oil instead of coolant Sign In

I have a rusty old 1992 Ford F-150 straight 6 300 4.9l engine. It has a small leak in the intake or head gasket. It is mixing the oil and the water, but, very slowly. The truck simply is not worth fixing correctly. I know there are oil cooled high performance cars. What will happen to the truck if I drain the coolant and fill it with a thinner oil? Will this work? I only drive the truck about 3-5000 miles a year anyway. It is the second motor in the truck. This motor was free, but, it had 350,000 miles on it. Now the engine has
375,000.

It's not going to be an intake problem with a straight 6. It's a lot more likely a cracked head. Forget the oil idea. Your only option is to remove the head and fix it right. Just make sure it's not trans fluid in the coolant from the radiator.

I agree on the head HT . What are the odds of it having a eng oil cooler in the rad tank ? I've had several chevy's but cant recall a ford.

It does not have an oil cooler. If the trans fluid is leaking from the radiator into the coolant that would be an easy fix. It is not worth repairing the head if that is the problem. I think it is the head or the head gasket. I could just change the oil every 1000-1500 miles. This would only be 4-5 oil changes a year. I do not drive it that much. I was just thinking that if I replaced the coolant with oil that if the oil leaked it would be leaking into oil so it would not be as big of a deal. Would oil being pumped through the radiator not dissipate the heat as fast? Would the water pump not pump the oil? Why or why not. I know that it is not the correct way to fix the problem. I am willing to experiment a little with it. I will just drive her till the engine finally blows and buy another truck. How do I make it last the longest without the "HEAD" ache?Mad

Try a produdct called BARS LEAK and get a lower pressure rad cap say in the 6 - 8 lb range . i dont think the oil thing will work , Cant say why , it just don't feel right.

Re: oil instead of coolant Sign In

Engine oil doesn't dissipate heat, like water/coolant. Just keeps getting hotter. Can you imagine dumping four gallons (or more) of oil into your radiator? Not to mention the viscosity of oil. Don't think the water pump would much like it, either. Fix the head or dump the vehicle. Yeah, if it was trans fluid, you could just fill the cooling system with trans fluid, huh? NOT. Come to think of it, WD40 is quite 'thin'. You could buy a couple of hundred cans of WD40....
