Back in the day (early 80's) I was a line tech for a Chev dealership. The engine guru at the shop magic fix of the day for noisy lifters was drain the engine oil and add 2 quarts of auto trans fluid to the replacement the engine oil. Didn't over fill. So 3 quarts oil. 2 quarts trans fluid. Let it run for 30 minutes or so at idle. No load on the engine. Then drain and replace the normal engine oil. Per the engine guru trans fluid is highly detergent and cleans.
It worked 9 times out 10.
