My 97 Neon has white oily substance in radiator

I have oil in radiator I've cleaned out but it keeps coming back, there is no discoloration or bubbles on engine oil stick. The radiator cap is a creamy white colour. Can anyone tell me where the oil is coming from?

SOURCE: 97 neon oil leak

Solution: Maybe.

Rear main seal is probably the problem.

My 1997 Dodge Neon has this same problem. My father-in-law (who used to be a mechanic) checked the car for me and found the rear main seal needs replacing.

SOURCE: 2003 Neon SXT Tranny Oil In Radiator

I'm not possitive but there is usually a vent tube on top of the transmission, may be possible that dirt or something is clogging it up. That would cause the tranny to build up pressure. But to blow the seal on a new radiator, I wouldn't imagine that. My opinion would be that the new radiator wasn't put together correctly. But just in case the vent tube did cause it to let go, check the vent. I hope that you find the problem. Best wishes.

SOURCE: i have 2005 neon sxt keep having code po457 evap

fuel cap is just one of the causes. Here are 2 others:

  • possible vacuum leak
  • NVLD switch is stuck or malfunctioning
NVLD switch communicates with your car's computer. A bad switch will throw a P0457 error code. Check for a vacuum leak 1st but if none is found, the NVLD switch should be changed.
Below is a link that explains more thoroughly what the module does; I do wish you the best of luck with your Neon and hope you found this information helpful. Take care!

SOURCE: 2004 Dodg Ram 1500 5.7 L Hemi

I have a 2005 Dodge Ram 1500 5.7ltr Hemi....I had a significant issue with loss of oil...the bottom of this engine and vehicle is as dry as they come. No smoke from the tail pipe...however the inside is dark...not that light grey clean burning look...I'm also seeing oil residue inside the air breather....I searched all over that engine to find what knew a PCV should look like...I finally broke down, drove to the local Dodge service dept. and asked one of their mechanics to come show me...facing the engine...on the passenger side of the engine, behind the throttle body cover is what looks like a plug with a raised center clip you grab and twist clockwise to unlock and counter to took a bit of prying with a small flathead screwdrive, but it popped up. The check valve in it was sluggish (due to the oil) and probably not functioning to full capacity. The dealership charges about $42 per but cut me a "deal" and charged me $34. You do have to remove the throttle body cover to see it and ultimately remove it....2 screws and you're there.

are you sure it was smoke and not steam? without seeing this substance myself, I am thinking it could POSSIBLY be oil in your cooling system. Didnt the mechanic tell you? It would mean a serious problem. This "waxy" substance is what happens when oil mixes with water. It might mean your car overheated and cracked the block. I hope this isnt true. Ihave seen this before. Take off the radiator cap. Roll up a piece of white paper and slip it down into the radiator. When you bring it out, it should not have anything but water/antifreeze on it. If there is any black substance, thats oil.It got into the cooling system. Now check the oil dipstick. If it looks greyish, it means water/antifreeze got into the oil system. I'm not an expert and this is just my personal opinion. Check your radiator fluid.first. Dont drive the car if you find "oil in the water." It will cause further damage and if you plan on having the car fixed, dont take that chance.

Radiator and water container

If you have a auto it may be transmission oil from the oil cooler in the radiator. Having changed the radiator may have removed the original fault but there would be still ,oil in the coolant system that is still coming out. Have the system professionally flushed by a reputable radiator shop and then have the cooler tested in the radiator.

that sounds as if your engine breather system requires cleaning, the substance is emulsified oil, normally caused by poor oil, lack of oil changes, or possibly head gasket problems, clean out all the breather hoses, filter etc, run engine until warm, drain engine oil and refill with a good quality oil, renew oil filter and then run and check again after a few miles

Sounds like a head gasket, the oily substance is actually oil. Do not drive the vehicle, at some point a $1000 repair will into $3000 repair when the engine seizes.

Oily coolant

yes, it is a definite sign of blown head gasket.
I did have only once a problem similar where the engine block was cracked but other than that,bet on the head gasket.
Take a coolant system pressure measurement, (if your head gasket is blown, the pressure in your coolant system would go down slowly)
