I have a 91 supra 7mgte, I have been doing most the work myself. I got a jdm 7mgte engine cahnged some gaskets and 4 months later I have a problem with an oil leak! it's coming from the front passenger side below header there are so many wires i cant see where exactly its coming from anyone have a pic of a engine pulled that would show hoses, and from front of turbo to the front of the engine below headers? I have not had a good oil pressure as long as I have had the car the gauge will work on RPMs higher than 2800 but will be at zero at idle or when driving at lower than 2800 rpms.
