Why does your engine knock on your Chevy small block? Engines can make many different noises and people will describe them as knocks, pings, rattles or thumps. A true “knock” is caused by rod or main bearings hitting against the crankshaft. The general cause of that is either too much space between the bearing and crankshaft or insufficient oil pressure to maintain the distance between the bearing and crankshaft. Sometimes you can use a heavier grade oil so that the oil doesn’t leak out of the bearing space so quickly. If you’re currently using 5 W 15, go to a 10 W 30 or maybe even a 15 W If you can’t make the noise go away with that, either the bearings are too worn or it’s a different problem. If the engine has less than a couple hundred thousand miles, the only reason for bearings to go bad would be inadequate maintenance.
Bellows[ edit ] A pile of pressure capsules with corrugated diaphragms in an aneroid barograph In gauges intended to sense small pressures or pressure differences, or require that an absolute pressure be measured, the gear train and needle may be driven by an enclosed and sealed bellows chamber, called an aneroid, which means “without liquid”.
Early barometers used a column of liquid such as water or the liquid metal mercury suspended by a vacuum. This bellows configuration is used in aneroid barometers barometers with an indicating needle and dial card , altimeters , altitude recording barographs , and the altitude telemetry instruments used in weather balloon radiosondes. These devices use the sealed chamber as a reference pressure and are driven by the external pressure.
Other sensitive aircraft instruments such as air speed indicators and rate of climb indicators variometers have connections both to the internal part of the aneroid chamber and to an external enclosing chamber.

Why is Tire Pressure so Important? Here are three main reasons why your tire pressure is vastly important: You love your car, but gas prices are always fluctuating, especially following natural disasters. Nobody wants to wait for a tow truck to pick them up, especially for a problem that is so easily avoidable.
Smoother ride, happier you. Apart from that, there are a few actual reasons why having a smoother ride is better for your vehicle. Your tire pressure is directly related to your brakes. Slamming on the brake pedals without having proper pressure tire requires a longer distance to stop, and a looser grip on braking. How do I Check my Tire Pressure? That is, before you start your engine or drive your car at all. Your tires are most likely losing 1psi per month, on average from regular use, so checking them frequently is recommended.
Unscrew the knob, and apply the tip of your pressure checker to your tire pressure escape valve.
How to Install an Electrical Oil Pressure Gauge by Amelia Allonsy Electric oil pressure gauges are easy for a DIY-mechanic to install, whether replacing a faulty oil pressure gauge, or a custom, after-market look is desired. Oil pressure gauges are designed to inform the driver when the oil falls below a safe operating level, or when the oil pressure is too high. Driving a vehicle without an oil pressure gauge can lead to catastrophic engine failure.
Most oil pressure gauges come with mounting panels and the necessary installation hardware. The necessary hardware can be purchased from an auto parts dealer, if not included with the oil pressure gauge.

When jumpstarting a car you essentially give the dead battery just enough boost to start the engine and then rely on the alternator to charge the battery the rest of the way. When using a battery charger, you allow the battery to charge all the way before it will be used again. This should answer important questions such as what the voltage requirements are for charging your battery and whether or not you should remove it from the vehicle before charging.
There will be a manual with your battery charger that provides details for the appropriate use of the charger. Working in a well-ventilated area will help dissipate the hydrogen gas that batteries generate from the sulfuric acid within their cells. Also, make sure to keep any other volatile substances, such as gasoline, flammable materials, or ignition sources flames, cigarettes, matches, lighters away from the battery at all times.
Glasses, gloves, and other protective gear is a good precaution. Hydrogen released within the battery quickly converts to a gas and expands, this can cause the battery to explode if venting mechanisms fail. These accessories draw power from the battery and should be turned off before removing or charging the battery. Most batteries will be found either under the hood of the vehicle or in the trunk. It is also possible that your battery may be under the rear seat, and sometimes the battery can only be accessed from underneath the side of the car.
There are a few ways to tell which is which: Compare the diameters of the battery posts. For most batteries, the positive post is thicker than the negative post.
Plans I’ve never been a big user of any CAD program so hopefully these drawings will suffice. This is just to give you an overview of the design which was the second hardest part next to obtaining the materials. Designing a robust launching system took several tries and eventually I got to this one which seemed pretty solid. Each step I tried to include a drawing about what we are assembling to make it as easy as possible to follow.

Hook-up drawing indicates tubing slopes, position of instrument in reference to process tapping point, scope break between instrument vs piping. Hook-up drawing also gives information the requirement of bulk material for each installation. It also details its specification size, type and material and the quantity. There are two types of hook-up drawing: Process Hook-Up This hook-up drawing contains typical installations for instrument which connects to the process Pneumatic Hook-Up This hook-up drawing contains typical installations for instrument which requires instrument air such as control valve, actuated valve Reference drawing: A good designer can also read whether the instrument tapped in gas service or liquid service.
Installation detail specification will also specify items that should be utilized and factor that should be considered in one installation The purpose of Instrument Hook Up Drawing As stated earlier, information of the requirement of bulk material is stated for installation on each sheet hence the bulk material required for the whole drawings could be summarized and tabulated in a document named Material Take Off.
During project construction phase, this drawing is also referred as a guidance of how to install the instrument properly. Example of Instrument hook-up drawing.
The following instructions are for creating a MegaSquirt to Relay Board cable. It is for those who are creating their own harness. With both boxes mounted, measure the distance between them from DB connector to DB connector – this will be the length that you will cut the individual wires.
Jun 13, · My car did not come with the center gauges. I do have the gauges in the car though. Anyone have any ideas on how i can hook them up. I know i .
Report galtiero answered 3 years ago Just went through this with a sierra 5. Even though the truck had extremely low mileage and oil changes were routinely done sediment had built up in the engine. I would not count on it being a faulty sending unit. I had a long weekend and pulled the motor and tore it down and rebuilt it. I was shocked that this engine with only 79k on it looked worse than any engine I have ever torn down.
You have to love modern technology and lubricants. I did try the kerosene trick used it frequently in the 80’s when dealing with barn find type vehicles that had not been run in years it sis me no good, I also tried raising the motor just enough to drop the oil pan and clean the sediment out of the pan but neither worked because the block is higher in the engine. The only thing I did not try was to completely and I do mean completely fill the motor with K-1 and let it sit for a few days than drain and repeat.
I did this with some vehicles in the 70’s and 80’s that had extreme varnishing but I am not sure I would try that with a modern engine. Also keep in mind that every time you put a high detergent product in the engine you run the risk of having a large piece of scale dislodge and be to large and hardened to be broken down causing it to become an even worse blockage than you started with. If you want to keep the engine have it torn down and fixed right or it will nickel and dime you to death.
