SOURCE: 1992 Buick Regal transmission fluid getting into

Your radiator is connected to the transmisiom to cool the transmission. the tank in the radiator has ruptured and transferring fluid to where it should not be. solution replace radiator. This will transfer trans fluid to cooling system and vice versa. I can not see the trans oil ending up in the engine oil sump for any reason?

I have an oil leak at the end of the front driveline

when u say drive line do you mean the drive shaft for front axle and what side transfercase side or axle side and how bad a oil leak as it's normal for a slight wet look to be around the transfercase side shaft exit as this is all a "Wet" system and will seep a bit as things get lubed by oil in use , now if it leaves a puddle on ground thats too much and you should have it ck'd by a trusted mechanic (don't allow transfer case to go "dry") that would be expensive to fix then

No oil in engine

8000 over is not good. You lose some oil to what is called "blow by". This is when oil pushed by the rings around the pistons. This is a slow process but over time you could lose a bit and not notice any smoke. Also over time oil breaks down when not changed often causing a lot of it to stick to enternal parts of the engine which could be why you didnt get a light. Just some thoughts, sorry about your troubles

Had new distributor put 3 days ago , 200 miles , had a slight tick sound so was watching oil carefully, noticed was leaking worse than before, so I changed the oil to put new filter on, drove 4 moles...

  • Hi, for oil to leak that fast you have got a massive leak. The ticking itself could be from low oil. First check the oil plug (where you drain the oil) on the oil pan with will be the bottom most part of the engine. It is possible the plug is not holding tight, the gasket may be old, torn or just plain missing. Sometimes people will strip them oil plugs. When this happens the pan has to be tapped a little over and a new, slightly oil plug installed.

  • On the oil filter housing are oil cooler line that have to hold a lot of pressure. Follow those lines to see if they are leaking oil.

  • I don't see a front seal leaking leaking quite that bad. A valve cover I am not sure would leak quite like that either. Your oil pan gasket could leak like this though. When you check the oil pan plug look strait up to all them little bolt holding the oil pan to the lower part of the engine. If leaking is noted then snug them bolts up or have them snugged up.

  • You may have to throw a piece of cardboard on the ground and crawl underneath with a flashlight and get a better eyeball on the leak. What ever the leak it is massive and should be repaired before driving or you could loose to much oil and seize your engine. The ticking. in my opinion, is the engine telling you it is very low on oil as it is.

  • If you have any comments please feel free to leave them here.
  • Hope this helps and thank you for using FixYa.

have you checked the pcv valve ( positive crankcase ventilation ). plugged pvc symtoms-- can contribute to sludging of engine. it will build up pressure in crankcase if plugged. the pressure can blow out seals, it can also force oil past oil rings and burn oil up in engine. shake pcv valve, if it rattles its ok. if all else fails check oil pan gasket and filter also. ive seen holes in oil filters or they are loose. and upon driving, pressure is put on oil and it blows out.

Oil leak. Burning oil and leaving spots on the ground. Bad burning smell form the oil. Cant see any source from below.

If this is one of the front wheel drive v-8 models, there is a problem with the rear engine seals on some years. The seals open when the engine is hot and allow oil to drip. As the engine cools, the seals rejoin so the leak hides. Sometimes, all it takes is to retorque the existing sealing surfaces.
It may also be valve cover gaskets. The fan and motion of the car will cause these to run the dripping oil along to the rear of the motor like a rain gutter, then onto the exhaust and ground.

Losing oil, no visible leaks. 120,000 miles

Hm. In my experience if you lose oil at the rate of 1 qt. per 800 mi. it's going somewhere. Actually, if you lose 1 qt. per 1000 mi. and change your oil every 3,000 mi. it's under $10 in oil you have to buy to keep it topped off, and some places say that's there's nothing wrong.

But, your case is a little more serious.

I think that it's probably leaking past the rings and/or valves and the catalytic converter is eating up the oil, so you see no blue smoke, like you would in a car that has no converter (I'm assuming you have a catalytic converter on your car as my 1981 Honda had).

After 100,000 mi. little irregularities in the piston cylinders can develop, and seals can gradually degrade. So, this is normal for that kind of mileage, although there are people who get over 400,000 mi. on their cars with just regular maintenance and driving highway mi.

You might want to try one of those slower burn oils designed for cars with 75,000 mi. and above. That might slow the burn off of oil down to acceptable levels.

Good luck with it.

An oil leak that a mechanic cannot find? Find a new mechanic.

Okay, are you saying this is leaking a quart or more a month? That is a LOT of oil.
Oil does not evaporate. (Okay, yes, oil does evaporate, but so slowly that it is not going to be noticable in a vehicle). That said, the oil is going somewhere.

* Is it leaking on the ground? If so, then the oil will be visible the next day -- somewhere, either on the ground, or on some part of the frame. However, it will be visible.
* Is it a blown headgasket? If so, then the radiator fluid will be oily. Not good.
* Is it leaking into the transmission? Very unlikely, but in some applications is possible (not sure specifically about the 1999 Astro). However, this would be noticable as oil in the transmission.
* Is it blowing past the rings? If so, then the inside of the tailpipe will likely be sooty.

The oil is definitely going somewhere. I'm looking forward to hearing where!
