I've got a 87 22re turbo the idle is usually about 1400 every once in a while it'll drop to about a 1000 or just a touch under, where do i need to start?? also it's got about 20000 on a rebuild and it's started a neat trick of pooring blue smoke out the pipe at first start and even after 20 mins of drivin it smokes worse than my cummins and of course it only does it once in a long while, i pulled the turbo pipe out and below the breather tube inlet it's full of oil i need help i'm a diesel guy not to up on toyotas
