Take them off the hood, then try inundating the nozzle in a mixture of CLR, or lime-away, and water. Let it rest for about five minutes or so. After that, run some pressured water through the nozzle with a garden hose. Then try reversing the direction of the current by shooting water through the other side. Hope this helps
If you have crankcase pressure in an engine, it's because your crankcase ventilation system has become clogged. There is a hose running from your valve cover to your air intake; this gets clogged up with oil. Pull it out, clean it in solvent, blow through the hose to make sure you can, and put the car back together.
Clogged fuel filter or the pump is defective even though it is running. It may be running but not pumping any fuel.
If fuel cannot get through the fuel filter, it will stop running.
It's a gauge which displays the measured pressure of oil running through the system. Pretty self explanatory.
There is no word beginning with b that refers to lines on a map running through places experiencing equal pressure. Those lines are called isobars, meaning lines of equal pressure. (iso means the same and bar is a unit of measure of pressure.)
Chandge the fuel filter first then try running some injector cleaner through it. If that doesn't work a mechanic will have to look at it.
If the low jets are always running but the hater never heats it could also be the pressure switch is either bad or clogged. The pressure switch senses whether there is water flow and will only allow the heating element to operate when there is suffcient water flow through the heater. I had to replace the heating element in mine when it wouldn't got above 80 degrees F (or so).
Lots of things. Bad plugs/wires, clogged air filter, clogged fuel filter, clogged fuel injectors, faulty fuel pressure regulator...Replace the plugs & wires, change the air and fuel filter, and run a bottle of GM Top Engine cleaner through it.
Check pipe size for hot water or if galvanized pipe used, pipe could be clogged inside with rust and scale.
Check the vacuum hose under the hood. May have a leak or have been disconnected. Also check - The blower - this includes its motor, fan and associated components/wiring. Next to check is the coil (this looks like a small radiator) through which the blower moves air is clogged. Check if the vents themselves are clogged.
If conditions in the crankcase have become so bad that the oil pickup screen is clogged, you have more of a problem than just a clogged screen. If someone has poured sawdust or other trash into the crankcase you MIGHT be able to pull the pan and clean the screen. If it's clogged for any other reason, you'll need to rebuild the engine.
Remove it and blow through to see if it is clogged. Rather than seeing if it is clogged just replace it to make sure.
