Get ready for a long post. I have a 1989 Volvo 760 wagon. Keep in mind, that I did have some mods installed on this thing prior, but since the problems have started, I have removed them all. This is my DD, so its extremely crucial that this thing has minimal downtime, and excellent reliability. PROBLEM #1: The old turbo went out, and so I replaced it with a new one that is stock and freshly rebuilt. I'm almost positive the turbo is operating properly. It spools fine, and doesn't bind up or anything. The problem is, the old turbo was in there for awhile when it wasn't doing so well. I was looking at the dipstick today and on the bottom of the dipstick there is this gritty, greyish colored gross shit. It definitely has metal shavings in it, which makes me think bearing material either from the old turbo, or from the engine. Thats the first problem. PROBLEM #2: The car is smoking like crazy out of the exhaust. It is burning oil and coolant. Its bad, I go through a quart a week and have to refill the coolant about twice a week, just to keep it at the minimum level. Its really bad, and it smells like utter ass. PROBLEM #3: After driving the car for about 10 minutes I got out to fill it with oil. When I remove the oil cap, smoke comes out. Its blue in color, and definitely smells like burning oil. These are the two main problems that I have. I am looking for second opinions. I think its a head gasket, but I'm not really sure. It could be a number of things, but I'm thinking the main problem is the head gasket. Sorry for the long read. I tried to make it detailed so maybe I could get some second opinions. Any help at all is greatly appreciated.
