Oil loss prevention

Cougar, are you running full VTA w/ MAF in stock location ? No stalling or richy rich ?

i was for a while, i now have relocated my MAF... before i was running the anti-stall vale kit on the synchronic BOV since its design has the valve open under vacuum. when i first installed the turbo it would stumble on shifts unless i was going balls out. after about 100 miles it got a lot better and would only stumble/stall if the BOV vented when i let off the gas completely and hit the clutch at the same time or was in neutral... same thing when i got the MSP ECU, took a bit to learn to adjust but it got better, not as good as the NA ECU did tho.


it runs 100 times better now that i relocated my MAF, the pig rich problem i was having around -10inHg anywhere above 3krpms dissapeared, which im blaming on my BOV since like i said the valve is open under vacuum, and a turbo will start making boost around 15-10inHg, so the MAF was seeing all that air but it was leaking through the BOV. and since i was able to remove the anti-stall valve my throttle response is awesome now.

well changed my oil today, found out that I was missing almost a full quart, even though it hadn't been changed in a year, but the miles were right on (because slug420 had it sitting for about a year or so when selling it).. I guess I should get the Milenia PVC to help with that right?..I will be installing the oil catch can anyways when I am done with school in a couple weeks, and I am not driving the car till then either, so would it still be needed?..

but btw, what exactly is oil blow by.. is that when oil "spits" out the PVC or something and into the intake mani? and how does the new Milenia PVC fix that?. heard a lot about it, just never sure what it actually was

normally blow-by refers to the piston rings going bad, they dont seal so the fuel air mixture blows by the rings into the crankcase, which is what the PCV is there to help get rid of. oil blowby can refer to the PCV system, either from the PCV valve itself or the fresh air inlet, ( the hose from the intake before the turbo to the valve cover)

oooh, ok.... so with the oil blow by, does any actual oil go anywhere and how would the Milenia PVC help with anything?
 
yes oil can go into your intake system, gets sucked up and burned.

well a PCV lets the pressure built up in the crankcase to be drawn into the intake manifold and burned. the millenia PCV valve is just built better and does not leak under boost which would be bad. oil can be drawn through the PCV valve into the intake manifold, you can prevent this by utilizing a catch can between the PCV valve and the intake manifold. you can also hook up up between the fresh air hose and the intake pipe
 
ah ok now I get everything.. so ya my plan is to order the Milenia PVC now, I'm pretty sure mine is good, but w/e it's only $20 and I don't want leaking, and the stock one doesn't seem to be held in there very tightly, and then I am going to stick the oil catch can in between the PVC and the IM, and I have a breather to put on the valve cover which would normally connect to the intake pipe.. and just plug off the intake pipe.. think I should be covered then(first)

if your not going to use a catch can on the valve cover breather i would just leave it connected. under boost the PCV valve closes so the PCV system works in the other direction, blow-by gases are sucked into the intake pipe through the breather tube. if you put a filter on there, there would be no vacuum to pull the gasses out. but this is debatable as you can see a lot of people put breather filters on with no problems. if anything using a breather filter would cause you to fail emissions since the gasses are venting to the atmosphere.
 
hmm, interesting.. ya slug420 had a breather in the car when I bought it because he had a SRI in there, I can get the emissions testing done before I install this (which hopefully my dad brought the car down, the machine was broken before but I need emissions soon lol) but as far as problems, a breather shouldn't really cause any problems right?, I don't care about emmissions really, once I'm pass them this week, I will worry about them the next time, but wouldn't the breather prevent the oil from being spit into the intake and thus the IC, which I really don't want, because I have seen little streaks in my IC pipes before where the couplers are from oil, not a lot at all, and I had my turbo seals replaced with my first car and I had still seen it, new car I haven't really looked at it that much. and I heard that the oil catch can in between the IM and PVC is more effective and than you can just put the breather on the valve part and be covered.?
 
Before my engine rebuilt, I got blue smoke, and my PCV valve easily got full within 100 miles driving. Crazy, rite? I couldn't take it any more, so I just decided to fix the engine, and rebuild it. It's ok now.

Yep, The supercharge ruined the piston, piston rings, rods, on the factory built engine... cuz it's not strong enough to take that much power...
 
hello I had the same problem on my car somehow I was running out of oil and every mourning I started the car it was smoking and i was wondering what was going on. and i also had a fuel cut and 4000rpm.
so I decided to change my pcv valve setup I removed the mazda setup and bught some hoses that would fit the pcv valve and bought a see through gas filter and a t adapter and installed it and at the moment I haven't lost oil and my fuel cut desapeard
 
I have a quick question, I have been back firing a bunch, this is the first time I have noticed it before, and I have a Cat, and it is still semi loud sometimes, it actually caused a CEL for too lean from the back fire.. which I assume is might be a miss fire? or what, since I installed the 626 IM the AFR's have been leaner but I didn't get the back fires until after I installed the catch can, and the Milinia PVC valve.. anyone have any ideas?.. do I just need to tune it.. but then again it happens out of boost as well as in boost.

when does it happen? all the time, accel, deccel?

did you touch your crank pulley, crank position sensor or cam position sensor? back i had my crank position sensor go out on me from coming in contact with the gear on the pulley throwing it off center, it caused all sorts of pops and gurgles cuz the timing was off.
 
where is the crank sensor?.. it is possible but I don't know, if those ar the ones that are inside the valve cover casing than no, but it happens when I let off the gas, and when I am driving and maybe just let off the gas a little before resuming speed or accelerating, and also when I deccel.
 
I think most of us will agree that the oil system of our cars just absolutely sucks!! I've been burning through 1-2 quarts of oil between oil changes every 3-4K miles, and I don't have any leaks. Compression is also fine on all cylinders.

What can be done to improve the oil system and prevent oil loss? Where does this oil go?! I know I'm not the only one having these issues, so please share your opinions.

You guys figure it out yet? It's considered normal by the manufacturers to go through up to 1 qt every 3k miles. More than that and there is something wrong. I think that there is a lot of lose in the turbo. I've seen a lot of bad turbos on perfectly healthy cars, some people are already on their 3-4 turbo.
 
I agree with others. As far as preventing the oil burn up, it starts with preventing driving a car like a fast and the furious audition. Ive noticed that the few times I decided to get on the car were the few times it burned a lil oil. I usually stay blazed keepin me in a chill mode therefor driving my car as intended and not a drop of oil is lost! Try it out sometime, as it might be no fun consider it car science....drive like a grandma for the next 3k and see how ya do. Either way good luck

That's easy to say now, wait until you install your turbo kit ;)
 
hrm... My car doesnt even appear to be burning oil between oil changes even with a small oil leak at the turbo. Well here recently that oil leak has gotten bigger so you can smell the oil burning when you park the car.

I have no problem. Grant it I do go into boost a little but driving like a normal person isnt hard to do at all. I don't shift at redline every shift. I do get on it from time to time and normally shift aroudn 3-4.5k depending on which gear I'm in and conditions obviously.
