Reasons for Burning Oil

[amant02]

Hi Guys,

Another question,

My em1 has been burning oil(fair bit of it)

I just serviced 2 weeks ago and filled motor oil up all the way to the 2nd hole in the dip stick. Today before i started her up before coming to work i checked the oil and its already burn't 1/4 of the dipstick away.

There is no leaks. I have inspected the sump. Theres no stains on my drive way. Last week i thought it couldve been the rocket cover seal, as i found a fair abit of oil in my spark plugs when i bought the car. Replaced that with oem seals and no oil is found in there anymore.
Compression Test shows 195 191 195 191.

Theres no black/blue smoke coming from the exhaust. Is there anyother reason why my motor could be burning oil?

Im suspecting piston rings, is there a way i could test these without opening my block?

Regards,
Amant

What type of oil are you using and how many kms on the motor so far?

[amant02]

As its cold seaon atm, I'm using 10w50 Motul 300. As its gets warmer ill change over to 20w60 Penrite Semi

[curtis265]

2 weeks


but how many k's?

[amant02]

Two Full Tanks - approx 1000km? Give and take 50km per a tank depanding on the right foot.

Did you do a wet comp test or was this dry?

I'd do a leak down test now.

Plus degrease the shit out of your engine. Have it clean then check again for leaks after driving. Hard to spot anything with all that gunk around.

[curtis265]

hmmm

so 250ml/1000k


doesn't seem too bad.

Try inspecting your PCV

[amant02]

Whats wet comp test or dry?

If you mean the pedal to floor then yes and the engine was warm when I did the test.

These are the seals i got and replaced.

[curtis265]

wet is when you put oil down the spark plug hole to seal the ring

[amant02]

Then it was dry, but engine was warm i let it idle for 10 minutes before i did the test. So oil would've been present there? Not sure. I didnt drop any extra oil down the hole.

no noticeable leaks. no burning of oil. is this the first time you have checked it after you serviced it?, i know it sounds stupid but could it be that you checked the oil on a uneven surface and your just getting the wrong measurements.

[rhys.l]

Sounds a bit suss. Are you sure you completely filled it up during the service?

I thought I was having a similar oil loss problem, but it turned out to be nothing. After servicing the car and filling the oil all the way up (well, thinking I did anyway), I noticed after a week or so the level was now down to maybe 3/4. I thought I had lost a bunch of oil in a short space of time. I filled it back up to full, and the level didn't move until the next service 6 months later.

What I think happened is a combination of:

-oil level measured with car on different slopes
-bit of oil sticking around the engine rather than all going back down to the sump even when car is cold? Especially if you replaced the oil filter.
- Brand new oil sometimes being hard to see on the dipstick, making the initial estimation of level hard.

Anyway might be worth topping it up and giving it another run before getting too worried :thumbsup:

[amant02]

I tested on the same spot on my driveaway and its pretty close to being flat. I even service it on the same spot. This is how dad keeps a track whos car is leaking and damaging his property lol. I will go buy a new PCV next week. Thanks Curtis.

I did de grease the engine bay on the 1st day i bought the car, detailed the shit outa it. All the smallest stains i could find got removed.

I have topped her up again, thank god whoeva came up with that 5L oil bottle idea always a bit left over for top ups.

[curtis265]

^I'd say inspect it first - you should be able to hear it shaking around

[amant02]

Yea i just googled it. Guides say listen for a rattling sound, it should suck your finger. Or try putting a tick paper on the oil refiling hole and it should to try to the suck the paper.

But then again it should not cost more then $10 so might as well get a new one and replace the old one.

One way to check if your car is burning oil worse than it should, get a friend to stand on the side of the road somewhere safe/out of the way of traffic/people, then plant it past him in a low gear (2nd) and get him to tell you if there was blue coloured smoke.

if he says it had black/dark grey smoke don't worry it's just fuel. if he says it was letting out blue smoke at high RPM then your valve guides and/or seals are probably worn out.

[dougie_504]

Firstly you should run your car for a minute or so, or go for a proper drive, then let it sit for a few minutes before you check the oil. The oil needs to move around and warm up a bit before you measure it, or at least that's how I've always been told by my two mechanic friends.

Otherwise I would advise you try driving your car under high RPM at night with a friend driving behind you. If you're blowing smoke you don't always see it during the day, but at night you can see it very clearly in somebody else's headlights behind you.

If you are blowing smoke it's usually either the piston rings or the valve stem seals. Piston oil rings can leak and burn oil whilst the compression rings hold strong, so compression figures themselves are irrelevant. What's relevant is that you're supposedly leaking oil, so ignore those big numbers.

To test valve stems seals I was advised to coast down a hill in 4th gear, foot off the gas, then slam the accelerator hard at the bottom of the hill and any smoke coming out in that experiment would indicate stem seals. If not, then it's probably rings.


You using mineral or synth?

Have you maybe tried using some octane booster?

[Super-DA9]

I am interested to hear how octane booster will reduce oil burning.

Or is this a way to test pistons rings..?

But what are we shooting at here?

what could it possibly do? fuel and oil are entirely separate.

All y'all need to do is try it out. Y'all will be surprised what a little octane booster in with the oil can do

[amant02]

Well I'm against any fuel additives. So sorry mate. I rather rebuild then pour octane booster down my tank. Did u also know u can get 102 premium unleaded from certain outlets in Aus?

Okay, back to the topic. Today I replaced the PCV my god honda charged me $68.70 for the valve and $40/ea rubber hosing. Came with new clips thou.

Ill see how this goes.

Ill also do the testing recommended by dougie and da9. Thanks for the input guys. Ill get back to you after this weekend.

Replaced PCV and lines, Oil and Hamp filter today. Lets see if this works out. My one was still in good condition, so i don't think this will fix the problem. I just snapped it when putting it back in frigidity thing this PCV.

Forgot to add, Oil I'm currently using is Motul Turbo Light its syn 10-30, as its winter i have been advised to use thinner oil. When summer comes back around ill go back 20-50 semi syn.

Oh you mean mix motor oil with octane booster??

But why? What does the octane booster do to motor oil?

Just googled it. Didn't find shit.

If you have done this, link me a video lol. Very interested.

Just a heads up, you don't need to worry about the whole winter/summer thing so much. You should choose your oil weight by how quickly your engine is consuming it.

If 10W-50 was burning fast, 10W-30 is going to burn way faster.

[dougie_504]

How hard do you drive it? I baby my EH9 to 2,500 mostly, sometimes 3,000-3,500 if going up hills and I'm burning 0.7-1.0L in 5,000KM. Which is sustainable...

how do you know its 1l?

[dougie_504]

how do you know its 1l?

Because I put 3.3L in (as per the measuring lines on the bottle) then drain the old oil into an empty bottle to measure what I get back. Not perfect but a rough estimate.

[amant02]

Say i will hit vtec maybe once a trip, getting on to the motor way. Then baby it as much as possible. Highway normally sit at 3-4k Depanding on speed limit.

Normal roads would hardly hit over 3k unless its a steep hill, the s4c is a short ratio box afterall.

[dougie_504]

And never driven hard when cold? It's probably rings.

Get a leak down test I suppose.

[amant02]

Thanks for the input ya'll.

Just sold my other motors and got my tax forms from work. Looks like ill be rebuilding the motor.

Does anyone know how to get in touch with Adrain from TODA AU. Im very interested in that b16 130kw monster rebuild package they used to offer.

[dougie_504]

He's not in the performance business anymore. Working as a diesel mechanic I believe. Try to speak to Leo who distributes the TODA stuff now.

[stndrd]

Adrian is now working at SAS Tuning, but Leo at INT Distribution can look after all your Toda needs

Reasons for oil burning could be from a few main reasons;

1. Piston rings (You still may have high compression but that doesnt mean your piston rings are in good nick. Compression and oil rings are two different type of rings)

2. Valve stem seals - If you hit vtec too many times or have given your motor a really hard life, then dont be surprised to ruin these seals. If this is worn, oil will go to the combustion chamber via the valves..

3.PCV valve as stated - Check that. Open up your intake arm, open your throttle body and see if theres oil residue there. If there is, i recommend changing your PCV valve

4. - OR - YOU might not be burning oil, you probably didnt top up your oil after servicing your car. After every service, make sure to turn on your car for a few seconds then re check your oil level. (Oil filter takes up around 500mL of oil) So all up, from memory B series takes 4L - 4.3L ish? and of course check it on a flat surface
