ive got oil coming out of c4 breather when i rev car over 4000 when driving

about 3500-4000 stally
full manual valve body
after market oil cooler

im only guessing that its coming from there as it only does it on the road , ive had wheels in air and stalled it up and tried everything but am unable to get it to leak when at home

can anyone do a few measurements for me to make sure ive got the right dipstick and tube lengths , its a clevo c4 , tube in pan

got the same problem, have been told that my dipstick is prob 6 cyl version. basicly ive just driven the car till stops blowing smoke and hope for the best as no one in canberra have a spare dipstick lying around

it didnt last the qualafiing burnouts a the nats
once again i had stuff all money or time to fix problem
glad i left the blown 396 at home
