I had my 993 down at a bodyshop this morning , arranging to get the alloys refurbed. I'd chosen this particular bodyshop as he specialises in Porsches and has had recommendations from a number of 993 owners in recent times.
To the real point of the thread , he asked me if I'd had my rear chassis arms checked out... HUH!!? .. I'd not heard of a problem in this area , so he started showing me pics of work he'd done on about 4 different 993's.
Apparently , when sealer was applied at factory , one section was missed out and has become a haven for the tinworm , but can't be seen unless , firstly the rear PU is taken off , and then a side support to the rear chassis leg is removed. On each of the cars he's checked , it's been riddled with rust and only going to get worse, needs a new bit welded in and new chassis arms (sorry I don't know the exact term but I'll clarify with him in the coming days) need replacing , they cost £80 each (one for each side) from the friendly opc.
I'm getting him to strip my PU and have a look to see if this needs doing in my car . I've also asked him to take photos, so I'll keep y'all informed.
In the meantime , has anyone else heard of this phenomenon?? :nooo:

Well the upshot is ... Guards , take a bow , you're 100% correct.
It's the plate that supports the rear quarter panel , and somewhat the bumper thru the supports. Behind this plate and the chassis shields , lurks the mischief. The plate , and the shields need to be removed , work carried out to the chassis frame underneath , including stoneguard (well this is what my man does) , so there's no chance of the same damage being replicated in the future.
Ithink this image shows the offending area , with the shield and the plate showing...
