Oil dipstick mystery
 

After any amount of driving, my oil dipstick has popped up from the check tube and is hanging sometimes an inch or two above the seated position. The last time it was out so far I could see the metal strip inside the tube. What gives? Does anyone elses do this?? Is my dipstick a jack-in-the-box? Im hoping this isnt from blow-by gasses from the cylinders :confused: Its only got 139K.

Mine does it too. I wrapped some teflon plumbing tape around the o-ring and it worked for a while but did it again after a couple of weeks. A new o-ring sounds like a good cure and cheap too. I got my power steering reservoir o-ring for 10¢.

It certainly is.:) The PCV needs replacing, to allow the case pressure to pass to the inlet.

What about when you have replaced the O-Ring and replaced the PCV valve and it continues to do it?:confused::(

No the ECU can't tell.

Yes mate, It can still happen, if the passages in the air box in front of the throttle bodies, are blocked with goo. This is the passages that connect the two cam cover breathers to the Ventilation valve.

If you look at where the two breather pipes enter the box, it looks like they just go straight in, but they both go into a small passage that connects through a restriction to the PCV valve.

These are where the engine flows the crank case pressure, under full throttle as the PCV valve is closed then.

I would pull the air box off and clean out the breather passages.

Usually just replacing the O-ring does the trick. It may not be pressure build up, but just vibration that moves it up. After getting a new O-ring, it should stop doing that. :)

I was just wondering about this today. This a regular Autozone part?

Re: Oil dipstick mystery
 

I would do the pcv anyhow. It can cause some weird ****.

Re: Oil dipstick mystery
 

the pvc or the o ring?

Re: Oil dipstick mystery
 

I would replace them both. You could start with the o-ring. :)

Re: Oil dipstick mystery
 

Even with a bad O ring the dipstick should not pop without internal pressure.

As per Harvey's #8 post. Treat the cause, not the symptom.

Do the PCV valve. Clean the gunked up passages. Replace the O ring.

No more problems.
