PCV oil catch can/separtor
Well, just got done putting on a Jeg's PCV oil "catch can" separator on my 2013 5.3L. Real easy project. Had it done in 20 minutes.

with this separator one end goes to the pcv and the other to the throttle body ? any oil getting by the pcv is captured in the separator and is not sent to the / thru the throttle body.
with this being a new vehicle did the separator catch any oil ?

You got it. This filter goes between the PCV outlet in the driver's side valve cover and the intake manifold. On the 5.3L in the Silverado, the inlet to the manifold is on the very top and not thru the throttle body like on some of the cars. Just put it on last night, so too soon to see any results.
Will see how much is getting caught by this system. Whether the vehicle is old or new, oil in some measure always gets transported right along with the gasses that are drawn up thru the PCV. Will post pics at various intervals showing how much is being caught. I am cognizant of the fact that this particular brand of setup may not do as well as I hoped. I am looking at a couple of other units if this one does not do well. There are several folks on other forums that have had excellent results from this one, so I decided to give it a try.

Decided to go out and take a pic. Put about 130 miles on the pickup since last night. Here is the oil the filter took out of the PCV system just in 130 miles......

Since they got brought up a few posts back, I would sure like to see the internals of the Moroso cans to see how they are doing their thing. Anyone got any pics to share?

Thanks for the info, it will be handy for me when I get around to doing this. Should the intake manifold be cleaned after install a kit? If so any recommendations? My truck has 48,300 or so miles on it. So I'm thinking there could be some real build up of crud.

That might be a good idea. I would seriously consider a seafoam treatment thru the throttle body and into the intake manifold. Maybe others can chime in and offer something better.

Just a thought for folks thinking of doing this, and wondering which unit is "best". If you are familiar with the "point of diminishing returns", it may never apply better than here. The Jegs unit, or a good quality air compressor oil separator, are about the same item. For our standard-or-slightly improved performance Silverado engines, they will remove at least 80% of the oil that the $180 Moroso unit will remove. With that 80%, you will not "feel" any improvement in performance, though your engine will run slightly better,and certainly run cleaner. If you pay the additional $130 or so for the Moroso, you have exceeded the point of diminishing returns. Maybe it is important to have "the best" at all times, and that is great. But, if that is not terribly important, and you are like many of us who do not have extra money to spend, you are not getting any bang for your buck by buying the best oil separator/catch can available.Las Vegas, NV...2001 Silverado 1500 LT Z71 Stepside X-cab, 171,000 miles, 5.3, cat-back duals, leveling kit, 3.73, 17" rims, more to come...
