I have a 6+ year old DOA in my 4Runner. No problems, no complaints. Way better than what was in there originally. Motor purred right along this last summer towing a trialer with another motor (2FE from Land Cruiser) for Tim to work over. That was from New Mexico to NC. I also had a DOA head on another truck that I sold a few years ago. Tim knows what he's doing.
