Where is the most likely place for engine oil to be leaking under filter on TL140?

I just developed a oil leak coming from my Isuzu engine. I lifted cab up and got a mirror and tried to look and it is coming from under oil filter. I gotta get under it and see if I can locate it. Anybody got a guess where it may be coming from? lol!

If we are going to guess, I say its an oil pan gasket. Could be the filter seal itself. What is the prize for the winner?

Are you sure it's not running down the back side of the filter? Put a new filter on it first and try it-sometimes they just start leaking around the seal on the filter. I just had to do this on a New Holland 185B a little while back. It wasn't a bit loose,it just started leaking.

Also-if you have a drain hose for the oil pan check and be sure it's not leaking at the fitting going in the pan. It may be a boss O ring style and it's leaking.

Thanks i know this was a stupid question. I just thought someone here may have had the same leak on the same SS. The leak is coming somewhere right under the oil filter/oil cooler housing. It may be the oil pressure switch. I will pull the skid pan under the machine and maybe i can see it then.

Here's the location. But i cant get to it easy.

I’d check around the filter mount it looks like some one was messing with the bolts .looks like it may be broken by bottom bolt?

O-ring to block (272) plus square cut seal under cooler (63).

Wow! That would be a bear to get to. Would you have to do it from underneth?

It doesn't really look that bad to access to me. Get some degreaser and a pressure washer if you have it and clean it up and take the filter housing off and replace the o rings and put it back on-it might be a quick fix.

heymccall may be the winner. I pulled the oil filter body and the oring was still all there but it is flat and brittle. I am gonna order the 2 oil rings tommorow and hope and pray it fixes it.
