Help?! billowing white smoke no overheat 2.0 si

So I realized after a couple days of putting in mew oil, that I had neglected to put my oil cap back on so for the past 30 driven miles oil was spewing from the head while my hood was shut.
I realized, gingerly drove to oreillys and put 2 new quarts in (all I could afford.) As soon as I left the parking lot and accelerated a HUGE amount on white/grey smoke came billowing ouuta , my exhaust. Yet there were no overheating changes and almost no loss of power. So I carefully drove the last mile of the drive home and parked.
I was revving slowly to see where the smoke comes from & I see it comes out from underneath the exhaust heat shield.
No ticking car still starts and idles regularly, yet theres almost no oil after the 1 1/2 mile drive even though I just put 2 quarts in.
Any help knowledge or experience will be appreciated greatly!

First off, you never want to drive your car when you know it's very low on oil...even gingerly. You should have parked it immediately and made arrangements to get to where you can pick up some oil. Not having enough money is not an excuse. If you can't afford to buy 4 quarts of oil then you probably can't afford to be driving. Nothing good can happen when you run an engine out of oil and keep driving it.

Sorry, I'm finished lecturing now. It's just the dad in me I guess.

You're gonna need to determine if it was oil smoke or steam that was coming out. It's possible that your temp gauge isn't working correctly, and the engine may have been overheating. Did you check the level before you added 2 quarts? How does your coolant look? Have you lost any? There's really no place under that heat shield that smoke can come out of unless you have a hole in the block or a hole in the exhaust manifold. Remove the heat shield and have a look. See if you can see anything obvious.

Im fairly sure it wasnt overheating, the radiator was full of coolant/water this morning when I gave the car a look. When I ran it in the morning it seemed to have no difficulty except when I took it around the block it smoked, yet less smoke came out. Later when I checked the oil it was well above the maximum level. Yet the oil light was, and has been on for the past week since I inserted oil in the beginning (then subsequently left the cap off.) So I drove it around the block again & the smoking seemed to have subsided completely

Drain it to the proper level. Well above is not a good thing.

Re: Help?! billowing white smoke no overheat 2.0 si

If oil was coming out of the dipstick tube because you added too much oil, that would explain why you were getting smoke from under the heat shield. The oil that came out of the dipstick tube was burning on the exhaust manifold.

Don't drive it until you have the correct amount of oil in the crankcase. Don't always trust your oil light (there's a reason it's called an idiot light). If you aren't sure how much oil is in there, simply check it with the dipstick.

Re: Help?! billowing white smoke no overheat 2.0 si

In the future check your oil when it's cold. If you pull into a gas station to get fuel, wait until you've finished fueling to check it. Let it all settle out of the motor. If you aint getting gas...wait at least 5 minutes. Could be why you didn't see any on the dipstick and now it's over full.

And along the lines of what Luzer was saying, coulda been the oil leaving your filler hole (while cap was off) ran down the exhaust pipe and when it got hot, burned...
I'll bet it staaaaaank boy!

We've all done that or similar at one time or another. That's why new cars come with the gas cap hooked to the car.lol

Mike, you think overfull could cause an oil light? Pump strain?

Re: Help?! billowing white smoke no overheat 2.0 si

Keep in mind it's an oil pressure light, not an oil level light. Could be a bad pump, could be a blockage upstream of the sensor, or could be a bad sensor.

No, I doubt it being over full would affect the light.

Exactly. But keep in mind that the pump doesn't make oil pressure, it provides flow. The pressure is created when the oil flows through the bearings, so another possible cause of low oil pressure is worn main or rod bearings. But my money is on either the oil pressure sending unit (sensor) or a bad connection/broken wire to the sending unit.

Re: Help?! billowing white smoke no overheat 2.0 si

^^ when investigating, go with the sensor first. Disconnect it, tug on wires to ensure they are still connected. Then shine a light into the clip to check for crud/critters, and if neither pan out get ya another one.

You can get a 3g service manual here, but the one at prelude3g is labeled a whole lot better.
The one here is missing the index page of each chapter. Makes searching a real pitb.

Re: Help?! billowing white smoke no overheat 2.0 si

Hey Luzer , If pumps provide flow Then why do pumps offer different PSI springs? They still have to have a pressure of more than 1 PSI I'm assuming? Some are 40 some 60 and some 80.

Re: Help?! billowing white smoke no overheat 2.0 si

I started to explain how this works, but then I remembered about this Eric the Car Guy video that does a very good job of explaining how oil pressure in an engine works. So I'll just attached a link to the video...
