just had my motor rebuilt 300 miles ago and also got a new turbo. while getting it tuned the head gasket blew. got a new head gasket put in and it started smoking really bad.(blue smoke) got told it was from when my turbo blew it coated the inside of my exhaust with oil. when i pulled off my exhaust from the back of the turbo and started it up it took a second but then it started pushing oil into the exhaust from the hotside of the turbo........ so it wasnt the exhaust its coming from the turbo..... i also pulled my spark plugs and there was oil on the top of all my spark plugs. when they replaced my head gasket though they had my head decked and said there was no damage to any of my cylinder walls or anything like that! i was wondering if the turbo seals being blown would make oil come out the exhaust and go back on top of the cylinder or is there something else im missing!?
