    I have a 92 ford explorer v6 4x4 5 speed. I did a oil change to it a couple weeks ago and it started making a "knocking noise" so I decided to go till next oil change and open up the filter which had no metal nor did the oil have any that I could notice. It only makes its peak loudness at 900...

    Front end knock/thud when turning and accelerating?

    I have been driving my explorer for about 2 years now, but it has been in my family (My dad drove it) since 1998. Other than some small issues like replacing tires and a couple other things, I haven't had much trouble. Recently, I have been hearing a knock/thud noise from the front end when I...

    oil leak - backside of engine

    As an FYI for those chasing the various crazy to diagnose oil leak our rigs develop, I just discovered the cause of one of mine I'd like to share. When replacing the heads, with new aftermarket heads, and all the gaskets, I failed to notice that the LIM gasket fit a little skewed so that one...

    OK, it's a lifter!

    Ok, I surrender. The knock is been deduced to be a collapsed lifter. It is worse when warm - much - but not always. I am thinking of going in and replacing 1 lifter, as I simply cannot afford to do more. I assume that pulling off the rocker cover will reveal the shot lifter? :( Is this a one...
