You should talk to @Chris Draper he blew out his RMS because he plumbed his catch can wrong and it was whistling like a freight train every time he drove it.

 

I don't think you have enough experience judging from the OP to make that statement.

You are not driving a race car, nor making enough power to be running your catch can the way you are, but that's just my opinion.

 

I agree and I get that. It’s not high horsepower I’m just trying to use what I have (cheap can I was given.)
Let’s take a step back here.
I understand that. It’s not a “race car” it’s essentially cam only car that I use on the track a handful of times a year and it’s used on rallies

I just have a different approach to this. I’ve seen a lot of different approaches to this over the years.

let’s take a step back and look at the meat and potatoes of the LS1/6 PCV system. No beef toward anyone. I’m just gonna talk here and let’s take a look at this objectively.

LS6 I’m referring to:
-the line from the TB is a ported vacuum line
-the line from the intake to the valley on an LS6 is an updated version over the LS1 style that took crank fumes from the valve covers but it was flowing too much and ingesting a lot of oil itself so they updated it on the LS6 and up.

after whatever year, the EPA and manufacturers wanted you to “ingest” crank case fumes to reduce emissions. So they started using the engines vacuum sorces to breathe this back in. So here we are.

Ported vacuum will draw in air from the valve covers under throttle. And not when it’s closed.

Manifold vacuum will draw fumes from the cam valley when the throttle isn’t used.

the valley can breathe in or out as it needs to as can the valve cover which is still letting the crank case breathe.

all I did was block off the intake side of the deal. Crank case pressures can exhaust through the filtered catch can. If the engine needs to breathe in, it will have filter to make sure it gets clean air.

I agree it’s not a 1500hp engine that pushes a lot of fumes on the two step.

I’m not trying to be argumentative but I think some are missing my point of what I’ve done.
the car hasn’t smoked since. But it might have been some oil blowing off the front from the recent power steering pump swap.

I might just get a new LS6 PCV line since mine is old and loose. It was off during the winter build. The catch can in my experience catches some oil vapor and mostly condensation but LS engines do breathe a lot of oil vapors back in that’s why the intakes are often a mess when we take them out.

that’s all I’m doing. 🤷🏼‍♂️
so I’ll apologize for being defensive. Let’s look at this from a different perspective.

 

OP: your can is routed correctly, no need to worry there. Let me explain:
-Valley port is under vacuum with the OEM setup. More specifically, it's under vacuum under all conditions except WOT, where vacuum is near zero and the blowby will flow into the intake manifold under its own pressure.
-Passenger side valve cover port is typically a fresh air intake, to allow air to flow in and out the valley port under all conditions except WOT. On a stock PCV setup, blowby and oil mist will exit this port and place oil into the intake manifold at WOT - this is because blowby mass flow rate exceeds the valley port cover capability. This is why a sealed catch can is needed - it will capture oil mist and allow the PCV system to operate as Chevrolet intended.

Your setup essentially removed the PCV system that routes blowby back to the intake for ingestion and thus emissions. It will allow blowby to escape under all conditions to the atmosphere and will not ingest air because the crankcase is under positive pressure at all times, from cylinder blowby. The engine will not consume any blowby or oil vapor with this setup, nor will it be possible to damage it in any way. The valve cover and throttle body ports are sealed with vacuum caps, so no harm there.

That said, I think your blue smoke phenomenon may be oil that was pooled in the intake manifold prior to installation of your TPS can. I doubt it was valve seals, and since you didn't notice any more smoke after the initial observation, it wouldn't be worn oil rings.

 

It’s great that someone is finally helping the OP out with some actual useful information. You Sir, are a gentleman and a scholar.
