Hello,

Can anyone help me with something?
My engine oil is draining every 2 months.
I don't have any leakages and the oil that I am giving it is 5-20.

Can anyone help?
thanks

 

Your oil is going somewhere, so detective work is needed to figure out where.

You can get a rough idea of how much oil you're going through via the dipstick readings. Start with a fresh oil/filter change, check to see how much oil is on the dipstick and make a note of it. Check the dipstick every time you drive to see how much oil is remaining. This will at least show whether you're losing it all at once (not as likely) or a slow leak over time (more likely).

To confirm no leaks from the bottom of the engine/oil pan/drain plug, put a big piece of cardboard underneath the engine after you've driven the car and parked it. If anything drips out, that's your answer, or at least part of your answer.

It's possible that a valve cover gasket has blown. If you look at the engine from the top, does it appear that there are oil deposits anywhere? Might also be some blown oil on the underside of the hood.

More ominous would be major engine work - bad rings, blown head gasket, etc. Is there any whitish smoke blowing from the exhaust?

 

Has the car ever been overheated? Those aluminum heads on Hondas will warp causing oil to leak into the cylinders, sort of like a bad head gasket.

(If so, you'll see white/bluish smoke when you rev the engine).

 

Caused by a bad pcv valve on mine.

 

sounds like some shot rings to me.

 

I had a crankcase ventilation system hooked to the intake manifold (Volvo) that had too much vacuum. Plugs in #3 & #4 oil soaked. Brazed nipple shut then drilled smaller hole. Greatly improved. Was only getting ~160 miles per quart of oil on new car.

 

"Engine oil is draining" is imprecise and "every two months" is meaningless. How much are you losing over how many miles?

 

Four days since he posted...no answers from him.....

 

What were the signs your vehicle gave for a bad PCV Valve.

Wealth of knowledge here on PVC valve operation

To answer the OP's question, he should look to see if the engine's air filter is coated with oil getting sucked through a "stuck open" PVC valve.

 

 

I just posted this under "Bad PVC" and could apply here:

Well, if you start out with the proper oil level in the crankcase and you don't see any oil dripping off of the engine, the only way out is to the atmosphere is through the combustion chamber. Again, you don't see any oil spots on the pavement where the car is parked and/or you don't see oily residue on the bottom on the engine / car surfaces?

There are two routes to the atmosphere through the combustion chamber: in the old days, valve covers had "breather caps" that allowed crankcase pressure & oil fumes to escape but now that is controlled by the PVC system of valve & tubing that feeds back into engine intake at some location. OR, the oil is leaking into the combustion chambers around bad valve guides or bad piston rings. With the volume of loss you're experiencing, I'd have to say that there should be some oily residue on the surface of the exhaust tip if not "blue" smoke and/or the odor of burning motor oil if you sample the exhaust fumes with a "calibrated" nose.

Your spark plugs could provide some info. If they are black / oily then you know that the oil is being burned: bad valve guides, piston rings, PVC system. If only one / two spark plugs are black / oily then you can eliminate the PVC system because all spark plugs should be seeing the same amount of oil mist under that scenario. But a black / oily plug isn't good if you haven't seen the Check-Engine-Light (CEL) indicating a misfire. A misfire would say the the plug is bad, and if not firing, that cylinder could have weird pressure / vacuum cycles and be "sucking" oil past the piston rings / valve guides. All new plugs and possibly a new coil pack on the bad cylinder would fix it. Absent a CEL, that would indicate a bad cylinder system = $$$ because then it would be piston rings and/or valve guides.

Keep us updated, Thx

 

 

 

From your other thread:
Overfilling the oil is not good.
The engine may simply expel the excess oil leading you to assume there's a problem when in fact there is not, but at the same time overfilling it may be creating a new problem;

Overfilling can cause leakage, and overfilling can cause loss of oil pressure.

 

Matt & Henus, is your engine oil still disappearing?

 

 

Very odd that there's no sort of evidence that the oil is either leaking out of the engine, being pushed into the intake, or pushed into the combustion chambers and burned.
