I have quite a nasty leak that has started on the back of my 3.0L TF motor. It is down around the area that the power steering pump is mounted and I can't get in close enough to see where from when the motor is running. The leak is that bad that the oil flows out while running the motor. It isn't the rocker cover gasket. It is lower down, I'm thinking the oil pan upper seal. Is there anything else around the back of the motor located near the power steering pump between the Exhaust manifold height and the lower oil pan seal. Tried getting a mirror down their to look but still having difficulty. Any help would be greatly appreciated.

Thanks all that looked at my post. It's ok, I found the leak. Turns out the oil was running along other parts before making it's way to the back where I could see it. It is coming from the camshaft oil seal. Turns out the seal is rotating with the camshaft and sliding its way out. Can be pushed back in by hand but when you start the motor again it just rotates back out. Looking for a mechanic to help fix it cause I haven't done anything to do with timing in a car before so not feeling confident to do it myself without stuffing it. Anyway, time to get back to researching incase I have to do it myself in the end.

When it comes time to replace it, consider replacing the timing belt at the same time if it hasn't been replaced recently. Kill two birds with one stone, the timing belt has to come off anyway.

Generally that happens when the seal has been forced out of place by pressure, check the breathers are not blocked and causing the rear bank to pressurise

Timing belt was done not to long ago by the last owner. Will check the breathers and make sure to clean/replace them. Going to use this time as well to clean up the motor and try to fix a couple other small leaks. The car has 210 000 ks so by the looks of whats leaking it has had a tough life. I called around a few local mechanics (Townsville, QLD) and looks like I may get some of the RAEME boys from work to help me and pay them. Mitsubishi up here wouldn't even give me a quote for replacing/fitting the part. They asked if I had ever been to them before which I haven't cause I have only been here since the start of the year and also when I told them it was an 98 model they gave me the number for the local RACQ workshop cause they don't deal with cars that old at Mitsubishi. As for RACQ workshop, rang them and got told the mechanic was busy and he would call back, 45min later I called again and spoke to him to be told that he would have to ring for prices on the part and would call me back. Sure enough, no return call. Don't think he liked the fact I told him the timing belt doesn't need replacing since it was done not to long ago. Called a few other places and had the same deal of either not wanting to do it or passing me onto another number. No wonder I try doing as much as I can myself.

If I find that the breathers are the problem and fix them is it possible to get that camshaft seal to reseat or will it still need replacing?

Once the breathers are working properly the pressure inside the crank case should be a lot lower.
If the oil seal has been spinning, as you say, the outer edge of the seal will be worn as well as the cavity it sits in, I'd be tempted push it in and then try to get some sort of glue in there to lock it in place. Superglue in the joint between the seal and housing, perhaps?
