So a mechanic buddy of mine says that if I have an oil leak it could be affecting my slave cylinder. He says the oil could get into the boot of the slave and ware out the seals. when I checked my Slave is always covered in oil. I'm guessing the oil is the reason I've been chowing through these slaves. Since then I've found an oil leak on my valve cover gaskets both sides. They were leaking pretty badly. I've gotten those fixed and will be replacing the slave one more. The transmission belly is covered in oil. I hope it was coming form the valve covers or do you think it could coming from somewhere else also?
