I think that I have an oil consumption problem.... heres the history: rebuilt motor, honed, re-bearing'd, absolute stage II heads, 222 224 571 574, 114LSA cam, forged rod bolts. Stock tune, runs great. Well last week, my low oil light was on. Oil pressure was still at 60 while at about 2500 rpm's 40 at idle. Checked the dip stick, and it was low. Put a quart in it, and the light went off. It happened again last night, low oil light, put half a quart in it, now its fine. Oil Pressure is still fine. Will tuning solve this problem or is it more PCV related? All of the smog crap is off the car too, smog pump, EGR valves etc. The motor has about 2700 miles on it since re-build. I used non synthetic oil 10w30 for the break in (500 miles) then switched over to Mobile 1 10w30 synthetic. Anyone have any input on this? Thank you in advance for any help.

Well I just ordered the breather for the oil filler cap. I am going to do away with the PCV all together, see if that works.....

 

ttt, anyone on this subject????

 

How many qt.'s did you pour in? LS1's tend to "lose" oil.

 

well orriginally, with the oil change at 500 (after rebuild) I put 5 1/2 quarts in. Then the first time I noticed the low oil light, I put a quart in, then the 2nd time I put half a quart in. I ordered the breather for it yesterday, hopefully that will help it out.

 

Hopefully that breather will help out...your right. I need to do the same thing. That is why i chimed in to see what you were going to try.

 

I will keep you updated......I have a couple buddies running the breather, and they said it helped out. I am sure that when I get a tune, it will help out as well....

 

Cool, let us know how it turns out.

 

what is an oil breather?? My car has been sucking oil like mad lately. its not leaking...that i can tell. my change oil light came on a 2000 mi. I dont know if this is normal for these cars but it was really early and i dont run the car abnormally hard.

 

It is that breather filter that goes in place of the oil cap on the passenger side valve cover.

 

you can also eliminate the PCV valves completly as well by taking all the lines off, and putting another small breather on the drivers side valve cover.

 

Yeah, I have seen both. I was giving him a mental picture of what we were talking about.

 

LOL....yeah, its hard to describe....wish I could find pics of it. I could always go take pics of my buddies car too

 

That might help actually.

 

I will see what I can do this weekend....

 

LOL yes rob you can take them sexy pics of my car LOL. all so rob to a search that i reamber a while back that ppl running mobil1 syntetic oil was loseing and they changed ot other stuff and all so helped

ok here is only pic i chould get before camara died

 

Is it just me or does your breather look really tall?

 

thats how it sets, on mine and on anouther friends car

 

Thanks for taking that pic for me Eddie, I appreciate it. I was gonna take a pic of it on Sat if you came out.......thanks again...

 

You may also want to try a catch can. You would be surprised how much oil can be ingested into the intake. Take a look at the back of your throttle blade to see if you have any oil on it.
