Well when we first started the car, because the tapping was definitely coming from the top end, not the block, I suspected lifter tap....then when I got to thinking about it the had been sitting for about 4 days. Gravity probably drained most of the oil out of the heads.
So today I went and got 5 quarts of cheapo oil 1 quart of Automatic transmission fluid and a normal Fram oil filter and then my normal 6 quarts of Mobil 1 5w-30.
Then I filled up with 4.5 quarts of the cheap oil and the AT fluid, let it run for about 15 minutes at idle, drained and put the Mobile 1 in.
Surprisingly enough that motor is squeaky clean, because after I drained the flush fluids, they were nearly as clear as they were when they went in. Unlike the flushes that were done on my PGT
In anycase, my initial reaction was right, simply lifters tapping due to the poor initial lubrication. But thanks for the replies guys

P.S. It's HIGHLY unlikely that one of the LIM bolts made it through the intake valves and back out the exhaust valves......they're like 2 inches long! I could see a TB Plate screw making it through, but anything larger than that would be pretty hard pressed to get through the intake valves.
