Also check the OPS, oil pressure switch/sender, isn't leaking. There is a plug for the cam on the rear of engine that also leaks now and then, rare.
Yes turbo is really in the way and it's quicker to remove it and *Cough upgrade it* at the same time.
Oil is cheap vs. fixing leaks so think about it hard before tearing into a 20 year old pickup for a minor leak.
