WARNING!! CAS O-Ring Fails; Head Gasket Stop Leak Fails!!! Must Read!!
my engine had an oil leak around the CAS area but i thought it was the head gasket. I went to the parts store and bought an additive that said it would fix head gasket leaks.... bad idea. The car was losing preformance, did and 18.5 at the track, the lifters went crazy on me ticking as loud as they could scream and my oil pressure started jumping back and forth...

Uhm, according to the manufacturer's website, that product is supposed to be added to the cooling system, not the oil.

3. Shake well, Mix Head Gasket Repair in bucket or container with approximately 3 quarts of
warm water. Pour this mixture directly into the radiator.

I am interested to see where this thread goes over the next few hours. It's probably not going to be good.

No, my thermostat doesn't have a filter on it either.
The problem is that the product you added to your crankcase is advertised as consisting of a particulate solid in suspension which is water-soluble.
I think you're the first one here. Or at least the first who admitted it. 
Here's a quotation from the manufacturer's FAQ on the product pictured:
Lesson of the day- don't pour anything through the oil filler that isn't oil.

But my purpose here is just to let others see my mistake
and keep them from following my steps.

I accidentally added the Bar’s Leaks Head Gasket Repair into my engine oil, what should I do?
Bar’s Leaks Head Gasket Repair is only designed to be added to the cooling system. If the product is installed in the engine oil and the engine has not been started, in many cases you can remove the valve cover and drain the oil leaving the drain plug off. Then use an engine flush washing out the head keeping special attention to the oil return holes that run down to the oil pan. Clean these out and pour the engine flush down these holes flushing everything into the oil pan and out the drain hole. If the engine has been run, you need to take the vehicle to have a professional mechanic evaluate what can be done to clean the inside of the engine.

You put it in the cooling system! The reason it became clumpy and stuck the the filter. Was because it had a chemical reaction with the head gasket repair. I have used the head gasket repair be for it works if you put it in the cooling system and not the oil!
Let me guess you bought it and poured it in the oil with out reading the directions, mabe next time you will read directions. hope everyone learned from his mistake.

lol, it took me a while though before i realized what was going on with my car. Because of this stupid mistake i put in an order for pistons and rods, new lifters, valve springs, i'm polishing heads, and a couple of other small goodies.
I hate to add insult to injury, but if the CAS was indeed the source of the leak then an 85 cent o-ring would have solved your leak...ouch.
Once you pull the cams off, check the first journals (the ones closer to the timing belt) they are the ones that will suffer the most damage from oil starvation due to the tension of the timing belt. Hope you can save most components.
Question, is the product gritty or fine powder?

my friend used that same **** to fix head gasket leak in his 240sx few months back. car wasnt moving prior to this **** and after he added it to his COOLING SYSTEM it ran fine for about 3 months until he decided to take it apart for a rebuild.
