Please excuse the fact that I'm a Honda n00b. I've got a highly modified A4 1.8t Quattro that I usually work on. My Fiancee told me she's been getting a flashing oil light lately whenever she corners.

I go to drain the oil today and only 1.5 Quarts come out! This is a 4.6 Quart engine! Can you guys please explain to me how this might have affected the VTEC system and any other damage you think it might have caused?

Note that I didnt see any oil leaks under there and she doesn't remember seeing any blue smoke. I guess whoever changed her oil last is a fvcktard.

 

i dont know much about vtec, but to my knowledge, vtec will not engage unless there's enough oil pressure, and a bunch of other things. so if anything, her car would bog down when vtec was supposed to engage. i dont think thats gonna cause any damage to vtec itself though. hope this helps.

 

sue the place she got the oil change done, I am serious.

 

Yeah VTEC wont engage if their is little oil in the engine, if she didnt hear any funny sounds the engine is probably ok.

If you think it sound louder than normal you have a problem too, otherwise dont worry about it too much.

You have most likely shortened the life of the engine, but at least its still running.

When was the last time it was changed?

 

i would have the car checked out immediately because usually when the oil light comes on ur basically screwed aka.. (blown engine, spun rod bearing etc). I know from first hand experience.

 

I did the same thing to my eclipse, no biggy it did fine ran good when i sold it 160,000k dont sweat it, engines are tough.

That's the question that needs answering. V-TEC motors burn oil, because that's how they are designed. If she is running the motor in V-TEC alot and doesn't get her oil changed regularly then it is very reasonable to assume that it burned it.

I had a lady come in in an '84 accord the other day with her oil light on. when the tech pulled the plug, not a single drop came out. She'd been driving like that for a couple of days and just thought she needed an oil change.

What part of the design of a VTEC motor causes them to burn oil?

worn out parts.

people think that h22a's (and coincidentally all vtec motors) automatically burn oil in vtec because the oil jets in the block shoot more oil through there (only in h22a and maybe f20b so i hear) and in an h22a where the sealing isn't as good, it burns. but bear in mind that there are plenty of h22a's out there that aren't burning oil.

 

****. double post.

Which parts?

the same parts that cause any engine to burn oil. any parts that originally sealed but now allow oil to slip by. think about it, no engineer would design a motor to burn oil. who would by a car that they new they would have to be adding oil in every week or so?

 

a well lubed motor will burn about 1 qt every 3000 miles...how long has it been since the last oil change?

So what does VTEC have to do with it then?

 

mine did the same thing. if you feel a loss of power or loud tapping ur fucked. i need a new head, bearings so im just gonna swap it out for a jspec motor. if no loud noise or u lost of power u should be fine and vtec wont engage if their is not enough pressure.

in the h22a and maybe in the f20b, there are oil jets in the block that squirt more oil into the cylinders when vtec is engaged. in an engine that isn't sealing as good as it did when it was new, some oil slips through and burns, and people mistake that burning at vtec as something ALL vtec motors do, when in all actuality, it's only worn out motors.

Do you mean the squirters that spray the bottom of the pistons to help cool them? They do that all the time, have nothing to do with VTEC.

rephrase: under heavy loads, on a worn out motor, smoke is visibly exiting the exhaust pipe, which gives people the idea that it is a characteristic of vtec motors to burn oil.

my point is that no motor was built to burn oil, in response to an above post.

So VTEC engines don't use any more oil than regular engines?

All rotary motors are designed to burn oil as part of the combustion process.

you are correct

and about the rotary motors, i stand corrected.
"no honda motor is designed to consume oil"

What about Hondas 2-stroke engines, like the motorcycles and small engines?
LOL

a motorcycle motor may use oil due to a high compression ratio and fairly high temperatures - very different than burning it.

 

Hey Chiovnidca are you just trying to be a smart a$$ or what. Yes a 2-stroke honda motor burns 2-stroke oil but he is refering to any honda 4-stroke motor and that they do not burn oil from the crankcase on purpose. Plus this is very far from the threads topic.
