Head gasket problem?

[throwedgsx]

Okay here is my problem. I blew a head gasket about a month ago. Or so i thought. I had a slimy, yellowish, lotion like substance in my cooling system. I've never seen anything like it before. I pulled my head off and replaced the gasket. The head was resurfaced and i sanded the block and got it perfectly smooth. I cleaned out my radiator, upper and lower radiator hoses, the head and as much as i could suck out of the block with a shop vac. I threw it all back together and torqued the head to 100ft/lbs in sequence using a 3 step process. I flushed the cooling system once with distilled water with heat on high. I let the temp get up to normal operating temp for about 5 mins and shut it off. I drained the radiator and took the valve cover off and retorqued my arps in sequence to 105ft/lbs. Everything was fine and dandy. Just the other day i looked at my coolant and there's oil in it again. I haven't had any overheating issues and i'm losing a small amount of oil, but my car also leaks a little oil. So it's hard to tell if that oil(slimy lotion like substance) was left in the cooling system when i replaced the gasket or if my oil is indeed going into my coolant. My oil is clean. The car smokes a little bit when its cold, but i run e85 and a byproduct of burning ethanol is water.

So here's my point. What do you guys suggest i do? Where do you think this oil is coming from? Has anyone ever had a Cometic HG just fail on them for no reason and not seal?
Any suggestions are much appreciated and thanks in advance!!

Maybe a cracked water jacket?

If you had oil contamination in your cooling system, you need to do a proper flush as even when well drained, there will be residual oil in the cooling passages of the block, heater core, radiator and all the rubber lines

The head was resurfaced and i sanded the block and got it perfectly smooth.

You sanded the block? With what? Generally any machinist will tell you that sanding the block or head by yourself without using a proper resurfacing machine is a HUGE no no. Doing so will cause your block to have uneven spots on the block which could cause a bad seal between your head and block. Generally you would see the symptoms of a blown head gasket but you do not so most likely it is leftover oil and you should do a complete flush. Just remember next time sanding it down by yourself is a big no no.
