Quick question about OCC VTA

[Speedracer69]

Hey guys so I installed my OCC from JBR it's the stage two with the check valve and I'm having a pretty big issue with it, I followed the directions from the JbR support page and I'm having a bunch of smoke from the exhaust. My turbo is brand new bought a bnrs3 so I doubt that is the issue. Also I made the check valve is facing towards the catch can and away from the pcv. Has anybody else had this issue? My oil level was basically drained because the OCC was venting out all my oil from the VTA filter. Luckly I didn't mess anything up because car drives fine besides the huge amount of smoke at low rpms and at stop lights. Any insight is much appreciated thanks a lot.

Your oil is going into the intake from the catch can and is causing the smoke. Plug the intake mani nipple and just run a hose from the pcv plate and if you want to the valve cover breather to the occ and you will be fine.

Thats how its wired, i followed the instructions from the website. I thought it could of been that but no oil in my turbo or intake or intercooler piping

It's wired like that. Intake mani and intake is blocked off, valve cover runs to the top of the T which connects with the PCV to the bottom port of catch can and then the top port on catch can is obviously the small k&n VTA filter

You may have a bigger issue here if your oil level is dropping that quickly. The OCC shouldn't be getting THAT much oil through it.

Then its not the catch can if it has no way of going into the intake side.

Might try out a compression check.

[MattyP617]

any loss of power? I'd do a compression test. weird issue

[btstarcher]

Might see if the PCV valve is stuck open.

[Speedracer69]

No problem feel great, freek never mentioned anything weird before catchcan so I'm not sure what the deal could be, I thought about it being the pcv just sucks I have to take the intake mani to replace such a small piece

Also my oil never drops that quickly when I don't have the catch can the reason it's getting drained so quick is because the catch can is sucking it all up im assuming( possibly through pcv) like mentioned above.

[btstarcher]

OCC doesn't provide any vacuum; that's why it's connected to the intake manifold. You shouldn't see any difference in oil consumption.

Can you draw a diagram of how you connected it and where the check valves are?

[Mattyhawk1]

Recheck installation, per JBR instructions, Pg 7, #14 sounds like you installed the check valve incorrectly.

That's not VTA, check the VTA installation (fine print in red) I've had it connected both ways and either way still does the same thing

[Speedracer69]

This is how it's routed

[btstarcher]

Why would you have a check valve inline with the PCV valve? They do exactly the same thing. Something is wrong.

[Speedracer69]

That's how the JbR has it instructed man

[btstarcher]

My opinion, it's a shitty way to route the OCC. You've removed the source of vacuum from the equation by blocking the IM port. In order to properly run a vented can, you need 2 OCC's: one sealed, between the IM and PCV valve, and one vented, between the VC and either the TIP of a slash cut into the downpipe (to provide vacuum under boost). My guess is that the oil is coming from the valve cover under boost, because there's nothing to pull it from the crankcase out of the PCV valve.

Get rid of the VTA setup and run it as a sealed can.

The valve cover hose was bone dry so I don't think it's coming from there, the check valve on the hand drenched in oil. Maybe bad pcv? But wouldn't the check valve stop it? I know a guy running it the same exact way on his speed which is why I decided to do it because he hasn't has a single issue. I forgot to mention I ran a corksport with the way your saying to run and had the same thing happen as now would get full within 50 miles of driving so I removed it and cleaned out all my intercooler piping and intercooler because they were covered in oil. This time it's a little different because I don't have a hose routed to my intake so that's got me mind baffled.

[btstarcher]

It would have to be a bad PCV, because there's no vacuum source connected to it, yet oil is getting passed it.

[ASHMS3]

@jbarone; take a look and help this guy out.

That's honestley my best guess as to why it's happening, my problem is understanding why the oil is being burned off by the exhaust if there isn't any trace of it in the intake or turbo?

Quantify what a "bunch" of smoke is. Are we talking same as a smoking K04 here?

[Z32_MS3]

So you had no smoke before the catch can and now you do hmm. There isn't any reason a catch can would do that. I'm thinking bad PCV too especially if your valve cover hose was dry

[JBR]

Not sure...even if the PCV was bad he has the CV there which is pretty much the same thing.

He indicates he had another OCC installed and configed the same way with the same issue. It's something else but what?

edit:
Try reconnecting the VC to the intake and running the line from the PCV with the CV direct to the lower port on the can and leave the breather in place.

[JBR]

How many miles are on this car and is the motor built?

I'm talking about car caught on fire smoke, or like 2 bottles of seafoam, at idle lol

[Speedracer69]

Well I took the catch can off and ran the car the stock way valve cover to intake and intake mani to pcv. Car stopped smoking, but car doesn't feel 100% so I know that the issue may be elsewhere. The car has 88k on it and it's fully stock besides basics 3.5 JbR intake, autotech fuel pump internals, bnr s3, Catback exhaust no cats, pretty much it for performance parts. Before the valve cleaning and JbR manifold TIG and throttle body TIG and egr delete primary and secondary car ran great. I'm currently tunning with freektune and he never mentioned anything strange. I feel like the car shouldn't be drivin hard because it's stalling now. Only codes im throwing is egr, and secondary O2 sensor sometimes.

[JBR]

I think a compression test is in order. Sounds like massive blow by.

Anyone else want to chime in here??

That's what me and a few of my friends were also thinking. Car just stalled driving home a few minutes ago going into light boost in third gear so just because no smoke doesn't mean all is well. Just strange that it would do all this after car was running perfect before all this happened. I guess when my engine starved from the catch can stealing all my oil must have screwed something up internally.

[JBR]

Unless you lost all the oil internal damage is unlikely. I'm guessing fouled plugs from oil.

[Speedracer69]

Yeah I'm not sure but my oil level was basically non existent on the oil dipstick. I sill haven't checked my plugs but I will get around to that and a compression test as well

[hatchedspeed3]

@Speedracer69; check that PCV immediately. I had the same fucking issue, and it ended up eating my motor....dont learn the hard way like I did. are you seeing oil in any places it shouldnt be when you dont run the can?

I already prepared for the worst I know motor will probably need to be rebuilt so just taking it one step at a time to figure out this issue. I haven't found oil anywhere else, where do you think I should look? My intake is clean, intercooler/pipes are clean, turbo is clean. Did you ever figure out what made your motor pop?

[Speedracer69]

Ok so just got done doing my compression test, the spark plugs looked good IMO, the compression test wasn't the worst thing ever either. I got 185,180,180,180 cylinder 3 I added a little oil because it was at 165. So maybe an issue with cylinder 3?

[Speedracer69]

Here are the spark plugs

[ASHMS3]

Leakdown sounds to be in order as well.

Using bad grammar from my cell phone.

i do believe the pcv valve took a shit on me, wont know for sure until this weekend though.

Let me know when you find out man.

[hatchedspeed3]

judging from all the oil around it, and in the can, Id say thats what it was. Then again, I also had oil in my intercooler, intake, etc, etc

[Speedracer69]

Here are the results on the leak down. The percentage of leak in the cylinder number, where I coukd hear the leak and the last two spark plugs had very light dark black oil around the threads.

You had a catch can on at the time when it blew? I don't have any oil anywhere, also how did you have the catch can routed?

[hatchedspeed3]

i had it routed the same way yours is supposed to be routed (see directions). mine is a Kozmic can though, with a vta option. The vta option was messy as fuck, so we sealed it off. Oil consumption dropped and car rean better (weird enough). Complete pain in the ass. It came on the car, otherwise I would have run JBR. @jbarone; makes awesome shit
