SOURCE: buick regal oil cap

a6b6ca9.jpg A 90 Buick Regal Oil filler cap unscrews all the way out and does not "half-twist". It's just stuck. You may want to buy a replacement (about $4) before applying more force or tools to it, just in case it's brittle.

More than likely (and we will hope) it is the oil sending unit. In comparison it is a very cheap and quick fix to replacing the oil pump. Auto Zone has a pretty good componet location section that has tips for replacement if you cant find the sending unit or the oil pump. Try that first it may save you a lot of work.

The obvious answer would be to replace the filler cap. But I would look int why so much pressure is building under the valve cover. A Chilton/Haynes manual should give you some answers under the trouble-shooting heading.

Why on my1997tahoe when you remove the oil filler cap truck will stall and lots of suction

Well -doing that sort of takes out the PCV System
doesn't it

Unmetered air comes in the oil fill hole & gets drawn into
the intake & leans out the fuel mix

You also got PCV system issues with high vacuum

Bmw 318i oil leak

make sure that the filler cap seal is in place and not gone hard over time also has the rocker cover been off at some stage if it has check that the gasket has not moved the other thing to look out for is that the PCV (breather )valve is in good working order if it is damaged the sump compression will rise and push oil out

My 2000 chevy cavalier 2.2 4 cylnder has an high amount of back pressure in the crankcase ,if u pull of the oil filler cap with motor running it spits oil out and what seems like smoke ,it doesnt run hot...

check the PCV valve, If its plugged you'll get the same results, most back pressure in motors of any type is oil pump, defective check valve in the filter section , try this, remove the PVC valve and the oil cap at the same time and block the vacuum line to the PVC hose, this eliminates the PCV system, and see if that reduces the back pressure, the only other thing it could be is bad rings ( just a note, did you recently start using synthetic oil ?)

Oil is boiling in sump blowing burnt oil fumes out the filler cap

I doubt the oil is boiling in the sump or your engine would show signs of over heating. Change the PCV valve in the valve cover as it may be stuck closed causing internal pressure to build up and escape through the filler cap.

2000 Boxster overheating, blowing coolant out of coolant tank bleeder valve when overheating. This valve seems to stay in the raised position when engine warms up. Also after removing oil cap and covering...

Whatever you do, do not drive. I got the same problem about 4 hours ago and tried to get home. Half way, no oil pressure, overheat, silly noise from the engine.
Take your Boxster to a shop with a truck, you'll save money.

It may also damage the oil seals.

Oil leak through the distributor

why do you need to remove the filler cap when the car is running???
There is a seal around the distributor. Mark where the distributor is and remove it. Then replace the seal. Put it back together in the same location as before you removed it. It is also possible that your valve cover gasket is leaking and dripping on the distributor.
Cooling problem: Try washing the outside of the radiator where the cooling fins are. Spray it down with a really good degreaser and rinse it off. WARNING: Do NOT use high pressure because you will need a new rad after.

1984 ranger with 2.8 liter

If you have many miles on it you may have "Blow By" caused by oil and pressure escaping past the rings causing crank case pressure ... sometimes pushing out oil through the breather. With the engine hot and running ... remove the oil filler cap and see if it pops up ... like it's being pushed up from the inside.
