Fumes in Cabin, very warm under dash - '99 Disco I

Hi All,

Fairly new disco owner here. Have a 99 Disco I - love the truck overall.

I've been noticing a toxicy, fumey smell in the cabin. I recently had the valve cover gasket replaced because of some oil leakage on the exhaust manifold (hoping that this would reduce the smell) but I still smell it...

I've noticed that right under the dash, below the AC / heater controls, it just feels "hot" all the time. Is this normal?

I'm wondering if there is some leak coming through the back of the engine somehow?

I'm looking for guidance on where to start or what might be wrong.

Thank you!

Boone

Remove the glove box and inspect for burning wires. You have a wiring and battery issue. It's ether coming from all those wires behind the glovebox or your heater matrix and if you don't get it fixed soon this is gonna happen

When wires burn off their insulation it makes a very pungent and nasty smell.

I doubt that your disco will burn down lol, but it will very likely turn into an expensive problem if 12v leads short to resistorized data wires.

Pop the hood and shine a spotlight down the firewall, and maybe around the tranny tunnel from underneath. If you don’t see a gaping hole, or smell the smell, let’s consider it electrical.

Pop off all of your easily accessible dash/console panels and shine an IR thermometer at the various cable looms in your hot zone for a clue.

Yikes - thanks for the advice. I'll get the glove box out and take a look - that would be a serious problem....

Any recommendations for repairs / guides?

Thanks

Well, found the source. Used some sea foam and immediately found the leak in the exhaust manifold - need to inspect it now and see if it's loose bolts or a crack.

Good job on finding that, but how is the exhaust leak getting in the cabin and making your dash hot?

I assume it's leaking into the cabin via leaky seals, or coming in through the outside air venting system?

Re: hot under the dash - I think that's unrelated, and potentially still an issue so will try to tackle that one next.

Does anyone have a meaningful link to torque specs for the exhaust manifold / collector?

Thanks

Boone

that's a fair point... my wife's C300 had a few loose bolts on the valve cover and was weeping oil onto the headers.
could only smell it inside the car when the fresh air was on.
