I bought a rebuilt '68 engine, dropped it into my '68 and am nearly ready to fire it up for the first time. I noticed that the dipstick tube only protrudes out of the block about 3/4". So I bought a dipstick and tube from Ames. The tube is 9 inces long, flared on one end and has slight curve to it. Does this tube work in conjuction with the tube that is already in the block? If so how? Please don't tell me that I have to drop the pan and replace the old tube with theis new one?

Thanks, Ryan

i just tore down a 68 350 (WK) and a 70 455 (YH) both had a two piece diptube, but both where rusted in so badly i had to work them for an hour from the bottom to get em out

I assume I have the two piece dipstick. One piece is in the block and the other piece is the 9” tube that I to press in??? Is the flared end supposed to be at the top? How does it press in?

try and find "yellowbird" here, i saw one of his relpy's with a link to his web page and there he has 2 downloads for assembly manual, and 68 service manual (huge files but awesome!!)

Your lower tube should stick out of the block about 2 inches. It has a rounded top edge so the upper tube slides in. Your upper tube depends on whether you have air conditioning or not. AC are longer. The top should be straight not flared. That's what originals look like. You can never tell what an aftermarket looks like. There are a lot of wrong tubes being sold. Year One has a good selection of correct tubes.

ls1chris , just an FYI, Yellowbird is a woman , very knowledgeable one, more so than most guys here so its easy to make the mistake from her posts ,but she is very much a lady , going by the name Vikki....

EEEKK!! hahaha!! well my apologies to vikki!! i have never encountered a woman before with so much insight or interest in her ride! way cool!!, i wish that would rub off on my wife (be really easy to get that COPO i found)

ls1chris, just let your wife know what a good investment it is, and that it's your retirement plan! (when she kicks you out... you can at least live in it for a while?) Lol...

Yes, Yellow Bird has been a great addition to our little community as of late! All who participate are an asset to this group, and some really have a lot to share! That's what makes this group so special!

Back to ryan's problem... Ryan, that has been one of the main issues I've had with my current motor.
Not sure if the lower tube was in the proper position, so in the end, I don't think my dip stick sits in the right position.

What I had to do was when I changed the oil, fill it up with the filter too, and run it for a while. once it sat for a day or so, I then checked the oil, and made my own mark to where the oil level was, (it was almost a quart off) and then I know when checking the oil.

I've not found any specifics or measurements to set the tube at from the start. But next time... Lol...

Hope this will help so you don't have to pull it back out?

Thanks, guys (and any other anonymous gals out there) This site has the greatest collection of information and advice I've ever seen, and I'm proud to be a member of the community.

Without this site I wouldn't know much at all about my 'bird, and once I start learning about something new I want to learn it all. Plus I have the technology to share it.

I just wish more of this would rub off on my husband!

Rub, Rub....
hope that worked...

Bjorn! You need to get out more...

No more rubbing other members... ah... strike that...

No more rubbing anyones Husb... ah... strike that...

Just don't go around rubbing anyone you don't know anymore Bjorn! Lol... (especially when the subject is Dipsticks!)

Brett! (hehehe)

Get out more? I just got back!

Thanks for the laugh!

Nice ride Yellowbird!

Ryan,

Someone out there is selling the dipstick combo for your car that's a little different than earlier described. I know ... it's what I ended up with (maybe Ames).

The upper dipstick tube inserts upward from inside the oilpan. The flared end remains in the oil pan. It's tapped into place. The lower tube is then inserted into the flared end. It's recommended that the two pieces be lightly tacked together with a welder.

The only problem with this setup is that there is a very slight gap visible around the uppper dipstick on the engine side. Not the prettiest, but can be easily filled so no one knows the difference.

I got sick of trying to get the correct tubes and finally opted for this combination.

When took my 69 400 block into be machined and was told that they would have to remove "brake" the old one. NO problem Ill get a new one. Well I tried three after market ones with no luck. Than I called the Pontiac dealer $18.00 and a week later I got the right one. Joe
