yea i got both mine redone at cr turbo's and they were spot on i think its ur breather i had to buy a meo valve from alan jefferys to stop mine from smoking took me a while to work it out though the meo valve goes on ur breather but it creates a draw in thesump to bring the oil from the turbo's mine was exact same everytime i was letting off the throttle the oil was not traveling back to the sump as soon as i put that valve on cleared up straight away
hope this helps
