Hi everyone. I'm new the RX-7 culture and hope someone can help me. I just picked up a '93 silver on red touring with 45,000 miles that drives great(a little more loose in the rear than my Z), shifts well, and is very fast. One problem...there is a small oil leak by the turbos and when the car gets hot it gets on the exhaust and makes a lot of smoke. I don't even know where to start, and there is hardly any one around here who will even look at the car much less who knows anything about it. I have been told that the oil feed and return lines are made of rubber(seems kind of stupid) and crack from the heat. My problem now is that the gentleman who is willing to look at it needs to know what line specifically to look for. If anyone could give me some advice I would really appriciate it. Or if anyone knows of a good place in the area(I'd go to Chicago if need be).
Thank You,
Eli

Check the oil return line gaskets (coming from each turbo to the oil pan) check the I think they are called oil metering lines they are probably rubber they run all around down there. Also check the oil lines giving the turbos oil. It is one line that connects by the air pump and then splits and goes to each of the turbos they have gaskets too. Best thing to do is remove all the oil, make it spotless, then drive for a bit and see where the oil comes from.
Hope it helps

If you still can't find the leak, there is a dye that you can put into your oil mix. It will help you find the leak and is safe for the engine. Some dye come with a UV light that makes the lead glow. Search for 'oil return line' or 'leak' on this forum. I think someone posted a picture of the location a while back.
