| 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. | |

Replying to: deputy235 (Sep 15, 2008 11:31 am) 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

Replying to: deputy235 (Sep 15, 2008 11:31 am) 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".

Replying to: deputy235 (Sep 21, 2008 4:48 pm) 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. |
