The fuel filter in my 94 Chrysler Town & Country is due for replacement. The Haynes manual I have says to jumper one of the injectors to ground and +, to dump the residual pressured fuel into one of the cylinders.

This doesn't sound right to me or my grandfather, so is this right? if not, how would I do it?

Disable fuel pump by pulling the appropriate fuse, then start the car and run it until it stalls. On the fuel rail there should be a little cap that you can remove to reveal a schroeder valve that you can press to let out the pressure from the fuel rail. Keep a shop rag there, you don't want fuel spraying around your engine bay.

At least, thats how it was on my 94 saturn when I did it. Yours may be similar, or completely different :iiam:

That worked! There was a lot of fuel left in the rail, and we panicked when it dripped off the rag ind inbetween the valve cover and intake plenum and started BOILING, but besides that and the stupid clamps, and the headache I have now from rolling around to get tools, it was pretty easy.

Thank you very much for the help.

New brake pads and rotors most likely. $100 at brakes plus if the rotors don't need to be replaced. More if they do.

Go get new brake pads ASAP. If you wait top long (quite likely it's already too late) your rotors are going to be hosed and it is going to cost A LOT more than a simple brake job.

New tire/spare tire questions:

If I have to get a new tire (because of a flat), and the rest of the tires have 80% tread left, will that be ok? What if the rest of the tires only have 50% or 20% tread left?

And I know that usually you'd want the tires on the drive wheels to be as similar as possible (e.g., on a FWD you'd put the 80% tires on the front and put the new one on the back), but what about with an AWD system?

Man, I'm posting a lot on here lately.

My shifter is starting to feel pretty loose, especially going into 5th/Reverse (2003 Cavalier 5 speed). It doesn't like to rebound too much from pushing it to the right and it wobbles when in gear. I think I remember someone mentioning that it could be a loose linkage somewhere. Where would I look to find this? If I jacked the car up and got underneath, would I see it, or would I need to disassemble something on the inside of the car? What would I be looking for in the first place?

The Mote in God's Eye

What is the difference between a big block and a small block engine? I'm reading Wikipedia and I feel like I'm missing something. A big block is:

"A big-block engine is a North American V8 in a family of engines which generally have greater than 5.9 L (360 cubic inches) of displacement; factory engine sizes reached a peak of 8.2 L (500 cubic inches) in Cadillac's 1970s range."

And a small block is:

"A small-block engine is a North American V8 in a family of engines which generally have less than 6 liters (360 in³) of displacement."

This is pretty straightforward. But then:

"There are Small-block and Big-block engines. These families differ in respect to the distance between cylinder bores, but not necessarily in displacement since the latter is defined by bore and stroke.

Whilst the big-blocks have been less commonly used in recent years, the small-block families have grown in displacement and have now reached a level that was reserved for big-blocks in previous years (up to 7 litres of displacement in a Corvette). Even though the technology has greatly changed, basic specifications have been the same for fifty years[1]."

OK, so you can have a 7 litre small block engine because the advance of engine technology allows you to build cylinders much closer together then you could in the 60s. But does that mean big block/small block is just an old marketing term, and all modern V8s (regardless of size)are small blocks? If the cylinder bore is the essential detail, could you have a 4L V8 big block? Could you describe the Mercedes 450SEL 6.9 as having a big block?

These are all unimportant questions, but I always wonder about then when I hear people talking about old engines from the 60s.

This guy just rear ended my 06 Elantra at about 5 mph. So far, the only damage seems to be a hole in the bumper's fiberglass where his license plate bolt/screw punctured it. Can body shops fill a hole like that? If they do, will it last the life of the car? Or should I make him get me a new bumper.

Okay, I'm a bit of a noob when it comes to cars, because I don't have my licence yet (though am taking lessons).

The stock CD player just crapped out in our 2002 Mitsubishi Magna (Series 2). I'm guessing it'll be cheaper to buy a new head unit than get it repaired. Not looking for anything fancy, or to upgrade the speakers or anything.

How easy is it to install a new stereo? I presume it'll just involve removing part of the dash surrounding it and undoing the brackets/cables. Analogous to installing a new hard drive I guess? I don't think I'll bother paying for installation unless you really recommend it. I have allen keys, screwdrivers etc and built my own computer, so I'm fairly confident I can do this myself.

We'll probably head over to JB Hifi later this afternoon to have a look at what they have in stock. Although I hate the sales people, they generally have decent mid-range stuff.

I've always been told to buy a minimum of two tires at a time. And to keep those two either together in the front or rear.

If you buy the stereo and all the needed adapters, it should just be plug-and-play. However, getting the dash off is a royal bitch. Go to Best Buy or Circuit City, buy your stuff there, and have them do a free installation. I know Best Buy has a policy that they will undo any installation for the life of the stereo, also. If you're just getting a cheap head unit, I think that's the easiest thing to do.

I'm in Australia, so we don't have Best Buy or Circuit City, but I know JB do do installations. If they'll do it for free or a decent price, and can do it today, I might as well take them up on the offer while I do my other shopping. My wife's out with the car at the moment, but I'll have a look at the dash before we go.

Big block/small block is generally used to differentiate between two engines by the same manufacturer, but they don't directly translate from Ford to Chevy to Dodge. The companies had two basic designs for a V8 engine, and to make one of a certain displacement they would choose the proper size and then design the cylinders into it. Small block engines were used for most engines under 6 liters, and above that big blocks were used because of the sheer need for space.

Modern engines do not really fall under these categories. A Ford 4.6 is neither a small nor big block because there is no easy comparison like there used to be. Only Chevrolet's engines are still classified like this, because the LS series of V8s has the same dimensions as their classic small block.

To answer the other questions, you could have a 4-liter big block, but it would be a pretty bad choice unless you were trying to build an indestructible utility engine. A Mercedes engine wouldn't be either one because Mercedes' designs weren't done in the same fashion.

Is it the "check oil" light? or just the "oil" light. Like the light with a little oil can on it? That doesn't mean check oil, it means the oil pressure is low.

The best case scenario is that it means the oil pressure sensor is bad, and allowing the oil light to come on at normal oil pressure, so get that checked out first. It's like a ten dollar part.

If that's not the problem, it means your oil pressure is actually too low during low RPM's... which means you've either got a clog like you said, a worn out oil pump, or a lot of engine wear. Either way, with low oil pressure it's just a matter of time before you knock a rod out. I'd get it checked out by a shop immediately.
Yeah it's the little oil can, the only oil light I have. My oil sensor is a $45 part, so I'm hoping to test it and my oil pressure as well before replacing anything. I have a compression testing kit, is there some way I can use that to test oil pressure and avoid having to buy a new kit? This will be a moot point in a week when I get paid, but I have to drive the car to and from work until then so I'd like to find out if there's a real problem that could be causing engine damage.

If you're just replacing oil that's leaked out, use the cheap stuff. It won't be in there long enough to really get you into any trouble.
Also, I assume a (base?) Taurus doesn't have a very performant engine that would require synthetic oil, but don't take my word for it.

I agree with the fact that the oil leaks but if I were to get the oil pan replaced, thus stopping the leak would it make a difference then? No the engine is only a 3.0 V6 but for it's age it runs well and with all the "special" oils out there for "high mileage engines" I was just wondering if any of them actually make a difference.

I replaced the power steering pump in my brother's girlfriend's 98 Buick Century Limited and when I topped off the reservoir and started the car the power steering worked fine. After turning the car off for a while we went back out to it and it didn't work anymore but I figured that there is air in the system because the steering fluid is foamy. Would air in the system cause the power steering to not work? I'm about to go over to her place and bleed the system but I'd like to know if anyone thinks it'll work.

You should have filled the reservoir to the top, cycled the steering wheel lock-to-lock a few times with the engine on, and checked level again. Chances are, the level went low. Hopefully, you didn't damage the new pump.

if you're sure it's not the belt, it's probably the bearings inside the pump. They can get worn out quickly if the belt is overtightened. Same goes for water pumps, alternators, a/c pumps, etc.

Unfortunately if the sensor isn't bad then you've been running your engine with low oil pressure (momentarily) and that could mean engine damage. No way to really tell until the bearings start knocking.

A compression tester can't be used to test your oil pressure. The only way I can think of to test oil pressure is to hook up a real oil pressure gage to the same spot as the sensor. I hope the sensor is just flaking out.

I was thinking it was the bearings because the belt is just fine, and hasn't been removed or adjusted (well, has a self tensioner) since I did the alternator last summer. Sure sounds like bearings. Guess I'll drive it till it seizes...
