It sounds as though you were low on oil, but not out of oil. Your MS6 requires around 5.5-6 quarts of oil, so if you dumped three quarts in to get it up to level, you still had nearly three quarts in it. While this isn't optimal, it's definitely not bone dry. This is part of the reason your oil light didn't come on. That and the fact most "idiot lights" don'...

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, ...

There's a very straightforward answer to this question: Water has a much, much higher capability to transfer heat than oil. Even if you were able to overcome the safety and design issues brought up in other answers, you'd still have to overcome the fact that water has a huge performance advantage at transferring heat compared to other common fluids (...

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 ...

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. ...

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 ...

When you visit your dealership, have them (and join in if you're allowed into the shop) examine the oil after it's drained. This is important to ask beforehand since some shops use a large funnel/collection tank apparatus that is placed under the car when it's on a hoist. If such a contraption is used, it's hard to view the oil as it flows, and it's ...

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 ...

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 ...

It sounds to me like you 'windowed the block'. When you lost oil pressure, you were at highway speed, so your engine was spinning decently fast, and every revolution without oil does more damage. I think the light noise was rod knock and lifter tick, the pop was the rod breaking and making a hole in the block, and the cloud was the oil that was left in the ...

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 ...

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 ...

To answer your questions, if there is a real leak, then yes, there is a problem. The oil will cause the belt to deteriorate and possibly slip. When it does, it is catastrophic. Pistons slam against valves and the head is toast (in most cases). This does happen suddenly. Get a different shop to look at it. If the belt appears dry, I would bet there isn't an ...

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 ...

My son had an engine failure on a 2015 WRX, same exact symptoms, connecting rod broke and punched through the engine block on the top side, breaking open an oil galley. 10K mistake after playing with turbo boost, ouch!

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.

If there was no oil leak before the oil change, then there is a possibility of wrong repair done at the workshop. Generally, for changing oil, the oil pan need not be touched at all, except for the oil drain plug. If the vehicle underbody is checked on a two post lift, then the leaking area could be spotted. Taking the vehicle to another mechanic is a good ...

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 ...

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 ...

Yes this is completely fine and what the dye is designed for. You should be able to get a kit at your local auto-parts store.

Thoroughly flush the diff and transfer box - then refill with the correct type and amount of oil. To prevent this problem - extend the breathers to either inside the cabin or the roof line. This was a standard modification on Landrovers that went wading regularly. The issue is usually caused by the air cooling and shrinking when the hot gearbox gets ...

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 ...

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 ...

New seals that are too large are unlikey to fit. You need one that has the correct internal diameter. You shouldn't need anything to hold the seal in place. You might benefit from a small wiping of oil to help lubricate it when the new oil cooler is put in place. How much did the seal cost you? Less than $5, I'd say. Just chalk it up to experience, go to ...

I work in a service centre - either the sump plug was put on finger tight and then the tech forgot to tighten with a socket or he didn't use a collapsible washer or the washer was faulty or depending on how much oil is on your driveway they didn't wash down the sump and the filter area after the service was complete. Either way they totally responsible. ...

Spray some brake clean in the plug well. Hold a rag over the plug hole and hit it with compressed air. You could also use a small tube and a fluid extraction pump. Or you could stuff rags down the plug wells until you get all the oil out. Also you need to replace the sparkplug tube seals (and make sure they're seated around the plug tubes) to keep oil from ...

The problem, in general, is that there is a leak between the lubrication system and the cooling system. There are only few obvious where this can happen: One is at the head gasket where oil can leak across the top of the head to the water passages (or into the cylinder or out the edge of the gasket) if the head isn't properly torqued of perhaps if there is ...
