I have two locations on my vacuum system that have oil.. Is this a problem? The top of the intake is Jerry rigged because I broke the plugs, but I will fix them soon.

however, there is oil re residue on the big hose up top, and there's also oil over at this vacuum canister. See pics of oil in the clear hose..

should I be concerned?

 

Nothing?? I just want to be sure that having oil in the vacuum system is normal and or ok...

Happy Thanksgiving!!

 

I would start by checking the oil separator in the rocker cover. If it's clogged you may be getting oil vapour into the vacuum system where it is condensing.
Either clean the separator (or get a new one) and reinstall, or omit it completely and install the PCV modification. (Search this forum for details.)

 

cobbcj7,

Unfortunately, you have a 2004 Disco which means the oil separator valve is a little harder to access (same situation for 2003 Disco which is what I have).

On the 1999 to 2002 Discos, you can simply remove the rubber hose.... then pull out the oil separator plastic piece which sits inside the small round metal tube. The small round metal tube sits on the aft of the driver-side valve cover.




The 2003-2004 Discos have a similar set-up. However, this metal tube has a capped top which prevents you from easily pulling it out. You will have to actually take the valve cover off. Then go and pulling out the oil separator piece from under (or inside) the valve cover.




Or if you are bold enough, you can try forcefully removing this cap:

Best4x4 has offered a great alternative once you remove the oil separator piece. Don't use it. Use a FRAM FV308 and install it at the other end of the rubber hose. The other end of the rubber hose goes into the intake assembly. You simply connect the FV308 to the hose and screw the FV308 valve into the intake assembly (see circled below).

 

It's possible to drill out the top of the oil separator tube in order to remove the baffle on an '03 or '04 truck. I did it on mine but it was with the cover off while I was doing the head gaskets. You could try drilling with the cover in situ but you'd have to work out some way to stop any metal shards from dropping down inside. If your baffle is totally clogged, that might be enough.

 

If
you have an 03/04 Carb Cleaner pull the rubber hose a squirt a bunch in there, wait a bit and do it again. It might take a number of applications to get it clear but it will.
