Today I started the process of replacing my boots and installing the Riffraff Diesel plenum inserts.

As I disassembled everything, I noticed that there was contamination (?dust?) in what is the part of the turbo that connects to the manifold (I think you guys call it the spider). Please look at the picture and let me know if the contamination is indicative of a problem.

Thank you.

 

Looks like oil from the ccv to me. What intake are you running? Stock with a K&N drop in is notorious for letting dust by. Have a look at your compressor wheel.

 

That looks like CCV oil, but maybe a lot of it. It could just be sticking around instead of being blown through like normal if there is dirt in the air.

Mike, he has a factor box, but has missing clips, which would account for the dirt in the pipes.

 

I currently have a stock air box but am missing a clip (soon to be remedied).

I have not yet installed the CCV mod kit I purchased. I've been back and forth on whether I want to install it.

 

I've inspected my original turbo, the IC tubes, the inside of my intercooler, and my intake plenums (when I pulled them to install billet plenums). All my breathing hardware looks great, and I have never had to add oil between changes. I am confused as to why people modify the CCV... I am unsure what the goal is. I found nothing wrong with the way the system works, but my truck breathes deep and clean (Ford AIS).

With my experience, I would just get a better intake and sell the CCV mod.

 

The ccv in stock configuration:

Acts like a sand blaster on the compressor wheel.
Creates negative crank case pressure... thus masks potential blowby indications.
Leaves the cac tubes, compressor, spider all nasty with sludgey crud...

International designed the motor to have an open ccv....

 

Like Rich, Ive seen inside my system also, and with the exception of the normal film of oil, its clean. I'd also say you have a filtration problem.
Jim.

 

I agree with Tugly. I've said it before and and ill say it again, I think the CCV mod is pointless. I've seen inter coolers with 300000 miles drained and the oil removed is measured in drops. Not that I don't advocate a nice flush everyone in a while.

Dave, I stopped by your house and left the air box clip. That should help seal the filter until your AIS shows up. I should have looked at your filter now that I think about it.

Also, your turbo does have an oring for the spider it's just stuck to the turbo. I'd suggest you leave it there. It's a pain to position when it's not held in.

 

Double post points!

 

Thanks.

Anything else I should do while I've got all that apart?

 

Repair/replace the passenger side fuel line. Failure Prevention Thread

 

That's not a bad idea. Inspect your fuel line; if it's still good just preform some preventative measures. No replacement necessary. .

 

[QUOTE=A/Ox4;13265083]I agree with Tugly. I've said it before and and ill say it again, I think the CCV mod is pointless.

i too think it is...silly. the offset is negligible at best. if your building a race car-sure. of your towing race cars no.

 

I'll share, and let others judge for themselves: I have an inspection camera that I used to look inside my intercooler. I see condensation in there (it's a cooler for crying out loud) and hues of oil mist, but no "sludgy crud" in my case.



I upgraded my turbo and I saw what looks to be soot from the old exhaust leak more than anything else.

 

Rich, what kind of inspection camera do you have? I have a cheapo flea-bay reminiscent one.
