Hi,
I am no expert in cars, hence some it may not make any sense.
I have a honda accord DX (4 cylinder Vtech) with 143K miles on it. As usual I got my oil changed at Walmart, but the difference being that this time I got the thicker oil as we used drive the car for 100 miles a day. (Also recommended by the technician at Walmart). I drove for 12 miles and started to smell something burning so when I stopped to check the reason for the smell. It was some kind of smoke coming from beneath the engine, which I thought must be due to residue of oil. After 3 weeks I noticed some liquid dripping, which was liquid from the radiator. It had coolant and oil mixed, so I took that to the mechanic and he said probably the head gasket is gone. So I got the head gasket replaced and the cylinders pressure checked with no issues. I also got my timing belt changed since he had already opened up the engine (Now I kick myself for doing it). The technician removed the oil from the coolant and my car was ready. After 3K miles I saw the car getting hot again so this time when I checked there was no coolant in the resovoir. I added the coolant to the resovior and took it back the next day. The car now lies with technician and he is not sure what is the cause of it. I saw a similar case on the internet with a 99 accord and they ended up in replacing the engine. What could be the cause no one knows.. Also one more thing the technician mentioned that there is no water in the oil. What are my options here ?

Hi,
I forgot to add a bit of information. During the second time I saw the car getting hot and checked that the coolant was resoviour was empty, there was no coolant in the radiator or resovior.
Thanks.

Well I had a similar problem with my clk benz. My car overheated and stopped. Next day I started the engine and it worked but I discovered later that oil and water had mixed in my engine. I called a mechanic and he changed the top gasket. I used the car the next day and discovered something even more disturbing, both cooler and engine had a mixure of oil and coolant. The mechanic suggested there was probably a crack in the block engine and I may need to change the engine. Another mechanic who works with benz brought some relief, he felt the radiator or the cooling system needed to be replaced and it's not a big deal.
