So today I was going around a turn and my CHECK OIL Lv light cam on. Got home to find out nothing was showing up on my dipstick.........No knocking or crazy noises. Not good....??????

 

Is that a question? Yeah, never good when your engine is that low on oil. When was the last change?

 

That has killed many LS's.

 

Put oil in it. Duh.

 

Well obviously oil is needed lol. I'm trying to figure out what went wrong. I changed it 3000 miles ago.....Not good

 

LS engines use oil...I have had the low oil come on in my Yukon a few times right around 3k....mainly in the winter. I just add a quart or so and it's good to go.

 

You didn't check the oil regularly and it either burned or leaked the oil....I would start checking it 500 miles or every fill up. My 167K stock LS1 will consume about 1 qt every 2000-3000 miles or so and it doesn't smoke, leak, or anything like that.

 

I change it every 3000 miles and never really had an issue until after my cam install. I am thinking that the ventilation in the crankcase isn't right. Possibly is pushing the oil back up to my intake. I am going to put a catch can on to see if this helps my problem. But first gonna take intake and tb off to look inside my manifold to see if there is oil puddles in there. If not, i have another problem...

 

all engines use oil, it's the nature of the beast...

fill it up, and if there is no knocking issues you should be good.

 

When's the last time you replaced your PCV valve? If that gets stuck, it can result in increased oil consumption and reduced gas mileage. They are dirt cheap (like $7) and very easy to replace, and are supposed to be changed out every 30K but rarely are....

 

well since that baffle/pcv is under my valley cover. I never changed it. Car has 80k now. My guess is it went bad most likely. Although i did read these cars have a tendency to consume some oil and have blow through. I figured in that aspect i should get a catch can. But i think i may need to replace the valley cover pcv.

 

Lol no knocking or what have you. i put in almost 3 quarts.

 

It was 3 qts low?
I dont know how often you check your oil but you may want to think about checking it more often. Hell I check mine at least once a week, it only takes like 30 seconds.....

 

What car/engine do you have? My PCV is very accessible and yes my LS1 used some oil until I changed it. Now it barely uses any oil.

Does a catch can stop the oil consumption or Just catch oil?
In other words, will a catch can fix your problem?

 

I suggest a mighty mouse catch can to stop the stray oil mist from getting to the intake. It would also give you the ability to measure how much oil was getting through.

Another question - are your heads ported? If so, the rocker boss may be exposed, allowing oil into your intake runners. If this is the case, simply remove your rockers and reinstall using a thread sealer. Engine can drink a lot of oil this way

 

I'll have to check that one out. And no i have stock 241s. Only upgrades were springs, pushrods, retainers, and seals.

 

Ya I'm going to be monitoring it now. But i dont check it everyday or anything. Never really had a problem with any vehicles i have owned. Idk if my cam is messing with vacuum and causing pressure problems inthe crankcase and forcing it up. That's why i was looking into a catch can to stop blow by and to see if it was a source.
