Oil in throttle body and intake tube - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

NJ-JRS · 08-05-2013, 09:28 AM

Hi Guys,

Considering I have an RX catch can, what would cause oil buildup in my intake tubing and throttle body?

I swapped out throttle body's this weekend for a ported one (which I've noticed ZERO improvement with in terms of the dead spot and throttle response, but that's a whole other issue to deal with), and during the process I found somewhat-dirty oil in the oil body and intake tubing that I had to wipe down with a paper towel. I had gotten the catch can at pre-1000 miles before I even had the intake, but they're not directly in sequence with each other anyway so I'm not sure if that matters.

Is some oil buildup around there just natural, or could there be an issue that I need to insect?

Thanks!

Is it hooked up correctly?
Have you drained your catch can?
Have you done a top end cleaning to get the pre-1000 miles gunk out?

You have a 2 oil lines to the intake, dirty(from the pcv to the intake manifold) and another (clean side) that's supposed to be negative pressure from driver side valve cover to intake tube. I was wondering if a second catch can is required...?

NJ-JRS · 08-05-2013, 01:09 PM

I have drained the catch can many times, but have not done any cleanings.

Though I can say it seems the oil is coming from the pipe that is fed directly into the intake tubing to the left of the tube connector piece (RotoFab setup if that helps). Does that help narrow down if there's something in particular I need to fix?

Here's an old pic from when I installed if that helps anyway unfamiliar with how the roto fab is set up.

Actually I have used Tectron's fuel system cleaner once or twice if that's what you were referring to.

More than likely the Oil is coming from the Clean side which is the tube that runs from the rear driver side valve cover to the intake. You could place another catch can on there but there are other options. You could install a breather and cap off both ends or you could do something like the 1LE separator.

I myself will be doing the 1LE separator which should be coming in this week (was told it will ship today). That i know of i will be the first V6 on the forum to install it so I guess we will see how it works out.

Correct me if I am wrong, but you said you installed the catch can before the cold air intake right? If you did, you may have installed it wrong. In the picture you posted the line I circled should be cut and hooked to the catch can. You may want to check this out

Sledgehammer70 · 08-05-2013, 05:34 PM

This line that I colored red is where the oil is coming from. It is your breather. The fastest way to fix it is to get a oil breather cap and seal off that line.

I just did this and now no more oil in my intake.

I have had my car for a few months and I found this when taking the oil breather line off of my intake.

You can see the oil in this image:

New breather cap:

I will note... this breather cap seemed to have some sort of pressure valve on it that caused my cap to make sucking noises. I ripped the pressure valve off the bottom of the new oil cap filter and it works like a champ.

Final layout

The breather cap will help with the RX catch can, but I stand by my last post if he installed the catch can before the intake. The picture shows the intake installed and the line that should be coming from the catch can to the intake that should be cut and run to the can, it clearly is not.

I agree with that point.

Can we see an image of your catch can install?

The RX Catch Can install should look something like this.

NJ-JRS · 08-05-2013, 07:24 PM

Hi guys,

Its installed the correct way according to your pics and instructions. I'll take a pic later when I'm home to post and confirm.

But the oil seems to in fact be coming from the line sledgehammer highlighted above with the red line/arroe

NJ-JRS · 05-16-2014, 03:57 PM

Hi Guys,

Hate to resurrect this old thread but I'm still having the issue of the clean line from my picture above (the one running vertical next to the oil cap) leaking oil into the intake tubing. My catch can is installed correctly as per the RX instructions, but from a few things I've heard some people have had this problem with this line leaking oil.

Does anyone know of a solution for this?

Thanks!

intensifi · 05-16-2014, 04:03 PM

Sounds like you are referring to the clean side.

For that you need a 1LE separator or Elite makes a separator now. I wrote a 1LE separator install DIY for the LFX. Find it and have a look.
