So i was a little stuck in a sinkhole trying to get out with my gehl turbo diesel skid and for some reason the throttle got stuck it just revved like crazy and tons of bad smelling smoke came out the exhaust for 15 seconds then the engine died. I tried restarting it but it was still hot and sounded pretty bad. Actually getting some help to get it unstuck without running it but can someone give me an idea of all the things that could have happened to the engine etc and possible costs involved? I have no experience with diesels. Thanks
