I have a 2002 vette, I recently did the ls3 swap. With my current routing I am sucking so much oil it is fouling out my O2's, soak plugs and covering the back of my car. There is so much oil it is finding its way to my MAF as well.

I do not have the valley pan with the port coming out of the front.

The drivers side valve cover has a port in the rear. The passenger side valve cover has a port in the front. I bought a MM catch can, but he was not able to help me out with the routing. We must have 40 emails and I sent him many pictures along the way of my routing as we kept changing it per his direction. Still no good.

I need to fix this very soon, we are supposed to go to the tail of the dragon this Thursday.

The car is constantly bucking and I'm getting codes for misfire and MAF. I cleaned the MAF and removed the catch can. I currently have the drivers side connected to the port behind the TB a with the PCV and the passenger side routed to the rubber connector between the air bridge and the TB. Still have oil in that rubber connector and a pool of oil in my intake.

My dampened seal is leaking, I think I am some how pressurising the block? This is my second seal now.

Please help, thanks!

Added info:

Oil is definitely coming from the hose from the passenger side valve cover to the boot that connects the TB and the bridge. I let it hang down for a little bit and oil was draining from it. Any ideas?

 

I think if you watch this entire YouTube video it might at least get you pointed in the right direction.

 

So, according to him, he stated that the line from the passenger side was dirty air and flowed out (then later said he was wrong), that is what I have. That same line on my car seems to be pushing oil out and into the TB and intake. For clarity, my MAF is down by the air filter, not up by the TB.

He did say that in that condition, I should connect both hoses and the go to the catch can, then finally to the intake. He only has two ports, one in and one out. Pretty simple.

I can do that, but my Mighty Mouse can has three ports. What hose goes where? The guy from MM had me buy the new style cap as well. So now I have the "old style" cap that it came with and vents to atmosphere, and the "new style" cap that has a port on it for a hose to go to someplace.

Thanks for trying to help, keep it coming.

 

It could be someone removed the oil baffling in the valvecovers, perhaps to gain clearance for running roller rocker arms? Obviously, something is screwed up here. Must be a big disappointment when you call MM, then they can't tell you how to install it!! That's not too cool in my way of thinking. You would be better off with the valley PCV setup, IMHO. Best of luck to you......

 

Yeah, $400.00 + with MM, funny that my '17 Silverado 6.2 has a Elite Engineering with just about 100k miles and never a hiccup. So much for the hype.

I thought about swapping the valley pan as well, but I would need someone to explain to me why it would solve my issue before I would swap it out.

The car really wants to run, but just not given a good chance to.

 

pm me your email address used for our correspondence so we can resolve your concern of our product or begin processing a return for refund

 

Your last email to me from almost 3 months ago of the 24 in the string since the purchase:
"Well, the car seems happy. Catch can is not filling up, very little to no fumes or smoke out the back. Went for a ride tonight to check everything out. Now, I just need to finish blowing out the residue that's left in the pipes. Thank you for your patience, or did pay off in the end."
How can I help you further if I do not know about a problem?

The spec / correct routing did not change, does not change. Sometimes we adjust the routing to suit a particular side effect once the standard approach has been implemented.
Driver valve cover to can inlet
Can exit (came with a red cap) to intake manifold
Passenger valve cover to air between the maf sensor and the throttle blade (if old style throttle this is on top of the throttle, new style throttle you changed to puts this in the maf pipe).
There are two diagrams in the instructions, one for one way, one for the other. Here they are: https://docs.google.com/document/d/1...it?usp=sharing
The recirculating breather top is spec for road course application, this discharge hose can go to the air cleaner assembly, or simply exit the immediate engine bay area.

Once the install is complete, building excess vacuum in the crankcase, or getting oil to the front of the throttle body, or both, is an issue relative to the install being done different than spec, or an outside issue (such as a clogged valve cover, or air filter, or the retune not done, or bad maf sensor, or a general mechanical issue with the engine).

For sure in the emails we found at one point you had the passenger cover capped off, which is incorrect, and later we found you had the recirculating breather hooked to the driver cover, which is incorrect.

Did you ever drill out the driver valve cover pcv orifice?
-this will allow the can to handle more load, taking load off of the passenger valve cover, fouling to the air intake
-because our catch can is self regulating, keeping the can in-line of the factory pcv control point is not required

 

Amazing how clear your directions seem now. If you would have had made them that clear to begin with it would have been much different. How about labeling the cans with inlet, outlet and so on. You may know which ones are which, but not everyone else. I followed everyone of your instructions to a T. I even sent you pictures of my motor with green tape labelling each hose where it originated and ended, still you said try this, try that. Even had me buy a new style cap from you at full price, if it would have worked it would have been with the money. I detailed everything on how it turned out. It did appear for a very short time that it was working out, that was at idle, again for a short time. At one point you had given such bad direction it was sucking air when I lifted the dip stick, or opened the oil fill cap. I finally gave up on you, your directions and product and removed it from the car. I bought an Elite Engineering unit and it's been flawless.

By the way, you told me to cap off the rear vent on the passenger side. And yes, I drilled my extra one just as you asked, I still have it in an extra set of covers on the shelf of my bench.

I believe I still have all of our emails and receipts just in case this day came. I tried to find others who had one of these to see how they have it hooked up. Don't cry Wolf now, you should've taken this route a long time ago.

If you still want to discuss this civilized off line let me know. Other than that don't come here and try to make me the bad guy, I have been patient and let this go.

 

This is all the same information in the emails, and in the instructions before the emails.
The exit fitting is indicated out of the box with a red cap on it, and the packing list also indicates its port position on the can (#2, second of the two ports, from left to right on the can body).
The higher flowing cap than on the original order, was an attempt to resolve, what in my impression of the side effects, was abnormally high crankcase flow for your power level (it happens sometimes).
The sucking air was due to the incorrect install. at no point do the instructions ever direct to cap off the passenger cover (front) or otherwise stop the clean air supply to the crankcase.

My response here is only due to being called out on here. You had my email all along and nothing since July when you were happy with things.

You have a lifetime satisfaction guarantee to lean on. We do not want the money of anyone who is not satisfied with what we provide.

 

Sounds like there was a lot of miscommunication via emails. I have a MM can system and I will say, it works well for me, no issues. It would be nice if the ports were marked, but I made labels for mine, so now they are marked.
