Every now and then u can smell oil and it smells like its buring it but it aint i was wonder wut the fleet guard deal is on the vavle cover and if that would make it smell like oil if it was kinda like a pcv vavle or something its got 66500 miles on it also anybody no why the driver side rear door lock wouldn't work with all the others?? anybody ever had the driver side head light bulb go out and then come back on???

 

on the bulb its a short on the door locks its probably natural and the oil smell is probably oil being burned. if you look at your oil when you change it after 3000 miles it will be black with soot that is burned diesel which means you are getting the mix of oil with your diesel, that is why it is important to change your oil on a diesel every 3000 or sooner

 

it started the smell after i changed it but i just got the truck the oil was black as hell ive put 2k miles on it so fare and it aint burned none yet and it aint even black so i don't know what is up u no what the fleet guard thing is on top of the vavle cover?? I read another post on here and it said someone else had the same issue with the door lock the said the factory harness was to short and the wires where bare i guess im going to have to check it out Thanks for the help

 

Are you running Rotella? If you are try switching to Valvoline Blue or something similar. Rotella is getting a reputation for funky smells.

 

Geno's sells a bottle of mopar stuff (supposidly) to help with this issue. I think it has something to do about the blow by tube but can't confirm that.

 

yup rotella for shure huh never heard that though i thaught it was good stuff we run it in everything i think its coming from wutever is under the plastic pos on the vavle cover but i dunno its got like a filter deal and 2 hoses runnin out of prolly wut would be the blow buy or crank case breather i talked to guys at napa and they didn't no what i was talkin about i bought the truck in indiana and drove it home it never once smelled and as soon as i changed the oil like the next day it started doing it. Where can you get the Geno's stuff at is it kinda like justice brothers?? Thanks for the help

 

I had the same problem with my 12 valve. Changed the oil to rotella after I bought it and a week or so later I started to notice a nasty oilly smell every now and then. I eventually gave up looking for it because the mechanic looked at the truck and couldn't figure it out. Switched to a different oil after 3000 miles since rotella wasnt available, and the smell was gone. I didn't think anything of it until I switched back at the next change. Poured Rotella back in and the smell was back. I did some searching on a different forum and they had bunch of people with the same problem. I don't know if it is a problem with the new CJ-4 stuff or what but it was the source of my problem.

I run rotella to and i seem to smell oil too. Hummmm There ya go its the Rotella for sure then. I have no leaks and was woundering the same thing. I was thinking of going to that royal purple. in the engine gear case transfer case and rears but not sure yet I have heard all good but i have heard all good about Rotella tooo.

 

I dont think there is anything wrong with Rotella lubrication wise and I don't know of anyone with problems other than that smell. A guy I used to work with bought a 55 gallon drum of it before they switched over to the new CJ-4 stuff. He runs it in his 7.3 powerstroke and doesn't have any strange smells. Then again this could just be a wierd 5.9 cummins thing.

As far as Royal Purple goes I really don't know much about it. I run 5w-30 amsoil w/bypass in my 96 chevy 5.7 and it runs really well. Dad drove my truck now he is running it too, and mom want it in her van. If we keep talking about oil someone who sells amsoil will chime in sooner or later.
