SILVER Star
Have had a wet driver side foot well for a while, starting diagnosis. Thought it was leaky roof gutter, but didn't stop with temporarily covering the gutter, and upon further investigation it seems much more involved. It hasn't been driven in several years (that's another activity) but the water entry happens with every rain storm.
The staining on the firewall insulation pad in this photo is right below the clutch pedal, but there is no staining or streaks anywhere above the pad, on any hardware or bracket or underside of the air plenum. No rust seen anywhere up there, including lying on my back, head on and under the pedals, with lots of flashlights.
The firewall pad seems pressed under the pedal brackets, can't pull it out just as shown, but it's definitely wet behind. Here are the stains from another angle.
Floorboard
Closeup of clutch master cylinder.
The fender is off, and there's minimal to no seam sealer on the inside seams as is common. I'll rustrproof and seal that up (blue arrows.) The horizontal seam behind the pedals (green arrow) has sealer and it's in good shape, but I'll but another layer of sealer on top of it. But I don't think the inside seams are the source of the below clutch pedal leak. I've blown out the intake air plenum on the driver side, looked and felt around inside and even tried an inspection camera, but everything feels fine, and I don't see a spec of rust. Granted it's hard to really feel under brackets like the hood hinge or wiper arm.
Ideas from anyone? Other things to check? There is no visible exterior rust at the base of the windshield, and the molding looks intact with no cracking, but is old. Again, from the inside there are no signs of water entry above the clutch pedal staining. Maybe I should pull the cluster for another angle to look?
Thanks for any input, ideas, suggestions, past experiences! RJ
