B16a2 Burns oil?

[im.Kusuma]

Hey guys,

Noob question... Just went for a drive on my bros EG..
I was checking the dip stick before i drove for daily check ups.. and i found that the oil was half way instead of full.. My bro dont vtec as much as me or probably he doesnt vtec at all..

My question is, on daily basis of driving, what makes the engine burn oil? There are no oil leaks because all gasket has been changed everything seems clean, even the oil sump and etc. And after i vtec'd it.. Oil level decreased to a quarter :o ...

Any internal things i should be aware of or that needs to be replaced?
Engine has done 160,000km approx.

Mods are just CAI and spoon cams and forged pistons with new piston rings replaced..? :o ...


thanks in advance

Does the oil blacken up ? Or just lose oil ?

hmm on the dip stick its pretty dirty.. Needs service soon.. but i was wondering if this happens to other b16's.. On my GL, it doesnt need to be topped up at all...

Did you drive it then quickly checked the dip stick after the drive or waited for the the oil to settle in first ? I just find it unusual for a car to chew oil as only a 2 stroke only really does need to chew oil.

i took it for 30mins drive. Went to my mates place and it was 30 mins drive. Only vtec'd it once, didnt drive like a moron...

I waited till it cooled down for approx 15mins.. then i randomly checked it again to see..

I find it unusual too.. My carby's done 280,000km and it doesnt chew oil at all.. even though i drive like a dickhead sometimes

Last time i checked on my older brothers type r. He also had cai ..before he had it the oil was fine but after installed it seem to suck dry alot of the oil.

So my only suggestion was the cai that did that, maybe you can check that out

Its not the CAI.

Check the oil when its cooled down completely, this is what you go off. When you heat the engine up the oil heats up and becomes thinner, it then moved around the engine to lubricate it, thus looking like the oil is being chewed and spat out somewhere.

what oil ur using?

New or old oil?

[im.Kusuma]

new oil man lol it just recently seviced.

Yep, will do. Thanks for your input.. I cant really try this now since i topped it up already lol

as mentioned, what kind of oil are you using... you mentioned that it is due for a service, then said its just been serviced?

When it was serviced, was the oil level higher? if so, how much higher?

When driving does it blow smoke? white smoke?

[niiCk]

yeah its funny how youre contradicting yourself-.-
youre full of it man LOL..
use better oil(Y)

Serviced as in few thousands kms ago :o sorry

Oil level was right wer the second mark is.

Im using castrol GTX 10W-30

No it doesnt blow smoke at average driving, but when fully throttled, it blows smokes but not much, just a tint of white smoke

EDIT - last serviced was around 3500kms ago so im assuming it needs servicing soon?

Full of what?
Shit?

sorry im not familiar with the dipstick on your car... what is the second mark? how many marks on the dipstick? how far down the dipstick has your level reduced in the space of a few thousand km's?

So if you are blowing white smoke it means you are burning oil... you said you have new pistons and rings? have you done a compression or leakdown test? given youve just replaced the rings i would have to say the compression is right unless you have a valve problem...

there are 2 marks. One is for low and one is for high (just right)
Usually it just by a tiny bit between the 2 marks, maybe just around 2mm below the high mark between the previous servicing to the next, but this time it has gone more than normal. It has gone to a the low mark.. :o

yes i did, we changed the pistons so im assuming pistons arent related.. And no i havent have the compression test. Do you recommend me to do so asap?

Engine has a tappet adjustment problem (was told by previous owner) but i believe it has been fixed on the previous service..(i wasnt there so i cant be certain)

I will double check with my mechanic regarding the valve.

Thank you for ur input

[Zilli]

is it at the half mark or the low mark mate?

In the first post you said its halfway?

Anyway, best of luck with it, take it to a mechanic

hmm yeah thanks

could be blow-by, clean the PCV valve, or replace it.
That should help.

If its the rings your gonna have to run thicker oil in it.try a 15w-40 or something, cos it will seep past the rings overnight.

how does blow-by affect oil?. sorry to hi-jack thread but just wondering

[aaronng]

GTX 10w-30 is a very cheap mineral oil that does break down when under high temperature, like in modern engines. That could be one contributing factor. The heat causes the lighter fractions of the oil to turn into oil vapour, which is removed through the PCV system into the intake manifold. After a few thousand km, your oil level will be lower and the oil will also seem a bit thicker.

The other is like others have said, blowby. Blowby is caused by the combustion gases blowing past the rings into the sump area. The wall and rings are lubricated by engine oil and the gas being pushed through will pull the oil with it and then out through the PCV system into the intake manifold where it is burnt.

thanks for the tip! I will try using different oil :)
Rep point has been given.

Lol its ok, i dont even know whats a blow-by is :o lol

I explained what blow by was in my post. :)

yeah i know lol i jst replied gsi-psi on it.
But yes, i do understand it now :) thanks

clean the PCV valve with throttle body cleaner, check that the one way valve is working (it should rattle and only blow one way) then....

try running OEM oil first. If it still burns try going up slowly, 10w40, 15w40.
And at worst 20w50 which is pretty much means your rings are gone.

Other method i used on an oil car that worked was OEM oil + Lucus Oil stabiliser (about $15 from supercheap)
Gave the car another 3 yrs before my other sister crashed it

[Limbo]

P.S its a 1.6ltr vtec, everyone gives them heaps cos its the only way the make power, but alot of people don't maintain them right. A high revving motor always needs more attention

[im.Kusuma]

thanks for your input Hao, :)
very appriciated

That makes the engine oil very sticky though. Turns it from a cooking oil consistency to that of caramel! Also makes it prone to foaming.

i should have added you only put abit in, like about 100ml or so.
I've never seen it foam though. Worked for a few of my cars once they started burning oil.
