Guys I just picked up an 85 Targa ROW car. It is in ok shape. I plan on a resto this winter. I picked up the car form a customer at our shop. He bought it over a year ago for 12K and never really used the car. The fresh air motor caught fire and melted the intake. The transmission is a little funny, I suspect syncronizers. He got fed up with the car and brought it into the shop and said he wasn't coming back for it. I picked it up for 2K. I know the tail is not stock. I have serviced it and plan on having fun with it for the summer. Now to my question. I have an oil leak at the vacuum valve above the oil tank. What is that valve?
