Hi, I am new to this forum as I am trying to find answers. I searched without much success.

I have been having this problem for the last 2-3 years. Anytime it gets below 10 degrees outside, my 4.7 starts spraying oil over the passenger side of the engine. The truck doesn't use any oil until it gets extremely cold out and starts spraying. The first time this happpen, they replaced the PCV valve with a new dodge valve. Two weeks later, started all over again. They then checked for a service note from dodge and found that there was a call on this and how to fix it. So they fixed it again. Then it got warmer out and didn't happen again. Then last year it did it again. Again, 10 degrees or lower out. Once it warmed up it quit doing it.

Now we just received another cold spell here in Wisconsin along with 14" of freaking snow, and it started doing again today. +3 Degrees out on way home. This morning it was -2 out, I let the truck warmup for about 20 minutes (no garage) and went to work and it was fine. Got home tonight, the Throttle took about 2 minutes and a few quick revs to get it to idle down. When I got out of the truck, I can smell oil on the exhaust again... Why can't they get this to stop doing this. I have 112,000 on the truck and it has only been doing it the last 2 winters. What needs to be fixed to stop this from happening? I love this truck/engine and don't want it ruined.

I drive 30 miles to and from work daily, and have my dealer change my oil every 3000-3500 miles regularly. I hardly do any short drives - maybe 2 times a week where its under 4 miles per drive. I have had 2 dealers work on this and obviosly there is a problem they can't correct.

Please help!

Thanks,
John

 

Bump.

 

Hey John sorry to hear your problem but maybe try to replace the oil sending unit its only about $20 here in canada (so must be cheaper down there). I had the same problem on my 2004 HEMI not only spray thru the PVC valve but sometimes would read no oil pressure its easy to change and should be mounted on lower passenger side of your block

Good Luck

Thanks Myles,

I will have to bring that up to them. Only I don't loose oil pressure on my gauge. They just put a condensation seperator in it on Friday, will have to see if that helps.

Oil pressure sending unit has nothing to do with it. Your PCV valve is obviously plugged, therefore the next easiest place for oil and condesation to escape is the dip stick tube which would explain the oil burning off the pass. side exhaust manifold. Check your pcv valve and hoses again and take the valve cover off and check for obstructions as well.

 

As I wrote before, I have had 3 pcv valves put in the 2 years. I highly doubt they have taken the valve cover off to inspect it either. I will bring that up to them. The oil on the left side isn't just burning off the manifold, the oil is litterly sparyed all over the entire side of the engine, not just near the dipstick, but towards the back half of the engine and coated with it.

Thanks for the reply!
John

 

No help here. Sorry. The dealer probably did the TSB? Here is the link. http://dodgeram.info/tsb/2006/25-001-06.htm
I have never had that problem. Just the sludge gunk build up in the oil fill housing. I wrapped the oil fill housing with thin sticky foil plumbing tape. Works great. I'd say 95% improvement. Sorry to hard for me to post pics on this site.

 

Hey john, i have a 03 1500 4x4 with the 4.7 and mine does the same thing! you nailed it right on, cold weather i leak oil all over my manifold and it burns, i have to warm it up for about 20 mins or more if its un 15 degress. did you ever figure out what was wrong? mine started doing this about 6 months ago and it happend about 3 times in 6 months, only when its cold! when its leaking i go and pull my dipstick tube and u can hear all the puessure built up realese, im gonna try another pvc valve, but i dont know where the oil is comming from. it seems like the valve covor gasket, when it gets warmer out im gonna check it out,

 

gfizz69, yes I did figure it out. I no longer own the truck unfortunately, but I did figure out the problem before selling it.

I had to put in a PCV valve relocation kit. The stock PCV valve is located at the front of the block in the valve cover and because of it's location, cold air is causing the moisture in the valve cover and valve to freeze open allowing the oil to spew out. The relocation kit (from Dodge) moves the opening of the valve in the valve cover to the back end of the valve cover and the frozen condensation in there is no longer a problem. The cold air plus the fan on the motor are causing the condensation to freeze regardless of engine temp. It took my mechanic 3 tries to figure it out.

Hope this helps!

 

gfizz69, did this help?
