What else can I help you with?
Why do car cylinders loose pressure?
because you run them to hard and it causes wear and tear. Specialy when you drive alot at high rpms it causes metal to metal.
Why high pressure on low side of ac?
There could be a number of reasons, and those could be narrowed down a bit if you had included the actual pressure it was running (along with the high side pressure), as well as the ambient air temperature during testing. Possible causes may include excessive refrigerant and/or oil, a low pressure switch failure which causes the compressor to run constantly, and blockage on the low side. Incorrect testing methods are also a possibility.
What if you add to much oil to ac system?
System pressure will run abnormally high, the AC system will vibrate, and you won't get proper cooling.
How do you tune up a fuel injection pump on a 2002 7.3L powerstrok?
There is no fuel injection pump the fuel pressure going to the injectors should be about 60 PSI then the injector does the rest. There is a high pressure oil pump which provides high pressure oil to the injectors however a switch monitors that and if it is low the engine will not crank or run.
Does a 2000 dodge caravan have a oil pressure circuit protection?
If you are asking if the engine will shut off when the sensor does not detect oil pressure, the answer is no. It will run without an oil pressure reading.
What does it mean if you changed the oil on a 1993 Jeep Wrangler and the pressure is 70 and there is a ticking noise?
70 is little high for the oil pressure. It sounds like their could be some blockage in the oil holes that run to the top of the engine. The ticking could be coming from the lifters or valves not getting enough oil.
How do you know if the oil pump is bad on a 2007 Dodge Durango?
You will need to run an oil pressure test with a pressure gauge.
What is the ideal oil pressure for a 1987 MKIII Toyota Supra?
Anything over 4.5psi at idle and 35psi at 3krpm is in specs... I run 5w30 and at hot idle, around 10psi and around 42psi at 3krpm.... The supra has a high volume/low pressure system... no need for high pressure as the oil system in these cars is VERY effective.
1996 thunderbird 3.8 why is the oil pressure high?
It is normal for the oil pressure to be high when the engine is first started and is cold. It should settle at around 40 psi once the engine reaches full operating temperature. If it does not, then change the oil and filter and make sure you are using the correct weight oil, which is more than likely 5w30. Use a good oil filter such as Purolator, Wix, or Motorcraft in your Ford. Make sure to use the correct size filter. If none of this helps, then have an oil pressure test run, as your oil pressure gage may be wrong.
Does the jeep 2011 have an indicator light that there is no oil if it has run out?
There is a low oil pressure light.
Where does the oil pressure line run to underneath the dash of a 1977 trans am?
It runs from the oil pressure gauge to the sending unit on the engine.
What causes zero oil pressure reading in a 2003 GMC Sierra FWD?
The gauge may have gone bad, the oil pressure sending unit may have gone bad, the oil pump may have quit. I suggest you find the oil pressure line coming off engine, put another oil pressure gauge on it and then just crank the engien to see if you get any oil pressure whatsoever. If you don't, then I would check the oil pressure sending unit next before I tore the oil pan off to examine the oil pump itself. Whatever you do, do not run the engine with zero oil pressure otherwise you will seize up the engine and that will cost big bucks to repair.
