    Have you got any external gauge or anything you can use to confirm oil pressure? How hard to get a rocker cover off on that ?

Only way to know for sure would be to drop the oil pan and check the oil pump sump for debris clogging it, is there any Hollow Knocking noises ? or just top end rattling ? or No noise at all ?

    If pressure is present and then drops its evidence of a clgged pick assembly. but an external pressure gauge would confirm evidance of any oil pressure , The Association of engine rebuilders reccomends no less then 7psi per 1000 rpm as a rule for minumum pressure . good luck in the pursuit of oil pressure !!

SOURCE: oil pressure gauge goes to 0 when idled, but goes

You could try thicker oil or stop using synthetic or add some lucas oil treatment or change the oil. The sender could be bad too. A diag is in order because if there is no presure the engine will soon die.

Oil light comes on and is dinging.


The oil light has nothing to do will oil level, but rather oil PRESSURE. If the engine oil is full and there is no rattling or banging noises in the engine, chances are the oil pressure sending unit is bad. If noises accompany the light, then shut down the engine and troubleshooting the engines internal lubrication system.

Check gauges light 2001 dodge dakota atfer replacing power steering pump


The oil light is warning the driver the engine has no oil pressure. That could be due to the engine oil level being low, or because of a problem with the oil pump.
is it possible you unplugged or damaged the oil pressure switch on the engine ?

Oil light keeps coming on


1992 ford explorer with the oil light coming on, this can be due to a bad switch, this switch is called the oil pressure switch and is located near the oil filter area, this would be the cheapest way to go first and if the light still comes on then you will need to have a pressure gauge hooked to where the switch goes and the gauge will tell you if its really low on oil pressure and if it is then this may be due to worn engine bearings or weak oil pump, i will tell you i have not seen an explorer with low oil pressure just needing a oil pump, most of the time it is time for another engine. what =i have seen is alot of them with bad oil pressure switches that were making the oil light come on . hope this is helpful, good luck.

2001 F150 pressure gauge reads zero and light comes on when slowing down to 1st gear and stopped, sometimes light and gauge goes off and pressure returns, but fluctuates...also when gas applied and vehicle...


I assume you mean "Oil" pressure...This is the first sign of the main bearings getting to the point of needing replacement. The fact that the pressure goes up when you accelerate tells me that the oil pump is working. There is just too much bearing clearance for the oil pump to keep enough volume flowing at idle to maintain pressure. In short, it's time for an overhaul. It will be less expensive if you do it now than if you wait until you spin a bearing and destroy a crankshaft, or put a rod through the side of the engine block.

Wont idle or start without priming tbi


first check fuel pressure with a mechanical fuel gauge that attaches to fuel line schrader valve. around T.B.I. if no pressure with key on check fuel pump relay for correct operation, and also the oil pressure switch has the fuel circuit to it so possible oil pressure switch also. fuel pump has a check valve to keep fuel from going back to tank, so when u turn key on fuel pressure should go up within 1-2 seconds on gauge. if fuel pressure goes down quickly, possible bad fuel check valve, change fuel pump and fuel pump check valve (located right above fuel pump inside tank)

Gauges work fine when engine's started, then oil gauge falls below zero and warning light comes on saying "Check gauges," so I check the oil and transmission fluid levels and these are fine but...


start by checking the ground strap to the engine, and engine to body. The oil pressure sender unit may be bad. You may have to hook up an oil pressure gauge to the oil pressure sender port to verify proper oil pressure. Senders are cheap- I would just replace it and go from there.

My 2002 grand cherekee check gauge lights keeps coming on and the oil gauge would drop when I slow down or is at a stop. Please advise


This could be a faulty oil pump. or more commonly a bad oil pressure sensor you can call. If its the pump i recomend you have it fixed as soon as possible. The check gauges lights up because the oil pressure isnt as much as required. But common problem is the sensor replace the sensor and the engine oil along with a filter hope this solves your problem.

Oil gauge drops all the way down and check gauge light comes on


Could be the oil pressure sender has gone bad or worse case scenario the oil pump has worn out. Check the oil presssure sender first, if it is leaking around it then that is the cause, if not then you may be looking at an oil pump. Just had a 03 ram 2500 doing the same thing and it was the sender, but that was a hemi and it had 230000 miles and a month later had to replace the oil pump for same issue.

When i come into a complete stop the oil gauge goes down.


If it's your oil pressure gauge, that is usually normal. The pressure will rise and fall with the RPM's of the engine, since the oil pump runs off of the engine itself.

Do you have a CEL coming on when it does that? If so, got to Autozone or Advanced, and get the codes from it, and myself or someone on here can help you fix it.
