The Engine oil cooler hose is leaking on the inlet and return hose. They are leaking where the metal line connects to the hose . No replacements are not available from OEM GM parts GM # 15737969 and # 15737965. I am hoping they can be replaced by hydraulic repair shop making up the special fitting onto a flexible hose. Don't know how the connection to the engine is removed just in front of oil filter is a connecting block of sorts. Anyone having experience removing those lines from the engine and how to replace those please advise as to how they were repaired.

ENGINE OIL COOLER LINES

Lease department of the dealership where I worked had a fleet of Astro vans out and when they were taken out of service , 1/2 of them needed those lines/hoses replaced .
I had to have a oil feed line for the air compressor on my Cat made up at a local truck repair shop . 800 degree and 500 Psi was the spec on the hose they used , fittings and all was within $5 of ordering the part from Cat, ready in an hour.
I hope you can find the same service and availability close to you.

Can't remember any problems removing the lines from the engine on the Astro vans , if memory serves , rad end was a tight squeeze. I'll scratch my head while looking at the diagram again.

EDIT: If possible can you post a picture of the lines at the connection to the motor , I think there is a spring clip that holds the fitting and line together , but I'm not positive.

I cannot see the connector to the engine block. it is between the oil filter and exhaust manifold looking from under i can only see the block with what looks like a swivel connector attached to the engine. the diagram in the link shows the connectors but i dont know how the lines are removed.

There is a spring clip. When I changed my engine fitting out I pushed up on the oil line pulled the clip and the hose easily came free.
