I have a 05 z71 and lately on cold start up's the oil pressure gauge and info center tell's me low oil pressure for 3-5 seconds then the pressure comes up but not all the way after about 8-10 miles it

Oil gets thicker overtime and the oil filter gets clogged up with debris between changes/ cold environments cause sluggish thicker oil which takes longer warm and to reach its ideal viscosity operating temperature.A change of oil and filter would improve oil pressure reading on startup.

No oil pressure on idle

Did you check the oil level in the engine?
Since the oil pressure sensor is only a on/off switch set to change states at around 15 PSI, it's possible your sensor is going bad and giving false indication. Be aware that the oil pressure reading on the gauge is only a number made up by the computer, so depending on the state of the sensor switch, the gauge will display either 40 - 50 PSI or 0 PSI.

I have a 99 Jeep Grand Cherokee 4.7 oil pressure reads 40 at idle and drops to 0 when given rpms. Pull pan screen was clean. Noticed oil sending unit was leaking, I replaced it. I still have the same...

I just had the same problem with a malfunctioning gauge with a very oily sending unit. I went to Oreilly's auto and got a replacement sending unit for $38 and put it in and got the same results you did. I would have 40 psi at idle and it would drop to zero and throw the check gauges light when giving it throttle. I found some posts online that stated to only use official mopar sending units in these vehicles so I gave that a try. Problem solved!!! I now have 45-50 psi at idle and it climbs slightly when under throttle. The sending unit from Chrysler is around $52.

Hi all, my 99 sub.350,300k,missfire #2

Have you checked the distr cap for cracks??

If plug is oily looking on brand new plug I would suspect worn rings, which would also explain the high PSI. (Motor job in the wind) Especially for 300K.

White smoke coming out exhaust

well if it is white smoke and smells a little fishy, that is anti-freeze burning up so your head gasket mostlikely needs to be replace. but if it is a blueish white smoke that is oil being burn and that mean that you need to change your oil. if you have been changing you oil normally and it is giving you that then that means your pistion rings are worren. if you don't want to replace them you could put a heavier oil in like if normally you use 10w-30 you could put in 20w-50 in and that should help. worren pistion rings allow excess oil to get into the pistion chamber and that is why it burns it up, This should also be noticed by you oil level dropping faster then normal too.

'92 GMC PU has low oil pressure

With that kind of maintenace pump and bearings should be ok,the oil pressure sending units get weak on these models I have replaced alot of these for this same condition.The check engine light reads its voltage from the sensor.

I have a 99 chevy suburban that won't cool past 60 degrees and when idling is at 70 degrees. I have replaced the a/c compressor, orfice tube,the accumilator,rear expension valve, and fan clutch. My low...

These numbers are a little high depsite the high ambient conditions.Amazingly enough ,automotive low side suction pressure will equal the degrees its putting out at the evaporator coil...for instance,70 psi low side pressure will produce about 70 degrees of cooling. At 300 psi on the high side(which is high) this is about as low as the suction pressure will need it to go lower.I would probably be concerned with the freon level as a slight overcharge could boost these numbers.Poor air flow through the condenser can also create a higher head pressure than desired.If possible,I would evacuate and re-charge the system with the correct amount of 134a refrigerant. Try to get those pressures lower...about 250/50 would be a decent pressure value in this ambient condition.Verify good airflow through the coils and pay close attention to any foreign debris like plastic grocery bags or wrappers covering the coils...Ive even seen these make their way between the small gap between the condenser and radiator so use a light and inspect carefully for this.Air flow through that condenser coil is vital and any deficit there will create high head pressure which obviously causes high suction pressures....good luck

bout the oil pressure gauge its normal to go up but not to high coz u might overheat, try checking the cylinderhead gasket if there is pressure coming out, replace the gasket if needed

99 chevy suburban sevice engine soon light is on.

While the CEL is on you need to take it to an autoparts store and have the code read to know what is exactly going on. Just cuzz it seems to be running fine does not mean there isn't something wrong.
