Ok soI had a pretty bad oil leak and I noticed it seemed to be coming out right below the exhaust mani on cylinder 4. I took the mani off thinking it was the oem catch can thing but it looked to be coming out of the exhaust runner in cyl 4. Also note that cylinder 4 has not been firing because the injector is clogged i believe. I never had this leak until after I changed the exhaust mani gasket and put a s14 t28 on but I cant see how that affects it. I just swapped the motor and havent had it full 100% running yet but it runs ok now other than the inj 4 not firing. I have also never gotten on it or driven it hard due to it not running well. I checked compression and its 160 and it held the pressure and did not leak at all. What could it be? After I drive for about ten minutes it will drip about every two seconds from under the pan after the oil has slide down the side of the block and it only leaks when running so im convinced its the clinder. Im stuck on what to do, I dont think its valves or rings coult it be because the cylinder is not firing?
