LA 360 blue smoke after warm up

Well I thought I found me a donor vehicle for the engine swap. It is a 1990 W series pickup... Has the roller cam, but still an LA.

The engine does not smoke at start up, but as it warms up, she starts smokin blu. Would that be rings? BTW, it only has 100,000 miles on it

I was hoping it would be valve seals, but I don't think the symptoms are correct for that diagnosis. Any thoughts?

Sorry but I do find this funny. Hope you solve your problem without too much expense but a tear down sounds like a good idea here.
