My 1J seems to have oil contamination. The dipstick and oil cap both have a distinct gas smell, and a recent oil change smelled like gas as well. I have checked compression which is all 180 except cylinder 5 which was about 170. I also did a block test which came back negative.
This seems to have started after my ecu capacitors failed, which caused the car to run extremely rich while I drove home. I had them replaced by driftmotion and I have been daily driving the car but the gas contaminated oil is surely not a good sign. I have done two oil changes, 3000 miles apart, and both smelled like gas.
I have also noticed that somewhere around my injectors there seems to be a strange noise, could a faulty injector cause this problem? Possibly a piston ring in cylinder 5? I also bought a rebuild kit for my afpr in case the diaphragm is causing gas to go through the vacuum line. I think a injector may have been damaged when the ecu failed, I was going to get them tested and cleaned soon, but would appreciate opinions. I should also mention i'm not running a charcoal canister, as I don't know if that would effect this.
