I have a 2004 Ford explorer sports track 4.0L SOHC 6 cylinder I was wondering if this is a interference or non interference engine?

This engine uses a chain to drive the cam. The chain should last the life of the engine. It is a non-interference engine.

The problem with the chain is the chain guides break causing the chain to go. The problem is when that happens the engine has to be removed to repair it since the timing chain is in the back of the engine

It's not, but does have 4 timing chains.
