Sorry dig, thanks for the move. beers on me.
Silly question, does the motor have the right type and quantity of oil? Is the oil clean and the filter new?
maybe 500 miles past optimum.

Change the oil and filter, using the correct oil (look it up if unsure).
Start there, see how it goes.
I have a feeling its the headgasket for some reason.
Is it a petrol or diesel? Do you have water on the dipstick? There are non-invasive ways of checking for a blown headgasket - a device with some chemical in it that changes colour in the presence of (I think) carbon-monoxide.... goes on where the radiator cap goes. A compression test may be handy, too. Does the car drive otherwise normally (power, etc.) ?
It gets hung around 3k rpm for a few seconds if I have to get on it. Thats about it, I am going to take it to the shop and have them hook it up.
hey man, was it a bad oil pressure sensor? Very unusual for your particular vehicle to have oil pressure issues. Unless you did some damage. Very remote chance of a defect but that is possible. Also change the oil filter, another possibility is the oil pressure regulator spring or a bad bypass in the filter. Let us know what you find out.
On another note today was a historic day at the shop. I wished I had a camera. A guy drove up in an 85 Yugo, it was yellow and black. In absolutely perfect condition. I swear it was mint, showroom. The man was in his 80's and just moved here from Alabama. He said he bought it for his wife but soon after she became ill. He kept it in his garage until a few years ago. Damn piece of **** was tight.
Audi 2.0 turbo. I hit the gas, getting on the freeway or some such thing, and then when I get up to speed and lift, there's a whirring noise. Like something is still spinning or, actually it sounds like it's unspooling.
Runs fine, still fast and all, just wondering what the racket is.
Ouch, it's a turbo! Open the hood and get someone to rev the engine, listen for the sound and where it comes from. Could be a belt pulley hopefully.
i have a 1987 nissan stanza, and the brake light on my dash keeps coming on, and from the manual, it says if that comes on I need to add break fluid, which I did. Could it be possibly something else that is keeping this light on all the time? (only when the key is in the ignition and the car is running)
is this something that I should worry about?
The sensor is probably sticking. I can't remember off hand if it is in the reservoir or a pressure sensor. Could you have other problems like leaking wheel cylinders, master cylinder or calipers? Low brake fluid is an indicator of two things, pad/shoe wear or a leak in the system. brakes do not "use" up fluid. I would do some more checking to see why the fluid was low, if there is air in the system and it uses a pressure sensor that will make the light come on. If it has a level sensor at the master cylinder, try tapping on it lightly. Main thing, check your brakes and see why the fluid was low.
alright, I will take a look at them this weekend and see if I can diagnose the problem.
thanks for the help!
Turbo bypass valve. That's the problem with my Audi 2.0 turbo. Thanks for your help.
DISCLAIMER: I know nothing about cars
So I've been in the habit lately of shifting into Neutral when going down steep hills or when I just want to coast to a slower speed while going down a hill, stuff like that. Anyways, I for some reason am thinking that I am somehow improving my 2005 Nissan Pathfinder's 15 MPG city 22 MPG highway gas mileage by doing this. Am I? Am I actually doing the reverse and wasting gas by doing so, or is the improvement in mileage so small that it's not worth doing anyways?
You're not saving any gas. Or any worth noticing.
Also, shifting to N while coasting down a hill, if you brake, will actually put more wear on your brakes, because you're not getting the braking force that the engine provides while in gear. And it's also going to be more dangerous should you need to make any maneuvers. I have heard that coasting in neutral is actually illegal but I'm not sure. Either way, I wouldn't bother doing it.
