My blazer has been leaking oil for a few years but the prior owner (my sister) didn’t do anything about it. It tooks to be leaking from deeper inside because its all over the pan. It only leaks a little per day, but if you park it for like 3 days in the same place it will have a 6 inch wide puddle. Perhaps would some of that leak sealer that you put in when you fill the oil work or atleast better the leak?

 

Don't use the stop-leak products. Chances are it can be fixed properly.

Many of, if not all came within a remote oil-filter and extra oil cooler.

This means there is plenty of hardware external to the engine that could be leaking.

The most likely culprit are the hoses between the adapter at the block to the remote oil filter assembly.

The next likely culprit are the gaskets and o-ring at the adapter.
