Oil in throttle body


check for the breather pipe from rocker cover to throttle body. either you do have a problem with the rocker cover release valve on breather and allows oil going into throttle as every time accelerated **** oil. if there is not any valve there in then see whether you can fit any type of a straight pipe filter on the hose to cut out the oil flow.
