Hello everyone, I'm new to the rx7 scene. Worked on cars and bikes before but never a rotary. I decided to get one after a buddy of mine (who has an FD, been trying to convince me to get a rx7 for 8 yrs) took me to a drift event. A month later I bought an 87 NA. Non running. I already pulled the motor. I noticed when I drained the oil it came out like a chocolate shake. Any clues of what it could be??
