Oil dipstick tube leaking

Oil dipstick tube leaking
I initially had some trouble figuring out where the hole was that the dipstick tube went in after my LT header install. Well, since then I've found the hole (at least I think so) but my car has been leaking from that area since last week (when I did the header install).
The dipstick tube still has the rubber o-ring, and I'm pushing the tube as far into the hole as it will go and then bolting it up. The tube remains firmly placed into the hole, yet it still leaks.
Just to be clear, is the circled area in the below pic the correct place for the dipstick tube to be inserted?
If so, does anyone know what might be causing the problems I've described, and what possible remedies might there be? I was thinking of getting a bigger/thicker rubber o-ring but I have no idea where to buy o-rings from.

O-ring
You should stick with a stock one. I may be wrong someone else with more experience may correct me but I had to pull mine when I installed my headers. The tube came out without the O-ring which leads me to believe there is a groove inside for it to fit in. I just slid my tube back in and never experienced any leaks. If yours is stuck on the tube it may not be seating in the correct place.

The o-ring should be on the tube. Check the o-ring for cuts. There is no oversize o-ring. Is this the original tube that you removed before the header installation?

It's a replacement tube that came with the headers.
I didn't check the old tube to see if the o-ring was on it. It's a definite possibility that the o-ring is still in the hole. I'm going to take it out, take the o-ring off, put it back in and see what happens.
I also just bought a big box of a bunch of different sized o-rings. I might o-ring it death to get it secured if the above fails.

I just realized there is another hole. I had to do a lot of bending to get this thing to fit in the hole it's in now. (the hole in the picture of my first post)
Is the hole in the above picture the right one?
Or is it the circled hole in this picture?

There are no holes in that area ,other than where the dip stick goes.
It is the hole in your first circled picture. It's on line with the end of the starter.
If you still have your original dip stick tube, it bolts to a hole in your engine block, right above the third exhaust manifold bolt from the very front of the engine.

I believe the oil level sensor is in that area as well. Check to see that it isn't leaking.
Are you running the original PVC system and did you touch the AIR tubes when you installed the headers?

Oil level sensor...where exactly is it and what does it look like? I've got a 'oil can' indicator on my HUD, so there may be a problem with the sensor. (the car isn't low on oil)
The headers don't have provisions for AIR so right now the hoses are just hanging out in the engine compartment, doing nothing.
Since I don't know what a PVC system is I'm guessing I didn't change it out.

your problem is now fixed
13mm bolt is in the LHS head holding the AIR tube in place, intake needs to come off the tube to remove; del code from PCM also

The accumulating pool of oil on my garage floor is. I wish there was a button for oil leakage.

I think it's leaking from the dip stick tube's hole, overflowing on that portion of the oil pan and finally dripping off on the lowest parts of the pan (those 2 bolts).
I've tried putting the tube in with no o-ring, assuming the original o-ring is stuck in the hole. I tried putting bunches of o-rings on the tube. I tried it with the 1 original o-ring. No matter how I do it there's still oil leaking.

1. ck oil with original dipstick AND tube
2. compare original tube to new tube
3. NOTE!!!! the tube AND the dipstick are BOTH different from early to 2001 and later
4. Get that original o-ring out of the block
5. Use a systematic approach and go back to first steps to troubleshoot
6. did it leak before the LT install?
that is all

I've got everything back together so I can drive it tomorrow. I have looked it over, however, and noticed no damage. It's only about a week old and has probably seen 100 miles.
