I am chasing a weird boost leak of some sort, I have smoke tested it at a shop and I boost tested it tonight with a homemade tester with no success. I have gone through and read a lot of post on boost leak testing and I have tried multiple methods.
Current setup is a 2008 LGT sedan, jdm EJ20X longblock with USDM intake and electronics, Perrin turbo inlet, cobb sf, grimmspeed tmic, jdm twinscroll vf44 (i think is the model number) and full cattless exhaust, dechsworks fuel pump, AEM wideban 02 in the downpipe.
Issues im having with the LGT are that I am getting a boost leak when I am at WOT and feels funny other times when its still in vacuum. My tuner had me install a AEM wideban so he could get more accurate o2 readings. Whenever I am WOT the AEM wideban goes maxed out rich and lean, its random. But my front o2 is reading 11 or 12 at WOT. Also I am having excessive oil coming out of my cam seals leaking out of my timing belt cover. I changed all 4 cam seals and its still leaking, could I possible have my pcv system hooked up wrong? And if im having trouble building boost could it be causing excessive crank case pressure?
