DId they replace just the cooler lines or did they replace the ones going from the block to the oil filter also..Did they replace the part where the oil filter screws on to also?I am really sorry to hear that this happened again...Do the parts have a warranty or does the garage you took it to?They should repair it again for you free of charge because that is ridiculous..I would talk to them about it and see if they will work out something with you....

Check to see if oil cooler is plugged. Remove the radiator(oil cooler is part of radiator) and take it to a radiator shop for flushing.

How high is your oil pressure? You said the pressure was high, mine runs about 40 PSI, but it's on an engine with 200,000+ miles. The oil lines should be good to at least 175 PSI. In the Jimmy's I've seen it's the crimpted ends that seem to leak, not the hoses. But as has been pointed out there are two sets of hoses, one from the engine to the remote oil filter and another from the oil filter to the oil cooler in the radiator.
See ya
