Hi,
I am concerned about something in my Rx-7. I noticed oil in my blow off valve someone told me that it is normal in an Rx-7 but i am not sure. Could anyone help me with that.

I cleaned it then went for a run and then came back it had oil again.

 

Id say the oil grooves in the turbos designed to cool the turbo have become mishappen due to dirty oil wearing out the metal. The oil is being captured in the air stream in the housing of the turbo and flowed along out the blow off valve.

Unfortunately there is no simple and easy fix. Clean the mess and check oil levels regularly or change turbos. Sorry for bad news.

 

A small amount of oil is normal - Check the IC hoses If there is a lot of oil then thats bad - the turbos need rebuilt - a light coating of oil is normal (ie no puddles in the hoses or bottom tank of the IC)
