99 ranger 3.0 I replace the head gaskets and flushed the radiator and the fluid is still turning yellow. It was brown before the head gaskets were changed. Could it be left over oil in the coolant system? The engine runs fine. There isnt any coolant in the oil.

Its probably left over. I have heard of this thing happening. If at all posible drane it and start over again but this time dont flush it just drane it and add new radiator fluid.

I had a 1995 Ranger, but, never had to do any major work on it.
You could have some oil residue in the cooling system. May try flushing it to see if it improve.
Also, did you replace the head bolts? Or, I guess I should ask, do they need replaced when a head removed? The reason I ask. Some vehicles today, the head bolt made to stretch when it first torqued down. The manual should tell the procedure. For example it may say torque to 90 foot pounds, then torque to 120 foot pounds. Once the head bolts have stretched and had the final torque they must be replaced the next time to do it again. But, I not sure on the Ranger and gave my repair manual away with the truck.
Normally when there coolant in the oil, it a cracked block or possible head crack. So, it may be good the oil OK.
An engine usually will run OK either way, just you have white oil or brown coolant. Friend had an old '54 chevy when we were young with a cracked block and white oil. We drove that car for three years and then went into the world to work. It still up on blocks at this old man's house and he says he cranks it up now and then.
I going to say after my short spill to try a flush first and see if it help, before suspecting any thing major and check about the head bolts.

It might just be left over. I always recommend that after you put in the new coolant change it again after a couple of hundred miles to get the rest of the oil out. If you are not leaking any oil then you know that the head is not bad. So just change out the coolant again and keep an eye on it.

it could be a variety of of issues - mission is that oil does no longer stay the position it would want to. this implies in difficulty-free words one element - something interior the engine both cracked (head or block) or something gave way (a seal or gasket, incl head gasket). there is probable no straightforward restore for this. maximum mechanics will recommed eliminating the top to be certain out what is going on. this can spoil the top gasket and hence will choose replace. i understand you probably did not favor to take heed to flow gasket, yet i imagine when you're fortunate, it is going to likely be in difficulty-free words the gasket. Cracks interior the top or block is severe priced to fix and there is not any guarrantee that it received't crack back, except you replace the damaged section. the mission might want to also be as a small seal someplace interior the engine (internally) that failed. in case you motorized vehicle has a engine oil cooler that makes use of the radiator to kick back the engine oil, it could be achieveable that you've a leak there also - this must be failry straightforward to fix if the mission is interior the radiator - in basic terms replace it. in basic terms my 2cents - wish it helps.
