1998 C70 2.3L T3, 223k

Was making some repairs to my car on an abnormally warm January weekend. Oil was about ready to be changed (first time since the head gasket work). When I went to remove the oil filter, I noticed that I have a seeping oil leak of some sort above the filter. I'm not quite sure where it's coming from, but there is a pipe or two up there below/behind the ac compressor. I'm not sure what this is exactly.

Seems like it's related the the oil cooler lines that run to the radiator, but I'm not all that familiar with this subsystem. Any advice or observations here?

When I did the head gasket at 220k, I made a substantial number of repairs. I have a completely new heating/cooling system - from the radiator to expansion tank, to the heater core, and every hose in-between.

All upper engine gaskets are new. All heating/cooling hoses were replaced. I have a new PCV system and oil trap. All intercooler and vacuum hoses were upgraded to blue silicone from IPD, FCP, and Snaab. All upper oil seals are new. Also upgraded to an R-type exhaust manifold. I only run Mobil1 and have no problems with the Turbo.

The only wear items I didn't replace were the water pump, oil pump, and timing belt... and the oil cooler hoses.

Are these hoses are known failure point?


Older picture btw. I also have the MSD coil upgrade.
