2001 Toyota Camry Oil in the cooling system

Get the tests done below-could be a blown headgasket again or crack head/block

Have it block and pressure tested-do the block first to pinpoint a combustion leaking into the cooling system or a gas analyzer to sniff for hydrocarbons at the radiator fill neck.

Pressure test: do not do a pressure test if there's leakage at the headgasket this might cause coolant into the cylinders and lock it up or bend a connecting rod if cranked thereafter. The headgasket should be repaired before doing the pressure test.

If the block and pressure test passes check the following: Thermostat, Pressure test the Rad. Cap, Clogged radiator, Fan clutch, Radiator electrical fan, collaspe hoses, water pump.

Engine problem
2001 Toyota Camry 4 cyl Two Wheel Drive Automatic 80,000 miles

I had an accident on the road with a coyote that damaged, condenser, radiator. I had to drive the car for about 45 miles to get to the next town, I was paying attention to the Engines temperature and every time it was above normal operation I stopped until the engine cooled down. I also cruised down hill with the engine off to avoid more damage to the engine.

Once at home I change the Radiator and Condenser, flush the cooling system and replace the oil.

After this was done, I noticed Antifreeze in the Oil. I took it to a mechanic shop and there, they removed the engine's head and replaced the engine head gasket SET, head engine bolts, water pump, radiator cap and timing belt. The engines head was resurfaced (0.009) and pressure tested and it came OK.

After all this work was done the car ran good for about 5 days, when I noticed that the expansion tank on the cooling system was contaminated with Oil, the opposite of the first time.

I took it back to the mechanic shop and they removed the engines head again and took it to a different machining shop to verify the surfacing. The head engine was good, but they performed a valve job since and valve adjustment since the "shims" had been mixed.

The head engine was put back together with a new head gasket (only). I drove the car for about 10 days and found out again that I have Oil in the Cooling system (expansion tank and radiator).

I do not know what to do next? Please help!

Did they do the block and pressure tests or they guessing its coming from the gasket or a warped head-its still leaking finding its way back to the cooling system. The last place am thinking is the block
