Hi everyone hope im doing this right. 92 sc400 122000 miles. Yesterday and today after coming home i noticed smoke coming from under the hood on passengers side near the firewall and also smelled something like rubber burning. I popped the hood and looked where the smoke was coming from . Its this big rubber looking thing attached to the the upper firewall passengerside. I peeled back the rubber part almost like a boot? a lil and actually could see that it looked red like something was heating up. i guess that explains the smoke and smell lol. My question does anyone know what it is? All my gauges etc stayed in normal mode and car drove fine . i didnt notice until i saw the smoke. It seems to happen only after i drive at high speeds above 50mph. thanks so much if anyone can help

 

sounds like wiring harness take pics so we can see it ... could be bad situation burn up all your wiring..

 

Hi thanks for the reply. I think your right . What are the chances that oil might be getting onto the wire harness . And could that be what im smelling is oil burning. I think either way im screwed lol. I took pics but cant seem to upload them ill try again thanks so much for your help.

 

i hope u can see them ? smoke comes from the back of that big rubber thing

 

After freaking out. Figured out it was oil leaking from valve cover onto the cat lol
