In my old Explorer with the 4.0L, I'm at about 137k miles I believe. These engines are of course known to have timing chain issues.
I've heard rumblings that a pre-oiler can make a big difference in helping the chains and tensioners last longer.
Has anyone installed a pre-oiler in a vehicle or have any experience with them?
A quick Google search yields a lot of results.
I had a passing idea of installing a toggle switch for the fuel pump relay and just cranking the engine for five or ten seconds before starting it. I could do that for about ten bucks and an hour of time. It may not be the best approach for starter motor longevity though.
