Oil filter leak. Substantial amount

Just dropped my jdm 5vzfe into me 4runner. Because it was jdm I had to move the oil cooler over to it from my motor, and relocate the oil filter from the back location (where the cooler goes) to the front one.

I started it up, and almost immediately I get a stream of oil running down the block from under the filter.
The cooler is pretty much dry.
I have ensured that the filter is tight...
The block union, fitting that the filter screws onto, is torqued down tight. And I ensure its to the 18 ft lbs torque spec.

I can't figure this out. As much as I can tell there is no other seal on the filter, aside from the one it comes with.

The only two things I can think of, are a faulty filter getting another tomorrow to check this.

Or when I installed the cooler. I didn't have the o ring for it, so I just put a "little" bit of red fipg where the o ring would go. I stress little.

I'm lost here and need some help guys. Thanks for reading my rambling

When you moved the oil cooler into new location, did you re-use the jdm oil cooler or the old oil cooler ? I think I re-used my whole oil cooler set up from my old engine with a new o-ring that goes between the block and the cooler. I know the jdm and the domestic oil cooler o-ring are different sizes, what I also remember was the bolt that holds the oil cooler were different size. Maybe used the wrong size bolt. One is longer that the other I forget which one is longer. The jdm oil cooler is in different place then the domestics so the jdm oil cooler bolt is different size then the domestic. But I'm not sure which bolt fits properly with which oil cooler in the other location. Do u know what I'm saying ?

I do get what your saying. I only have the usdm cooler and bolt and such. The jdm came with the filter and a cap. No cooler on it.
 
That cap that goes over the oil filter hole has a o-ring. And the usdm is different bolt size then the jdm for that cover and different o-ring. Did u use usdm cover to that other filter hole ?

No used the oil cooler on the back hole, where the filter originally was, and the filter on the front hole. Using usdm bolts for both.
 
No its got red fipg on it.

I'll have to change it. It just doesn't make sense that it would cause oil out of the filter.

can you get pics, or video of the leak?

maybe its leaking, and running down/back then dripping off the filter?

im unfamiliar with this set-up, so I don't know if that's even possible..
 
Yes please take pics and videos. Look there with a mirror and check the oil cooler carefully. Did you try new oil filter ? Did you change the oil pan ? Maybe bad seal around oil pan ?
 
Long shot but check the seating surface on the new mount. I cannot tell from your post if it is leaking around where the filter is attached or where it was attached. If it is where the new filter attaches then check the seating area. I had a similiar problem in the 80's with a relo kit on my MGA. The area when the o-ring of the filter hit the seating area was not machined correctly so it never seated. I was amazed how quickly I pumped 4 quarts on the driveway. I tried again and another 4 quarts. Dad told be to step aside so he could "fix" it and there went a few more quarts before we finally figured out that it wouldn't work:ybrick::deadhorse:
 
I had what i thought was a leak from my oil filter but turned out to be the oil pressure switch right above the oil filter that was cracked and dripping oil on to the filter and then everywhere else from there. Replacing required taking the filter off and the use of some swivels and extensions but was fairly easy. Info on the part:
83530-0E010 Oil Pressure Switch
 
Alright so I got a video for you, that's uploading now. But I'm pretty sure I got it.

I had dad pick up another random filter while he was over town. He ended up with a Purolator classic from advance. Before installing I checked it, the k & n that is leaking and the k & n from my old motor, against the extra filter union bolt I have. The old one and the Purolator threaded on real easy, while the bad k & n would get hung up on the first couple threads. Not sure how I had missed it, but the new Purolator filter appears to have solved the problem. Thanks for the help as I panicked a bit on this one.
 
Nice! I'm glad to see you fix the oil leak. Got me worried for a second. I am planning to drop a JDM motor into my dying Runner. I just have a few questions on if its worth doing? Even with moving the original oil cooler to the new motor and relocating the oil filter as well? I'm from CA, I don't even know how that would even affect the smog law over here...

You can PM if you want to keep this conversation separate from the thread.

Nah wherever is fine. It was quite a bit of work with the jdm, but honestly, I feel it's worth it. If you find my thread on the swap there's some pics of the valvetrain, man is it clean. The motor itself is just in great shape. I got it fired up and drove it tonight idled right at 5-600 rpm. Purred like a kitten.

And really, this was all just because of a dud filter. I don't think it had any thing to do with relocating the cooler. That took like 10 minutes after my hex sockets got here.
