I posted this on another board, but this seems like the more fitting forum for it.....

Hey, my first post over here, and from looking around, this looks like just the probe discussion area I've been looking for!

Here is the situation. 93 GT 2.5L Auto.... Well, I bought an auto car because from my hillbilly roots, I know that auto's yeild more constant et's.. a bit lower over all, but the consistancy was important. I was looking to get into the sport compact area, because I'm sick of seeig DSM cars, and Honda's getting all the attention and decided...why not a probe?

So, in my first 3 weeks of owership, I decide to begin to see where the car could go in the performance area, and began making some passes with the G-Tech for a baseline (not too many stipsare open herein the winter), and was holding the car out to about 7500 RPM between shifts, but always experimenting trying to find that just right Shift RPM the yeilded the best ET. Well, loks like those high RPM's took their toll, because now the engine has the knock from hell. So I took it into the dealership, and tey din't even boter to pull the valve cover... instead they told me I cracked a piston... This is a TAPPING noise, uneven, comng from the top of the motor, not a consistant knock. My guess is that they just didn't want to deal with it. My guess would hav been collapsed lifter, or or a lash adjust was needed. Do you guys have any creative input on that? I ask because I could just find a junkyard moto, but it would cost $1300 to have it in the car, and would prefer to use the current motor and save a few bucks if possible.

yeah you dont replace an engine before rebuilding it or building it up. unless you were swapping a ZE or something.. its just a waist.
a lot of people do engine flushes including me and it helps some ticking. it can come from a few areas. lifter tick.. or maybe TBT. timing belt tensioner..

It's your timing belt tensioner. I know it sounds like you have a rod about to go thru the block...but it just needs a new timing belt, tensioner, and tensioner arm. Replace your water pump while you in there too. I got mine thru www.fordpartsonline.com and found the service and prices are great. Let me guess, your car has about 110-120K miles.

Could also be your HLAs ticking. It's a common problem in Ford Probes.
