Topic: Oil leak?

[Helios]

Found a few spots where it seems I have oil leaking. There have been three spots where it seems oil has come out of the intercooler charge tubes. The first one I found was last week and I just cleaned it up. The second two I found this morning and took pictures. Dunno where this oil is coming from and when I get home I'll take the charge tubes off to see if they getting coated on the inside. Thoughts on what's causing this?

This is on the intercooler of your supercharged Sky?  There isn't any oil feed into the SC....  Look at the relief valve on the valve cover, cannot remember the name at the moment.  PVC that's it.  It should be the larger hose going into the charge tube between the cooler and the manifold.

Yes, mostly at the intercooler. Ok, I'll take a look at the larger hose.

I don't know Joey!  That residue aft on the intake elbow doesn't seem to be in the line of flight of any oil lines.
Could it be brake fluid being sprayed at the flange from the brake manifold?  Is there any evidence of a leak there?

Dunno. Haven't had time to take a look at it yet. She's parked in the garage waiting for me to take her apart this weekend. The oil has been in three different locations around the charge tubes, one of which was on the passenger side. So, I doubt it's getting sprayed around like that. I have a nasty feeling that the inside of my charge tubes will have oil in them. In that case, I wonder what damage is being caused? I suppose I would have to take out the tubes and intercooler and clean them out. I'm NOT looking forward to this weekend...
I'm also wondering if an oil catch can could have prevented some of this...?

As I recall those who installed an oil catch can had no problems with oil in the charge tubes but maybe someone who has will see this post and respond.  In any event as you say it would be smart to clean out the charge tubes.

He has a 2.4L. I would talk with Dave about this problem.

[Critterman]

I have not heard of a need for a catch can on a 2.4, I would check with Dave after you find out if you have oil in your tubes.

[Arabas]

critter, since it is a supercharged 2.4, it has the same need for an OCC as any other turbocharger engine.
of course, as you guys say, consulting with Dave is the best way to go

Not so sure I have not seen any oil and I'm going on 45k since we first put boost to it. Dave your opinion?

[Helios]

Well, I took everything apart Saturday and I did indeed have oil in the tubes and in the intercooler (I'm guessing probably about 2 cups worth throughout the system). The oil is coming from the large hose (the one from the valve cover to the aft side of the air filter charge tube. Took about three cans of brake cleaner to get everything cleaned out and half a roll of disposable shop towels. Also, had to spray out the MAF sensor with MAF cleaner. I did not spray out the S/C itself in fear of ruining the grease/ lubricant inside.
I will be ordering a catch can on Monday to avoid this from happening again. I would suggest others do the same unless you like to spend 6+ hours taking things apart and flushing and wiping. Upon my discovery of said fault, I did contact Dave and he consulted me on the best way of cleaning up all of the oil.

[Arabas]

Did Dave confirme to you that it could have been avoided by using an OCC?

He did not specifically say it in those words, but yes he did. In a nutshell, just like the website says, Dave stated the OCC is recommended for all boosted engines.

If the SC is the Eaton M60 there rotors used to be coated with Teflon and brake cleaner basically distroys the Teflon and can distroy the grease bearings for the rotor packs.  Though if you want to strip your rotors for any reason disassemble and let the brake cleaner do it's magic then reassemble.

The problem has resurfaced and I will have to take apart the tubes and intercooler again to clean them out. Still not sure what could be causing it. I know last time I was at DDM Dave, Critter, and I had talked about a small hole in the intake manifold and whether or not it could be plugged without damaging the engine.

[Sly Bob]

What do you mean by a small hole in the intake manifold?

[elff]

Yea, im curious about that as well.
Did you replace the PCV valve?

[Helios]

There is a hole in our engines that Critter, Dave, and I discussed when we were at DDM last time. Oil is supposed to come out of it to lubricate something I think. I'll have to see if Critter remembers or if Dave will chime in.
No. I haven't replaced the PCV valve as I don't know what it looks like or what to take apart to change it out.

[elff]

On a stock engine, it should be on the valve cover.  Take a look at the pics in this thread

Although, i'm not a fan of the breather approach this guy used.  I prefer a catch can.

Yeah that's the hole we talked about when the intake manifold is off. So, we can block that hole. Good. Here's what I don't understand. I have the hose that goes from the valve cover to the DDM OCC. Then, the other hose from the OCC goes to a nipple on the intake tube just aft of the air filter. Will I need to install that hose from the OCC to the intake manifold instead? and add the PCV valve? Will I also have to drill and tap an additional hole in the OCC to install the other PCV valve and a breather filter?

[Critterman]

The hole he is talking about is our engines approach to a PVC, except there isn't anything to stop oil from being pushed through it when under pressure from the SC.  There is no actual valve.  Dave was going to look into doing something with it.

Critter
Is is pCv
not pVc
Postive Crankcase Ventilation.


Yea, thats the difference between the LNF and 2.4.

[Critterman]

Whatever

Thats odd on the side of the PT Cruiser head there is a small releif tubing that had a hose that went to the stock air box just below the Filter . The Air box use to get oil in it . Dealer said it was negitive pressure of the turbo  pull that sucked it out and gathered in the filter box. When I changed the stock air box I installed a small breather on the tube and never another problem with oil leaking out. Now it pulls air in , shop said it was a poor design.

 In the Kappa W/ the S/C pressure blowing out the oil when it spools up. If it had a nipple that that a tube could be connected to and a tee into another line may solve the problem. Just  my     Rather then put it into a catch can then have to emptied .
