Chris Wilson Posted July 24, 2017 Share Posted July 24, 2017 Having found an engine in a customer car with a leaking oil pressure switch (Jap spec TT none VVTi block) I have now sorted out just what the hell is going on, so if someone finds they have a switch that appears to have a big diameter, coarse thread an that Toyota only supply a fine 1/8 BSPT thread replacement I have the means to address this, but DO NOT throw the "big thread" switch away, I need it to effect an answer! Just so folks know a fix is available.... Quote Link to comment Share on other sites More sharing options...
