Checking for oil in intercooler

I have read lots of places about the CRD getting oil in the intercooler. Upon inspection, it appears there is not a simple place to confirm this is the case. Is there a reasonalbly safe and simple method to check for oil in the intercooler?

PS this week is our CRD anniversary, 1 year. If only I could remember how long I've been married.....

Real simple place, pull the CAC hoses off both ends of the intercooler and compare the wetness and/or coating. You won't be able to examine the build-up inside of the intercooler (short of using a sawsall). The oil will turn tar-like sticky and bake in place as with the inside of the hoses. Have you been using a Provent or an open vent mod?

I've been open venting for about a month. Should I be detecting oil traces from
the end of the hose? I'm not

You probably should see some by now. Hard for me to tell because I opted for a Provent. I have collected maybe 1/2 cup of oil sludge in the past 4K+ miles and that's running 0W40. I don't think there is as much oil coming from the crancase vent as many claim.

Still absolutely, 100% positive the typical heavy CAC oiling is coming through the turbo seals caused by a partial/temporary air filter constriction caused by the paper filter getting wet while driving at high speeds in the rain. Since I modified my airbox and installed a True-flow replacement filter, it's gone.

There are only two possible sources for oil in the intake (disallowing somebody dumping a quart down the wrong hole, of course): the CCV and the turbo bearing seals.

If you do an open vent or a Provent, that should close off the CCV as a source. If you still get oil with one of these, it means you are seeing leakage at the turbo bearings. Isn't that scary?

Now come on, DC says it "normal" for all that oil to pass the seals. Right?!?

naturist, get a load of the latest discussion on LOST. An owner in VA is reporting being denied ERG warranty because he has an aftermarket muffler. Wonder if he's working with your dealer?

My hose is 4 ft. long. Maybe it just takes awhile.
Meanwhile, are we the only ones running the trueflow?
They seem to be the best thing out there.

Most are using clear vynal hose so they can see the flow. If you are using heater hose, it will turn funky from the oil. Also keep in mind that the Provent is still working under vacuum thus will draw more oil and quicker. At that, it took a couple of months using the Provent to get noticable oil, so slow that I almost removed it as a waste of time & money.

I installed the True-flow about a month ago and I like it thus far. I put one in my Impala at the same time. How many miles to you run yours before servicing?

What size hose are you using? Looks bigger than 3/4 heater hose on the Provent. I just need to find the time to get it put in as it has been sitting on my work bench for 3 months now.

'94 YJ 4" LIFT, 2.5LTR, 5 SP, 4.10, WARN WINCH. 265X16 TIRES AND WHEELS. '06 KJ CRD limited 4wd every option except heated seats and Mirrors.

I used 3/4" ID clear vynal, braded hose (avail. at both Homer-D & Lowes). Heat the end of the hose in a pan of hot water, will stretch right over the 1" connections on the Provent. A little soap and a hook tool (looks like a screwdriver bent-up like a dental pick) will help. I went with 3/4" copper pipe fittings for the rest of the connections (had to heat the hose & stretch those too).

Also, most Provent installs on the CRD require an almost immediate 90-degree turn in the plumbing out of the Provent. Some have glued pipe and/or pipe connectors inside the Provent ports to reduce to 3/4" and also make the turns in one shot. You have to watch what you use for glue as many can't take the oil and will fail.

Well, I just got back from towing a mini-van on a tow dolly 620 miles fully loaded
with junk. I figured about 4600 lbs. I know off topic but thought some might find
it interesting.
Anyway I now have 22000 miles on my 06, after having installed the TrueFlow
at 12000. So except having cleaned the bugs and leaves off of the top, and flipping
it end for end, I haven't recharged it yet.
Sure seems to me that it allows the engine to breath well and will do so dirty.
