On my 95 olds acheiva 6 cylinder, I am leaking oil very badly. Could 2 quarts of oil leak out of this tiny oil pressure switch plug? Do I have to remove starter to replace this switch? How does one replace this switch?

I've seen pressure switches rust out and shoot a steady steam of oil out of them, so yes it could cause you to loose two quarts of oil. Book does not mention starter removal:
REMOVAL & INSTALLATION

  1. Disconnect the negative battery cable
  2. Raise and safely support the vehicle.
  3. Drain the engine oil.
  4. Disconnect the switch electrical lead and unscrew the switch. To install:
  5. Coat the first two or three threads with sealer. Install the switch and tighten until snug.
  6. Attach the electrical lead.
  7. Lower the vehicle.
  8. Connect the battery cable and fill the engine with oil.

Keeps running out of oil


Put the car on a hoist and look for an oil leak. Here are the common places to find a leak. 1) Valve cover gasket, can leak down on the backside of the engine. You should find the back of the engine wet with oil all the way up. 2) Leaking drain plug or oil filter. 3) Leaking oil pressure switch. 4) Leaking front or rear main seal around the crankshaft.
If the motor and underneath is dry and has no oil present, check the inside of the tailpipe. You may have a broken oil ring on one of the cylinders, or bad valve stem seals inside the top of the cylinder head. Be blessed.

I changed the oil sensor on my 1997 mercury villager van, and it is still leaking oil. The oil lite never has come on and I checked oil last night and it was one quart low. Could the gasket on the oil...


The oil is leaking from wherever you see oil on the engine. Sometimes there can be to much oil covering the engine and it needs to be degreased. A dye can also be added to the oil that will illuminate when a dye light is used to help track down a leak. If the oil pressure switch you removed wasn't wet with oil or leaking than it wasn't bad.

It could be anything from the valve cover gaskets, cam seals, front crank seal, oil pan gasket, rear main seal or head gaskets.

Oil and Coolant leak of about 11/2 quarts coolant - 1/2 quart oil per night Leak 1 (Coolant) Appears to be coming from the radiator bottom right corner. Leak 2 (oil) Appears to be coming from the engine...


The passenger right side of the car doesn't have any flanges for cooling system, if that's correct then your radiator has a leak or puncture.

The driver side of vehicle has both the in and out flanges for the radiator. Very common to see leak at the drain valve leaking (not closed tightly). In the same area would be bottom flange of radiator which the composite flange is degrading and causing the leak.

The middle part of the bottom engine compartment is where your oil/coolant cooler assembly just above the oil filter. A loose oil filter could be the cause 95% of the time and 5% would be a bad o-ring from the oil cooler to the oil filter flange.

What are some solutions for a 1994 Camaro Z28 Lt1 engine, that has hesitation when at lower speeds. Some sputtering happens also. Have tried the usual fuel injectors. Occasionally this problems smooths...


The rear seal of the intake manifold will leak but the sendinging unit for oil pressure is more likly. if it's just a light on switch just change it for general practice as their cheap and the distrubutor drive can leak but you need the swich removed to check this area as the valve covers leaking are the most common problem don'et overlook them as they leak in all kinds of ways. miles and or time tells me how bad a leak is you can let'er sit and the oil drain plug can leak a 1/2 quart but you don't even drive itand does it leak if it sits? can you look under thew car with it running and see it drip? a 1/2 quart leak is easy to find unless you drive real far in 3 days. Oil pressure sending unit ( bet-so)

Oil leak, 5 quarts in 75 miles. Somewhere to the rear of the filter, filter OK


Hello thundergod: My name is Roger and I will answer your question.Their is a oil pressure switch located to the rear of the oil filter. Should have a shield over the terminal. When this switch ruptures you will have a large oil leak. If you unplug the switch and start the engine you will see the switch leak. If you have a gauge it is called a sender unit. If you have a light on the dash it is called a pressure switch. Please rate the quality of this answer as this is how we know you received the right answer. Thank You for using FixYa.Roger

High oil consumption 2001silverado 4wd, 4 door 6.0


Every manufacturer has a guideline.  But a quart every 1,000 miles seems higher then necessary.  Try the easy steps first. 1.  Check the PCV valve if clogged will caused pressure in crankcase and oil burning. 2. Remove spark plugs and perform visual inspection.  IF electrode is covered in gook(technical terms, sorry), then oil is leaking into that cylinder.  Most likely cause would be faulty valve stem seals. 3. Worse case scenario, engine oil rings are leaking.  If all else is good.  Perform compression test of each cylinder recording measurement, then add two small squirt of engine oil into each cylinder as you perform a second round, complete both dry then wet compression test on each cylinder before proceeding.  IF any cylinder shows a more significant increase in compression then it would indicate that cylinder's oil rings are faulty.  This is a major repair.  Keep me posted
