ok so i have a decent time line for my motori just finished my rb25det swap in my s13 last weekend. car has been running like a champ for 3-4 days with absalutely no problems.i was driving it not "mashin" or driving it hard just cruzing up a not to steep hill when i noteced in my rear veiw mirror that i started to puff little clouds of white smoke in between shifts. car has lost no power and is not acting funny.pulled over to check everything out and it all dose and thers nothing visable its not leaking or anythingso with my uncles house just a few blocks away i drive to his house and its still doing it but the clouds ar getting bigger and bigger. i started to get on it a little bit to test it and when on it ther was no smoke except in between shifts. about a block from his house i started to get smoke from the engine bay so i finaly stopped for good i poped my hood and my dipstick had blown out of my block and blew oil all over my engine bay to make things worst. i checked my oil level i still had decent amount of oil i checked my water it still perfectly clean and not over heating.i tryed starting her up and she idles perferct with no noise or misfire. little smoke on idle but clears up after a few mins but once reved up more burrning oil and smoke i started leaking a decent amount oil from my turboelbow/ downpipe flange and from my downpipe to car flange witch tells me somting is leaking alot of oil. i took my ic pipes off im geting a decent amount of oil running threw them and in my intercooler all the way up to my intake. i thought it could be my pcv valve but it seemes to be working.could my turbo seals went out? compression ring? im gona get a compression tester real soon and test my cylinders what could cause this chain of events ?? im at a loss. i dont know where to start.. she starts and idles and the smoke clears up but now has no power

Your on the right track, Ill bet turbo seals if its leaking from around your downpipe flange area.

if it is my turbo would it cause my dip stick to blow out like that?and if it blew my dipstick out would it build enough pressure to blow out other seals aswell?
