post a video of this??

Clutch pedal in or out make a difference at all?

Well they said the oil was getting too hot, and I'm inclined to believe it because the oil cooler solved the problem. So for now all is well. I'll just have to see if this happens during a track day. Hopefully because I put the cooler in front of my intercooler it won't heat soak.
