I recently acquired a 1992 manual sc300 with 193000 miles, it drove home fine with no issues but now a day later it is making rough sounds on startup as well as producing a constant stream of light gray smoke from the exhaust. I was wondering has had similar experiences or knows what the most likely issue/issues might be? I have attached a sound recording of a cold start as well as a short video of the smoke. Also I dont know if it matters but it was my first time driving manual when I drove the car home so I might've been a little more rough on it than usual.
