Hey everyone,

I know a lot post similar threads, but if you are on the edge about getting a catch can and not sure if they are worth it, trust me they are definitely worth it!

Here is how much my Apex catch can has collected after just 7,000 miles.

Oil is not BAD for the top end of your engine(especially if some oil is getting on the valve and oiling the guide...
Just another money pit people like to try to rationalize.
Sorry I am STILL not sold.

If I wasn't spending money on my Camaro I would be spending it on something else. LOL.

I'm with you. This has been discussed at length before too. My conclusion (in summary) is -- if there was a problem, we would be hearing more about it. Direct injection is used in a lot of GM engines. The LFX alone is used in several model cars.

Exactly. There are a billion more "hey look what I found in my catch can" threads than "I had to have my intake cleaned and valves replaced" threads, despite the vast majority of LFX engines running around out there in the Camaro and other models, NOT having catch cans. Proof is in reality...

Wouldn't think with today's technology that you'd ever run into a engine design with poor oiling let alone see the benefit from the oil in a vapor. That oil was collected from that catch can in 7,000 miles, that amount isn't even a fraction of the oil that's been pumped through the top end of that rotating assembly in a few minutes.

If its man made it will have flaws and a failure rate. Just like with 350 vortec's with leaking manifold gaskets, looked great on the CAD program, but the gasket didn't end up being thick enough. No different then the GEN I small blocks and the not so great cooling design to the back of the cylinder heads. There's a reason why performance people in racing run water bypasses to the back of the heads. Just because something is produced, doesn't mean it comes without issues or flaws, but overtime it can be redesigned and corrected or it could meet whatever spec GM has.

The PCV system was not designed to help oil the engine. I think catch cans are a benefit, if not absolutely necessary. Aside from keeping the engine cleaner they can also aid in performance by reducing the negative effect of the crankcase gasses on the intake charge.

But you did hear more about it... that's why someone invented a Catch Can. OP's residue looks pretty clean, but I'm sure you've seen the disgusting photos by others, showing water diluted sludge coming from the cans. It has a lot to do with how you drive your car also, on how much crud goes back into the engine.

snymat68 · 04-15-2015, 01:30 PM

The only reason they vent the PCV back to the intake (and not to atmosphere like they used to) is because of EPA regulations. The EPA is not in the market of improving performance or longevity of engines. Quite the opposite it seems. A catch can is cheap insurance. Sure, nothing noticeable may ever happen if you don't have one, but why take the chance? I get peace of mind knowing that oil isn't gumming up my valves or causing increased carbon deposits. To me it's worth the few bucks of installing one.

I don't mean on a forum (anecdotal).

Catch cans are a spinoff from the racing community. Most of us don't need them. It's a placebo, something for companies to make/sell, and for bored hobbyists to buy.

I am not going to express my opinion of the value of these cans because I think the majority of you know, but the water diluted sludge found in the cans is a result of the can itself, and the condensation that builds inside it and then mixes with the oil. If the can is not there to collect the oil and the condensation, and then graciously combine the two into a gooey mix, it never happens.

Yes. Catch cans were born from racing, and the goal was to keep crankcase blowoff/emissions OFF of the track, since crankcase ventilation used to consist of a hole or tube coming out the side of the block, vented at the ground. It has nothing to do with engine longevity...race engines are usually torn down regularly anyway, and/or they see mechanical failure early from high engine speeds.

Is there any doubt there are LLT/LFX engines out there with more than 100k, 150k, with no catch cans? How many people are going to keep their Camaro that long?

And while we're talking about gases and other vapors entering the intake, why does nobody do anything with the LLT/LFX EGR system? (They route right back through the intake...)
