Rebuilt 2.4. New rings and rod bearings. Buitl blah blah. I primed the pump with breakin lube. Did the first start, sounded good. Took it up to 2.5k ish rpm.for a bit did fine. Changed oil. Tuner came. Tuned my idle etc, then we stated tuning for 9psi. Running msns full stamd alone.
Problem: im geting a weird knock from seems to be bottom end, hard to tell, when i creep into the 3k~4k area. Then goes away. I cam hear while driving (no boost) and while parked and i move the TB. I had a friend press clutch in and rev it, still there, so i think that eliminates the tob. Oil press has been fine, no real impact to performance that i can tell.. i havent boosted since b.c i want to find out what it is. The tuner did something woth the timing in that are to see if it was spark knock ornsomething to that effect, and playing with thebspark didnt seem to have an impact on the noise. Just change my oil after, and found no shavings. Im going to tear apart the filter and investigate further.
Any one have any ideas? Thank you.
