few questions

hello...first of all, I have an exhaust leak and im not very familiar with what is what down there so i was wondering if anyone knew where I could find a diagram of the underside of a 1991 3000gt SL so I could find out where the leak is coming from exactly. Also all of my gauge lights dont work, speedometer, battery, oil pressure etc. I checked the fuses and their fine, if anyone has any insight as to how this could be fixed that would be awesome. Thanks a lot.

Dash lights being out means taillights are out. Check the fuses under the hood. There is a fuse marked tail.

The exhaust is probably leaking at the flex pipe. The flex pipe is probably borke because you have worn motor mounts.

well how can i be sure that is the flex pipe..and what is it that makes u say i have worn motor mounts?

Common problems

so in regards to fixing the exhaust leak what would be the best way to go about it considering this is the second time in a few years that it has busted?

If its the second time then that definitely says worn morot mounts. Get new mounts and it wont happen again,.
