I am smelling the decidedly holiday season smell of roasting chestnuts, except in this case they’re roasting acorns from when this car was apparently parked under a tree.

This is a new one on me - any tips on where to look to clean the acorns out? Fresh air box in the front trunk?

Thanks!

Check the heater hose that goes from the flapper boxes to the opening in the longs.

I had critters get in there and make a nest inside the longs which resulted in a nice warm urine rodent smell and turned really aromatic when one of them died in there.

I bet that did!

Thanks Andy.

The little effers love nesting in the longs. I put my scope down there and then the vacuum to remove the nuts and the bones.

Yep. Shove a vacuum hose from the engine bay into the longs and blow out the heat exchangers.

Thanks gentlemen - super helpful as always!

I had a hotdog muffler stored in a shed. When I got it out to install it, I found that rodents had built a nest in it. I pulled out as much as I could, and used compressed air to clear more. When mounted on the car, upon start-up, even more nest material blew out.
Once it seemed clear, I went for a test drive. A guy pulled up next to me and said "nice car, what are you running in it, Bio diesel? Because your exhaust stinks!"
I laughed and continued my drive. It took getting the exhaust hot a few times before the odor went away.
