I got one from there, my mechanic who is also my cousin recommended them. had it in about 4 months and have not had any issues so far. i have almost 3000 miles on it.
Are you absolutely positive that it's a rod knocking?
Not TOTALLY sure, but when cold, there is very little noise (if any) and the engine is not smooth like it once was. Once it starts warming up, it becomes obviously audible. I guess it could be something else. Not sure what though as this seems to be a classic symptom. I thought of torque converter bolts, but I doubt that. Bad coil pack? It wouldn't change from cold to hot.

Suggestions?
In my experience, if it's actually a rod knock it would be present all the time, and go louder/faster with engine revs. It would also be extremely loud. You would almost feel the vibration (if is was a bad knock). Have you checked the oil pressure with a separate gauge under the hood? Perhaps it's a lash adjuster or a rocker arm. Could also be a cam phaser going out or a tensioner that isn't keep tension on the timing chain, causing it to slap.
It just seems to me that the possibility of a connecting rod knocking would be far down the list, given what it usually takes to spin a rod bearing. Is it losing coolant, but it's not obvious where the coolant is going? Do you ever hear the sound of rushing water behind the dash while accelerating? Is it hard to start after sitting a while (coolant in a cylinder). If coolant is slowly seeping into the oil it may loose enough lubricity to cause a rod bearing failure, but only if you're revving the p*ss out of it.
I started a 2 threads of two engines that knocked on two different trucks, one turned out to be a bad Knock sensor, the other worn camshaft caps and heads allowing loss of oil pressure and making the lifters lnock.
Hmmm, sounds like I should do some REAL diagnosis before I do anything else. I know that it has more than one of the famous broken exhaust manifold studs. I'll pull the engine codes from the computer first and go from there.
