1999 Dakota 4.7 by deputy235

I recently acquired a 1999 dodge Dakota from my sister that is rough on vehicles. She said it ran hot, so she replaced the radiator. When I went to pick it up it starts fine but there is a knocking noise in the engine. I checked and there is water in the oil. How do I check to see if she messed up a head or a gasket? Also since the oil is floating on top of the water could this be why it knocks? If I change the oil do you think the knocking will go away? I plan to fix it up for my step son, and don't have a lot of money. Any answers would be greatly appreciated.

Water in the oil may not necessarily mean its coolant. If this vehicle has been owned by someone that is "rough" on vehicles, it is possible that this engine has not received very good maintenace. In frequent oil changes in combination with short trip driving can build up moisture. This usually shows up as a whitish or light brown frothy element in the oil visible on the oil cap or dipstick. If this engine has a lot of miles and the engine ventilation system is not working correctly, moisture can build up very quickly.
 
The detection of coolant in the oil or a bad head gasjket can be diagnosed. I would recommend you perform these tests or have your local repair establishment perform them for you first. Mopars aren't noted for having head gasket problems and I haven't seen or even heard of one in years. A bad intake manifold gasket can cause a problem, however.
 
In the meantime I would change out the oil and see if the knock goes away. If it does it indicates that there was probably too much moisture (water) in the oil. Then perform the test for coolant and proceed accordingly.
 
Good luck,
Dusty

I know for a fact that In 1999, the ONLY vehicle available with the 4.7L was the Jeep Grand Cherokee. The 4.7L engine was first available in the Dakota in the ModelYear 2000 .... but you suggest you have a 1999 Dakota with the 4.7L Somthing does not jiive here.
 
HINT: Check if your Dakota has rack-n-pinion steering (1st available in MY2000)
 
To more specifically answer your question "How do I check to see if she messed up a head or a gasket?"
 The common way is to do a "bleeddown test" and a "compression test".

I beleive there is a "special tool" which is intended for this task. Some autoparts stores (Autozone?) will "loan out" special tools.

The production date is 8/99 and under the hood tag is 4.7. It must be a later production date

I didn't have a chance to change the oil yet but i got a clearer story, The truck was running hot so her mechanic put a new radiator in it. Right after she got it back someone hit her in the front and damaged the radiator so they put in another new one. After he installed the second one he noticed a slight knock in the engine and it hasn't been driven since. I opened the radiator cap and it still has water in it. If it was using this much water i would think it would be empty. I also pulled the dipstick out again after sitting for over a week and there is no separation of water and oil, it all looks the same. When i change the oil i will let you know what happens. Thanks for you help

Given the info you show above about your underhood sticker... I beleive you have one of the early MY (Model Year) 2000 Dakota. (I orderd my 2000 from the factory and took delivery in October 1999)
 
I assume you DID verify that you have rack-n-pinion steering.
 
Now that we have that setteled.... how did you determine that you have water in the oil?
 
Just incase you were not aware...
The very early 4.7L engines had a tendancy to build up water-oil emulsion in the oil-filler tube. There were several 'recalls' pertainig to this. (I am very aware of them because I initiated at least one of the recalls)
 
The 2 changes were
1) The oil-filler cap was redesigned to contain an insulating barrier from colder under-hood air.
2) An insert (factroy calls it a "baffle") was developed which slides into the oil-filler tube.
 
Both of the above changes to the very early MY 2000 4.7L oil-filler tube were intended to reduce the buildup of condensation inside the oil-filler tube.
