jack46 Posted March 9, 2009 Share Posted March 9, 2009 I pulled the opti and found the vacuum line had melted shut...so I had no vent on the opti and had a couple drops of water inside... What is odd the water looked like methanol (blue and I blend washer fluid and meth) could the corrosion turned the water blue? The meth couldn't have sprayed in because the vacuum point was closed off and the point of vacuum was other side of meth injection on the intake tube and has a one way value that closes when I blow on it. I am puzzled the fluid also was not flammable and didnt smell like methanol but the metal coverwas rusted and I have never seen that before on any opti even without a vent...

80LS1T Posted March 9, 2009 Share Posted March 9, 2009 When my opti went bad last summer there was corrosion inside the connector and that was all bluish/greenish. It was probably just water mixed with the corrosion. Quote Link to comment Share on other sites More sharing options...

It was probably just water mixed with the corrosion. Thats my hope just methanol has been a problem. The stock Throttle body isn't sealed and meth kills the tps under boost so I am paranoid now. I just can't think of a path for the meth to get into the opti I want to vent the opti from intake with a one way valve but this has me concerned. BUT before TB I don't think there is enough vacuum to perform any real venting. The first stage meth comes on >3 psi (second >5) so valve should be shut off long before meth flows.
