The oil is most likely being burned by the engine. You should change your oil more often, it's not just new oil you are putting in, when you change your oil, it takes the old oil and contaminates suspended in that oil out. So by added 2 new quarts every so often is not nearly the same as changing the oil. Also I would recommend checking the oil level on a ...

I would be more concerned about whether engine oil is actually finding its way into the radiator from the engine. If it is, this would be indicative of a compromised head gasket, warped cylinder head, or damaged oil cooler (if the car uses radiator coolant for cooling the oil). The first two items are not trivial to replace or fix. The third one isn't far ...

The seller should not be selling the vehicle with oil in the cooling system. That supposed "quick fix" should have been rectified at the earliest opportunity. Have him flush the cooling system and put another few tens of kilometers on the odometer before you even consider such a vehicle. If the seller is topping off the radiator with oil instead of water, ...

I think Meineke was taking you for a ride (pun intended). Here is my reasoning: If it was leaking as bad as they say (or showed you) it was, you wouldn't have had any oil in your vehicle when you got to their shop. If the car was having the massive oil leaks all over the engine compartment as they showed you, there would have been VOLUMES of smoke from it ...

Yes, it's possible some of the seals designed to withstand water and glycol could get damaged I am thinking you are creating a fictitious scenario here, so I'll roll with it. If you filled your radiator with oil and started your car and let it run for awhile I would be most concerned with damage to seals that were designed to withstand water and glycol. ...

You can do a leak down test but look at your spark plugs first If your burning oil you will see it on your spark plugs. They will be black and have buildup on them. If you find one or two that look that way and all the others are very light in color to tan then you probably have oil getting into the combustion chamber. Here are some nice responses ...

Oil has a couple of places it can go. The ground The radiator The tail pipe It could be a leak that only happens under pressure (IE the engine running) but for that amount the underside of the car would be covered in oil and should be very obvious by looking under the car with a flashlight. If it's going out the tail pipe you would see obvious blue ...

Personally I wouldn't be all that concerned unless the oil leak was large. One simple check for the state of health of the engine would be to take the car to an independent mechanic and have a compression test done. It won't catch everything that could be wrong with the engine, but if the compression test comes out OK, it can provide you a bit more peace ...

The oil is going somewhere. If your vehicle is not marking its territory (leaking when parked), it's probably burning it.

I observed this same situation in my 1997 Integra back in the day. If you look at the summary on Wikipedia, you can see why the oil pressure is critical to VTEC: At the switch point a solenoid is actuated which allows oil pressure from a spool valve to operate a locking pin which binds the high RPM cam follower to the low RPM ones. So, without ...

It is entirely possible. Here is one of many videos on YouTube. Unfortunately, it is impossible to predict how much time or warning you will have before a car fire can occur. If you don't have the money to fix it now you should at least make certain that oil isn't allowed to drip directly onto the exhaust. I know the video may seem like the extreme ...

I'm wondering if you are having an issue with oil bypass, as in going through the breather/PCV and ending up getting burned through the intake. A simple catch can would prove this out for you. This happens quite a bit and is easily solved. Two things. The leakdown test will not tell you anything about your oil loss. Its not what a leakdown test if for (...

Not a desired answer, but with no leaks (to ground or into coolant) it's possible that your engine is just using/burning what some manufacturers would consider a normal amount of oil: How much is too much? Audi, BMW, and Subaru stick firmly to the statement that oil consumption is a normal part of a car’s operation. Subaru considers a quart burned ...

I think the likely suspect here is engine oil. If your head gasket is blown it is not unusual for oil to get into the coolant or the other way around. Coolant is being circulated through the engine very close to where oil is being circulated through the engine. Consider doing a compression test and/or a leak down test.

Oil leak is unrelated. You should fix that. (: There are various possibilities: The temperature gauge is faulty or the sender that sends the gauge the temperature reading is. Test: Block part of the front of the radiator with a piece of cardboard. This will force the system temperature to raise. Drive around for a little. Watch the gauge. Does it go to ...

What you have is the very same issue many Ford Escape owner's have: A leaking timing chain cover. My 2003 V6 is in the same boat. This is a small and somewhat annoying leak due to the fact it drips onto the exhaust and causes that oil burning smell and sometimes visible smoke coming from the right front side of the car. What I hate the most is shutting of ...

Valve covers are a popular leak spot, across all vehicle makes and models.

Even if there is a "common area" of oil leaks it wouldn't make sense to change a part based on the most common failure. You need to find out where you car is leaking so you don't make a needless repair that could easily cost you hundreds of dollars. I would get a second estimate on locating the oil leak. Dye tests don't cost hundreds of dollars. The "Dye ...

Certain Toyota engines are notorious for valve stem seal leaks starting at right around 60k miles. It's exacerbated by using synthetic oil. I put 180k miles on a 5S-FE engine that had that problem all the way from 55k miles. Just had to top off the oil periodically. The Toyota mechs I know all say it's not worth the money to fix, just monitor the oil ...

Gasket sealant is always good, but not necessary. Sealants are different, so ask the guy at your local auto parts store for sealant for the valve cover gasket. The difficulty levels vary with this, however. For example, I have an older Nissan Hardbody truck with leaking valve cover gaskets. The new gaskets are cheap enough, but removing the valve covers ...

I drive 2 1984 Topaz's and one 1985 Topaz daily. The part in your photo is actually the electric vacuum pump. It supplies the vacuum for the brake booster, cruise control, and the injection pump timing. Unplugging it was the cause of the smoke. The IP has a built in cold start mechanism that uses the vacuum to adjust the injection pump timing depending on ...

I take it the car is front wheel drive, being a 90s Toyota? If it is only leaking when parked facing uphill, then (logically) the leak must be to the rear of the engine. I would suggest that the driveshaft oil seals (where the shafts leave the gearbox) is a likely suspect. Where is the oil filter mounted? The seals around them can often be suspect. ...

Your oil pan gasket is probably leaking on one side. when you're on an incline, the oil is pooling on that side of the oil pan and subsequently leaking out.

An oil leak from the drain plug can be fixed for a few cents - it will just need a new crush washer on the plug (somthing that ought to be replaced every time the oil is changed, but rarely is). If it is leaking from between the transmission and the engine you've got a bigger problem, and one I would get fixed regardless of the fact it makes a mess, as it'...

Flush the radiator. Some of the red coolants, especially if they used dexcool will look like that normally. If you've got oil, or transmission fluid going into the coolant you will likely have coolant going into the oil or transmission fluid, so check those fluids closely for contamination. Once you've done that, monitor the coolant closely and see if the ...

If oil drips on a pulley or a belt then the rotation of those objects could sling the oil everywhere, even as high as the bottom of the hood. Most likely an oil leak would have to be above these components and a good guess would be through something like a failed valve cover gasket. Another possibility is that it is leaking near the front of the car ...

Unfortunately, oil consumption in these engines can be quite large. GM has put out service bulletins which says that engine use up to 1 quart per 2000 miles is perfectly normal. I found some information on the bulletin: (NOTE: - I was unable to find the actual bulletin, but the following is an excerpt from it, which was copied into the forum link I provided ...

Just reading this forum post, it appears your issue is a very common issue with your engine type. There is a main oil galley which runs right up through that corner of the head. This feeds the various parts in the head which need oil. The head gasket tends to fail right at this corner, so you'll see oil leakage. With that in mind, you'll most likely need to ...

I'm not a fan of RTV Others that are professional and hobbyists don't agree with me but, some do. I just don't use RTV, it's like duct tape to me. I get a physiological reaction to the acronym. I feel it has it's uses in very rare cases. Why don't I like RTV? Because if use too much it can create a bead inside of the motor and then eventually break ...

If it is the oil pan bolt holes that are stripped out, using a Heli-Coil thread insert is the professional permanent solution. Heli-Coil is the inventor of this repair method, but there are other brands now available that do the same thing, they are sold in most Auto parts stores here in the US. Using Epoxy to do this type of repair is similar to using ...
