I've read a lot of posts about the oil dip stick popping out of its place. I had this too.

For instance I thought I had a clogged PCV. But even with a new one the dipstick popped out.

So I made my own fix, hope this help you guys. I call the rubber finger. It basically hold the dipstick cap against the valve cover to create a resistance to pop out.

You will need a paper towel, a 2cm (half inch) vacuum tubing piece. Scissors.

1. take out the dipstick and clean it out with towel. Clean the 2 rubber o Rings.
Notice under the cap, there's a trapezoid hole.



2. Take your silicone tubing piece and cut a strip ALONG the height. Approximately 7mm wide





3. Put the string inside the stick cap hole. Push all the way in. You can use pliers for better grip. Trim the width if you have problem fitting it in.

you should have this



4. Leave about 7mm stick out and cut the excess. Test fit on the valve cover. Trim as
the lenght of the piece until it's offers a good resistance to a hand pull.



Enjoy.

So far mine hasn't popped out yet.

has anyone ever replaced the o-rings on the dipstick ?. The dipstick on my engine is actually overly tight, I have to give it a hard yank before it pops out, I think the o-rings hold it in pretty snug.

Nice - I just bent my dipstick rod about 4-5" from the top to the right, now it sits snug.

^^ Wouldn't that give you an inaccurate oil level reading?

6 years later, I find this thread. 5 minutes later, my dipstick issues are gone. If you're still around here to read this, thanks for the writeup!

Interesting trick. Easy fix. I like it.

My dipstick starting popping up last fall on dyno runs just as the engine approached redline. I was going to develop a spring to hold the dipstick down but I solved the issue with other methods.

I replaced the O-rings. The factory green O-rings seem to harden up and develop a darker deposit on them as they age, you can see it in the OP's picture. This causes them to lose grip. I put in some new O-rings that ended up being a bit smaller in size, but they grip better so it works. I also changed oil brand and viscosity, hopefully getting less blow-by now.

Nice trick listed above by the OP though.

I tried replacing the O-rings as well. Bought a harbor freight kit and it solves the issue for a little while. But I check my oil frequently and not having the exact right size O-ring means they end up getting trashed pretty quick. Got tired of constantly swapping the O-rings so I was looking to see if just the OEM O-rings could be bought, not the whole dipstick when I came across this thread. Simple and effective solution.

I have another solution

If your dipstick is popping out, it's likely due to too much pressure in the crankcase, a properly setup, vented catch can is the probably the best way to solve the problem.
