Fuel and Engines

If the difference between the high and low reading is within 10%, it is withing normal specification. If more than 10%, try squirting oil into the low cylinder and retest, if compression comes up , this indicates a bad ring, if not indicates problem is a bad valve.

Then that car has a neglected engine that will not last very long and I would not want that vehicle at any price.

hmm hard to answer this one, need more information. car either has a carburettor, a fuel injected throttle body, fuel injection. or electronic fuel injection.these systems are all different so it does make a difference on the answer. so we need to know which system your car has. is a 1994 Astro Van

12 mpg city 17mpg hwy you can average 15-16 if it is running perfectly, with a very lite foot. With a heavy foot, trailer towing, or excessive idle time expect 8-10mpg

it means starting of diesel engine

266 is the Net Horsepower Rating of the 'M' or 'Q' code 1972 351 Cleveland engine. The 'R' code engine was rated at 275 net HP in 1972.

The timing may be too far advanced, check against manufacturer's recommendation.

Any car will stall going around corners with only about 1 gallon of gas left in the tank (15-20 miles). A car should never be driven that low anyway as most modern cars have in the gas tank electric fuel pumps. The gas is actually used as a coolant for the fuel pump and if the car is driven too often down to the dregs of the fuel tank the fuel pump will prematurely fail due to overheating. It's a bear to replace the in tank fuel pumps on most cars. Also, it's not good for your gas mileage either to run the tank dry on a regular basis. Most fuel gauges are not all that accurate so when the gas gauge comes just to the "E" there should be about 2-3 gallons of gas left and you shouldn't push it beyond that. You should actually not drive past a quarter tank if at all possible. If you want to get a rough idea of how your fuel gauge is calibrated on a new or new to you car, fill the car completely up with gas. If the gauge reads much over the "F" (such as up to a quarter space on the gauge if it were marked past "F") you will most likely run out of gas right when the gauge hits "E". If the tank is completely full and stops at "F" without going past, you will usually have a small buffer at "E" before you completely run out of gas.

Chemical fumes are lung irritants. If the person moves to clean air quickly, the risk is minimal unless the person has an acute or chronic lung illness. If the person experiences shortness of breath, they should be checked by a physician.

Unburnt fuel

4.8L is 4800cc

Yes

Dirty fuel filter

Depends on the engine make, but you almost always need a large 3-jaw gear puller. Look at your engine manual for specific instructions.

CC is the cubic centimeter capacity of an engine

cc is the distance between the top dead center ie) piston end in top most and the bottom dead center ie) piston at the bottom most. It is simply called as how much volume occupied by the piston which one stroke

It is the cubic centimeter measurement of engine displacement.

He is right! Running a warm engine under load uses far less fuel and causes far less wear than running a cold engine under load.

This is why fire engines and other emergency vehicles often use engine preheater systems that keep the engine coolant at operating temperature (or close to it).

Also, you will use far less fuel in your first few miles of driving. That will more than make up for the fuel used warming up the engine (provided you aren't warming the engine for hours!).

As the earlier poster explained, warming up your engine means you'll use less fuel in total. That means less pollution, not more.

Engine oil works best when warm up to operating temperature. Also a cool down period is also recommended. If you just got off the freeway, drive around slowly for about 10 minutes to bring engine temperature down. This even more critical you have (or have added) a turbocharger. The shaft bearing on the turbo mostly uses engine oil to survive the brtual exhaust temperatures during boost. If the engine is prematurely shutdown while the turbo housing is still hot, the oil can coke in the shaft bearings. This is why performance auto stores sell turbo timers. A turbo timer lets you remove you remove your key from the ignition and the engine will continue to run for a few minutes, so the oil pump can do its work to cool the turbocharger.

This is impossible. Electricity is the result of electrons flowing through a conductor while jet fuel is a refined liquid byproduct of oil. As for "pollutant carbon" plants would disagree.

Buy one of the "flush in a can" products and follow the directions exactly.

if you want to do a machine flush your dodge dealer should be able to help you out. it wont be cheap, expect to pay between $100 and $150 for the flush and an oil change.

Sounds like the electronic fuel pump which is located inside the gas tank. also make sure you service the fuel filter the helps prolong the life of the pump. You've probably got a fuel pump going out. Mine lasted about a year from the time I noticed it.

The Corvette wasn't made with a 327ci V8 in 1970. A 1970 Corvette with the 350ci ZQ4 V8 puts out 300hp and with the 350ci LT1 V8 puts out 370hp (these are gross horse power figures).
