Blow-by (Bad engine rings)
why does oil come out of dipstick on a1996 12v commin
I'm not a mechanic / technician but I believe that a plugged PCV valve or hose will cause oil to blow through the engine oil dipstick
Typically its either worn or broken Piston compression rings.
It could be a clogged PVC valve.
Most cars have some blow by or compression in the oil pan from wear in the motor. This being the case there may a small amount of oil blown out of the dipstick tube.
To read the oil dipstick in the 1997 Ford F150, remove the dipstick from the oil reservoir. Wipe the dipstick clean and then place it back into the reservoir. Then, remove the dipstick again and look for the height of the oil on the stick. It should be in the "Full" range.
Pull out the dipstick, wipe it off, put the dipstick back in, pull it back out, and see where the oil level is in relation to the "Full" and "Add" lines.
It could be blow by, escaping exhaust gasses pushing past the cylinder rings creating excessive pressure in the crank case causing the dipstick to pop out to relieve said pressure. That or tiny elves.
A broken engine dipstick should not cause anything or have an effect on anything. A broken dipstick will make it impossible to check the engine oil and should be replaced as soon as possible.
if oil is blowing out dipstick hole, this indicates that the inside of engine and oil pan are pressurizing.check to make sure oil filler cap is venting and not clogged.if this is not the problem, the other cause is broken piston rings causing pressurization of engine
The 98 cavalier holds 4.25 quarts. of oil approximately. The missing dipstick can cause oil to blow out of the dipstick tube while driving.
