- 97 Mountaineer 302 AWD
So, ever since we first got our 97 Mountaineer she's had a tick coming from the drivers side.
My first thought was exhaust leak since I have the crap manifolds. But the manifolds checked out and I couldn't find a leak at the gaskets. (early built 97 older egr style, no worries there).
Next thought was a stuck lifter. I let her idle for an hour with several revs after adding some Seafoam then changed the oil to 10w-30 Mobile1 + some Marvel Mystery Oil + some Lucas Oil Stabilizer. Even after running her for a while this seemed to make no change.
(Also note: I only use Wix or Motorcraft filters)
Now I'm thinking it MUST be a worn rocker. To test, I went heavy on the next oil change adding a bit more Lucas. Figuring this would thicken up the oil a bit and she'd get quieter if it was just a wear issue. Still no dice ... wtf ?!
So, we've lived with the noise for a while now figuring I'd replace the rockers and lifters when I had the time.
Now ... She comes due for another oil change this morning ...
She gets 5Q of Mobile1, a half quart of MMO, and a half quart of Lucas (I live in the desert so no worry on thickness). I start her up after and the noise is not only STILL there but it seems louder (though maybe I was just hearing things with irrational anger). I take her for a spin and stand on the pedal (pissed off). I do this a few times and on the 3rd run ... Silence ... It was a stuck lifter the whole time. She just needed to redline a few times to free up.
So, if you're like me and have been slowly driven nuts by ticking but also typically drive around like an old lady you may want to add some MMO and stand on the pedal a few times to see if you just have a stuck lifter that wont give at low rpms/loads even with solvents in the oil.
