For the third time in six weeks I`ve opened the hood and found the dipstick has popped up as far as the hood will let it. Why?! Is there too much pressure? Too much vibration of some kind? A defective dipstick? (I drive a 2005 GT.)

That's a first... Does it feel snug when you push it in?

^LOL!


Well, seriously, have you tried taking the dipstick entirely out and putting it back in? Maybe it's in crooked.

Hmmm... Guess my post could be interpreted in a number of ways.

Yes dear, it feels snug... The first time I noticed it was after the dealer did the oil change. Then about two weeks ago I checked the oil and once again it was out. I actually took the dipstick out, tried to turn it around - thinking it was bound up. Then today - same problem. I don`t know... I love this car but I think I need a priest to exorcise it. With all the goofy problems I`ve had, there has to be an evil spirit somewhere.

Have you started your engine with the hood open to see if it is vibrating or maybe missing or something?

It probably won't pop out until you put your face right over it.

That'd happen to me anyway.

Never heard of that problem, I know a friend of mine hit such a nice size pot hole with his chrysler hit the under carriage hard, (most likel the oil pan) and popped his auto tranny stick out. Beside this, never hear of it on any car.

At first, it always does, but it loosens up after a bit...

Oh wait... check the plastic top of the dipstick to see if it's not the right size to hold the dipstick in place. FNG on the assembly line maybe?

If I ever start an employment agency, I will call it "FNG Temporary Services".

OK, this is a total WAG, but sounds like too much pressure - PCV valve or tubes can clog (or freeze if moisture is present) and pop the dipstick out.

The PVC system pulls fumes out of the crankcase. I dont think it bleeds off any pressure. I dont think that should be pressurized anyway. I think its MIGHT to be
1. Too much oil in the crankcase...
2. Bent dipstick. Depending on which way you put it in, it could be letting the crank wack it and push it up. Look at the tip and see if there are any scuff or nicks out of it.
good luck~!

I had it happen to me on my 06. Mine was probably because I had painted the dipstick handle including the part that goes into the tube. I removed the paint at the end of the handle, pushed it in hard and no problem since. Might want to be sure nothing has built up on the plastic part that goes in the tube. Also, make sure the O ring that is in this area is still there.

I discovered the dipstick up when the emissions light on the dash came on. It hasn't came on again. Is it possible for emissions light came on because the dipstick was up?

Well, that's not quite right. Small aircraft engines, which have oil breather tubes instead of a PCV system, usually have a "whistle hole" cut in the tube to keep the crankcase from overpressurizing if the breather tube should freeze at altitude. The pressure cannot blow the dipstick out of a plane because the dipsticks screw in. The crankcase can build up enough pressure to blow an engine seal. Here is a quote from a "Plane and Pilot" article ("Winter Flying", Dec 2006) on this issue:

"Make absolutely certain that your engine oil breather line has a “whistle slot” or supplemental breather hole, somewhere high inside the cowling. Your oil breather line opening will freeze over in cold weather. A supplemental breather hole will prevent pressurization of the engine case from pushing the nose seal out of your engine, and loss of engine oil."

Cars used to have breather tubes as well, until the PCV system recirculated the blowby back into the engine. A clogged PCV system will most certainly cause a pressure build up in the crankcase, pushing the dipstick out. If you could manage to secure the distick and keep it from popping out, the next weakest component could blow; in the case of a small aircraft engine, that's the front seal.

While this may not be the cause of the dipstick popping out, it is easy to check the PCV valve and tubes to determine if they are blocked and eliminate a bad PCV system as the problem.

Jeez, Mines just the opposite. Tug o war to get the stick out.

Just a guess.
But i think we both can agree Refire looks s*xy!

My God, here we are- online talking about dipsticks... perhaps we should all step away from the computer for a while and see what else life has to offer...
