UPDATE
Just a quick update on the problem...
Coolant found its way into the oil. I'm not exactly sure how it got in there, the head gaskets didn't show any signs of failure/leaks. All the tops of the pistons are fried and flaking. That is where most of the metal chunks are coming from. Piston skirts are marked up and worn, piston rings have all sorts of crud in them. All the bearings through out the motor are gone. Most of them show signs of heavy wear and burn marks.
Havn't been able to check out cam/crank yet (can't get crank pulley off), but the lifters looked fine. Cylinder walls looked fine to the naked eye, but I'm taking the block in to be checked out. Also, the screen on the oil pump had all sorts of gasket material plugged up in it and the bottom of the oil pan had some nice chunks of metal in it along with all sorts of fine metal shavings.

Hey guys...I have '02 Camaro SS and have a small problem....
Last October when I did a head and cam swap, I noticed sand in the lifter guides. I took them all out and there was sand and crap in them all. I cleaned them out the best I could and put all the lifters and guides back in. There was also some gunk in the cylinders, but I figured it was just from taking the heads off and the coolant going everywhere. Ever since I did the head/cam swap, there was been a nasty tick in my engine and I always thought it was a bad lifter. I really never gave any of this a second thought until now.
Today I was checking my engine oil (about 2000 miles on Royal Purple) and it was black and kind of thick. I ran about the last inch of the dipstick between my finger and thumb and the oil was all gritty and had several big grains of sand in it. After driving the car around some, I did it again and the oil is still coming off the dipstick with grit in it that feels like sand. Last time I changed my oil it came out thick and there was a lot of black sludge on the end of the oil pan drain bolt. None of it seemed like metal shavings...it was just a sludge.
Since I did the cam swap, I have put on about between 8000 to 10000 miles. I have been using Royal Purple oil and doing oil changes every 3 to 4 thousand miles after the break in.
What kind of damage, if any, can I expect from the sand in the oil like that? Where could it be coming from? What should I do about it?
Thanks
