I thought my leak to the front of 4 was the valve cover gasket. Now I am leaning more towards the seal on the oil cooler. Seems to only really leak when the oil is hot.

Notice how nice and dry the other side is.
No idea why that hose clamp is in the heater pipe. Don't judge my driver side tin can heat exchanger fix. It works. And again, it isnt a drip, it's a hot engine issue only (as far as I can tell), although hot oil would drip easier the leak doesn't happen when parked hot. At least not as far as I can tell. There will be the residual dropping from stuff hanging on the metal, but once it falls that is it. Drove it around cold yesterday and no dripping. |

The fact that it is a hot engine issue speaks to the fact that with cold oil at start up, you’re bypassing or partially bypassing the oil cooler, but when hot you should have full flow through the oil cooler. |
