Most likely cause is a worn or misadjusted clutch. The clutch disc is slipping meaning that all the engines power is not being transmitted to the transmission. Cost of a clutch replacement is to varied to give an accurate estimate. Clarification Note Energy will always take the path of least resistance. From a clutch's perspective, it is much more ...

The short answer is that yes, you will still have to change your oil. As you say: in jet-engines, where the oil is sealed [emphasis added] The oil is not sealed in a car engine and, even if it doesn't wear out very quickly, it will still become dirty. Car engines and jet engines are very different beasts. You might be surprised to learn that some ...

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 ...

Go with the recommended oil. The manufacturer should know much more about the vehicle they designed than your mechanic friend. Here are the factory recommendations for the E34. This covers all engine options that were available for the E34 chassis. Viscosity : Cold climate: 5W-30 Mild climate: 10W-30 Warm or hot climate: 15W-50

Sam, Chemistry isn't my strong suit, but when it comes to synthetic then no, they are not created equal. I know you're not looking for a shopping recommendation, and I can't give you one anyway. What I can say is that the additives the manufacturers use are selected for different reasons (high temperature additives for races cars, different additives for ...

From your description it is a bit unclear what the problem with the drain plug bolt is. I'm assuming that the hex head on the bolt has become rounded, and as a result your wrenches and sockets are slipping on the bolt head, preventing you from removing the drain plug. If this is the case, you can try welding another nut or bolt onto the rounded drain plug, ...

tl;dr: This procedure checks the oil "reserve" remaining in the pan after all moving parts are lubricated. This procedure is purely vehicle dependent. For example, on my car, I'm supposed to check the oil when the engine is cold. In asking you to check when the engine is hot, the oil will not be pooled in the oil pan. Instead, it will have been fully ...

This is normal behavior - When the engine is not running, there is no oil pressure, so when the ignition is turned on, that light will be on. As Larry says, this functions as a bulb test so that you know that it is working. When you start the engine, the oil is pumped round, the pressure goes up and the light goes out.

First, the driving style that you described certainly places less stress on both tires and engine oil. You avoid hard braking and hard acceleration. This puts less wear on the tires than someone who brakes and accelerates hard. End of story. By avoiding hard acceleration, you put less heat into your engine than someone who accelerates at full throttle, which ...

If coolant is getting into the engine, then oil will be getting into the coolant. It's a 2-way street there. I'm really surprised he didn't mention it, since it's expected. However, normally after doing a gasket repair of that type they just automatically change your coolant and oil on the spot since it's contaminated.

Bank 1 on your 3800 Series II Engine would be the set of cylinders that is closer to the front bumper of the vehicle (cylinders 1, 3, 5). Bank 2 (cylinders 2, 4, 6) would be against the firewall. The Leak... Any vacuum-leak hunt shouldn't start without having a clear vacuum-hose diagram in-hand. There should be one on a placard inside the engine bay ...

If you look at your engines dip stick you will see minimum and maximum marks on it. The engine oil level must be maintained between these marks, any cause that means that this is not the case must be rectified. Carry a can of oil in the boot/trunk for topping up. The engine oil lubricates the moving parts, cools internal parts of the engine, and operates ...

The only scenarios that comes to mind is lots of short trips where the oilpan and oil never got really hot. Then 35 days later a long trip gets it really warm and the plug gets loose and falls out. The second is a defective crankcase ventilator along with a damaged plug "O" ring that eventually blows out resulting in a loose drain plug. Both scenarios would ...

Does the white smoke smell sweet like antifreeze? The loss of power plus the white smoke points directly at a bad head gasket. They don't last forever and it sounds like yours just got used up (coincidentally right around the time that you changed the oil). Head gaskets on those VTECs can be replaced in your garage. However, I wouldn't recommend the job ...

General Motors has a similar system in my 2002 Silverado. The way I understand that it works is the computer looks at a variety of inputs to determine oil life. It looks at engine load, cold start cycles, engine rpms, conductivity of the oil and some others. I know in my case it works as advertised. In the summer the engine reaches operating temperature ...

This vehicle in your example photo is a really good example for when not to use an oil drain valve. Notice the heavy lugs on the all terrain tires? I am not sure if this vehicle is 4 wheel drive, but the tires indicate it the owner plans on driving on other than smooth paved highways. A drain valve on an off road vehicle, is an invitation for a long walk ...

I'm not a fan of running 15k miles between changes myself (while the oil may be stable that long, you're also circulating all the contaminants that your oil picks up much longer), but if you choose to do so, I'd use the matching oil filter. If M1 Extended Performance oil is what you choose, use the M1 Extended Performance oil filter that goes along with it. ...

Assuming that the Engine Oil Level is OK then you're gauge readings should resemble the following. At idle, the gauge should be between 1.5 and 3 depending on how long the vehicle has been sitting and the temperature outside (there are some other things that factor in here. Just trying to not complicate things too much.) Accelerating / Driving, the gauge, ...

Oil in the coolant reservoir is usually a pretty bad sign! Are there signs of coolant in the oil as well (a creamy mayonnaise-like substance)? Either of those are signs of Head Gasket failure, which would eventually stop the engine from starting, but would normally give a lot of other signs first... You say it started off as an intermittant problem - is it ...

In response to your questions Why did my car always had 16mpg when I just bought it, when it's supposed to have been 21mpg city and 29mpg highway? I do use AC, but I don't idle. I drove highway, from NC to ON, and never got anywhere close to 29mpg. There is always a "settling in" period for a new car - it should tell you in the owners manual for ...

My best guesses: You're burning oil, and extra combustible material in the combustion chambers gives you more energy output with the same amount of gas going in (and thus better effective mileage, although you're not measuring the oil you burned). Having less oil in the engine means less parasitic loss from the oil pump and perhaps other moving parts that ...

Firstly, 15km is enough to get the engine warmed up. It isn't as good as a regular blast to fully burn off deposits through the exhaust but it will get rid of condensation, so will help your exhaust system last longer. I think although you say you understood the answer in your link, I don't think you have. While looking for creamy residue on the oil cap is ...

Burning oil can cause fouled spark plugs, which can eventually lead to misfires. Burning oil could also potentially lead to valve issues if enough oil builds up. I'd imagine exhaust valves would be most susceptible. Your owner's manual may list an "acceptable" level of oil consumption, which could help you gauge how bad your condition is relative to what ...

Does the car have a turbocharger? If so, the seals in that could have gone, which would result in oil leaking into the exhaust. I'm assuming that photo is taken from underneath the car looking up? In which case the oil could have leaked from somewhere further up and run down onto the exhaust joint we can see. Does the smoke come out of the exhaust at the ...

It's easier just to buy the filter adapter kit for $50 that way you don't have to tap a return line either. That's what I did. But if your cheap sometimes engines have an extra oil feed bung down on the lower part of the engine block near where the oil pump would be just above the oil pan. Don't know if your jeep has one but worth a quick snoop.

I'm no expert on the subject so I'd take this with a grain of salt, but here's the thing with oil. The common belief is that when your oil starts to go darker then it's time for a change, but that isn't exactly true, as it actually means that the oil has been doing its secondary job of removing particles and dirt from the combustion chamber and suspended it ...

Oil in the coolant or vice versa is usually a sign of a failed head gasket and/or a cracked/warped head. Other symptoms include white exhaust (when not caused by low temperatures, obviously), exhaust gas in the coolant (causing bubbling in the coolant or "burping" of coolant into the expansion tank), and a high/fluctuating temperature gauge. The usual ...

Stainless steel changes colors from silver to gold to purple as it is exposed to heat. The picture isn't clear enough for me to confirm that is what has happened here, but it would explain the uneven coloring pattern. It will not change the performance of the dipstick or your engine. Edit: I see that the above answer was accepted, so I thought I'd add a ...

It sounds like you are getting drain back. When your engine sits without running for a period of time, most all of the oil in the oil passages drains back into the crank case. When you restart your engine, the oil has to be brought from the pan back up into the oil passages, then you see your oil pressure raise. Since I don't know which year your BMW is, I ...

All engines retain a small amount of residual oil even if you let the sump drain for awhile. If you do not change the oil filter then it will also be storing some oil in it. For diesel engines, particularly, it is advisable to change the oil filter each time you change the oil. Don’t be surprised if you change the lubricating oil in your diesel, run the ...
