oil pressure & oil leak damn 7m!

aamt07 · 10-22-2010, 04:37 AM

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.

aint alot on the side of the block, oil send/return to the turbo, oil filter, dipstick tube and oil pressure sensor. its probbably the tuurbo oil drian thats leaking.

Is that above the oil dipstick insert?

You should check the o-ring on the cam position sensor. Oil can leak out of there and drip down to the exhaust manifold or get blown back by the fan. It could also be valve cover gaskets or cam seals. Those are common problems. After checking those, I would look at the oil pressure sender and the turbo oil line seals.

As far as your oil pressure, once warmed up, you should be at 4-7 psi at idle and 35+ at about 3000 RPM.

Okay 2 questions in 1, if i was to take off the cam position sensor (1.witch is infront of the engine behind the powersteering res) 2.not knowing what im doing could i mess up the engine as far as not putting it back in right? i can see now that i do have a leak from there but im sure i have more than just that one leak.
