Water ingress via air intake plenum chamber

[408VIKING]

I have the same grill mech on my 408. Has to be the original.

Most damage (rust) on my car is on LHS of firewall. See pictures.

The sealant was in good shape (soft) and the where no signs of leakage between plenum chamber and fire wall. The only possibility I can see on my car is at the top left corner, where it´s attached with sealant only.

Thanks for the photos Per. I suspect very few people have seen a 408 looking like that. It's interesting to see how it differs from the 411.

Any chance you could post a couple of photos from further back ? (not so close-up, so that those of us who are not familiar with a bare 408 chassis can get a better understanding of what we are looking at).

Regards,
Kevin
