Dipstick O-Ring question

Doing my CCV swap I decided to replace the dipstick O-ring. Should it put the O-ring onto the tube of the dipstick and then insert into the engine, or should I put the O-ring into the hole in the engine and then insert the dipstick?

When I put it back together I just slid the O-ring onto the dipstick tube and put it all back together, however looking with a flashlight I can see the O-ring sitting right on top of the hole, when I removed the original it was down in the hole, so I'm doubting it will seal right.

Thoughts?

Been there done that. It is a little tricky. The O-ring needs to be pushed into the bore. If it's sitting on top, you will leak oil. What I did was to first clean the bore/hole very well and made it as smooth as possible. Put the O-ring on the dipstick tube first up to the lip. Then, even though this is all surrounded by oil, lube it real well. I used an actual rubber lubricant but you can use something like petrolium jelly. Then just push down hard on the dipstick tube, wiggling and twisting while pushing. I used the hose bracket on the tube for more leverage. You should be able to walk the o-ring down into the bore where it belongs. Remember the O-ring is sealig via the inner and outer edges, not the top and bottom.
