Hey guys...thanks for all the replies and info.   Took the AMX to the local Cars/Coffee event a couple weeks ago, put a half quart of oil in it prior, just to be safe.  Car ran flawless.
My buddy and his Dad were there with their AMX and Javelin, snapped a crappy piture of the three cars together.
He had a spare dipstick tube bracket in new cond and gave it to me, ya meet good people driving AMX's!
I have ordered the Bultear tube and dipstick and plan to install it soon so I can check oil level and not worry about blowing the motor due to no oil.
I'll update the thread once it's in.  Thanks

May need to mark a new line on dipstick a 1/4 inch above full. I think I will do what someone here suggested cut it in two and install a compression fitting making sure that 1/4 inch longer adjustment. Than it can be disconnected if headers need to be changed or put on after the headers. Not sure who had done that with theirs. Maybe it could be reposted again. Thanks Larry


I wouldn't do anything to the stick before I took a reading off it after an oil change.  If the marks are off with 5 fresh quarts (or whatever your preference), you could always just make new marks on the backside of the stick.  The depth of the tube isn't important, just having an accurate mark on the stick is.

This may help those looking for dip stick tube. Yes broke my tube off trying to remove it to put headers on My SC Rambler so I could build the exhaust system. Looking at Summit web site they had a tube for a 401 for 5.99 so I thought what the heck give it a try. Well just received my new starter and dip stick tube today. Since motor is still in car not sure it the bottom end is correct. But the top end is a perfect match. Here is the part number OMX-1742402.
By the way is it possible with and easy out to remove the broken off dip stick from the top. Still working on front Suspension then rear end before motor comes out.

There are some pics here that give you a good view of where the dipstick tube is in relation to the block:

Also, I have a stick from a 73 CJ5 and a tube that isnt best shape but I have no need for it.  If that is useful to you PM me.  Yours for shipping.

The AMC dipsticks have a rubber cup that fits snugly over the end of the tube.  Seems like that rubber skirt is important to maintaining crankcase vacuum amd not sucking dirt into the engine.

If using a stubby shaft in a broken off stick I.dont think that rubber skirt will have anything to seal on. Probably noy a big deal but something to consider.

With the Buick stick you still need a tube in the block to guide the stick to the right spot though, correct? So if you had a dipstick tube that was broken off at the block the Buick one might be a quick solution?
Or do you use it with no tube at all?

This seems interesting. To get my headers out I have to pull the tube out first, there's no other way. Mine comes out easy now, but still I'd rather not jack with it at all.

Replacement Dipstick Tubes must be checked for correct size OD of the swagged friction bumps.
0.334 inch OD is the correct size of the 2 friction bumps on the dipstick tube that go in the block
per the notes I have saved, best way is to somehow re-swage, but some sand or file down OD,
some even enlarge the hole in the block.

iirc I installed a new dipstick and tube after the motor was in the car and the headers installed.

Skuttlebutt is with an AMC, run 1/2 to 1 Quart Oil overfilled to avoid pumping Pan Dry
if any "spirited" driving is on the itinerary, since drain-back off the heads etc back to pan can be slow.

When I had a broken one for awhile, I had the top of the Dipstick Tube with the Stick in it in the car,
and a bolt in the other broke off half still in the block, would reach, crawl, etc,
remove bolt and put broken half and stick down in block and check oil !  Ha ! 

Wonder what rear end gears are in that car ?  Some gears might make it quicker.
Does it have a stall converter?  Is it still the Borg Warner Automatic?
Here's a curiosity that would be nice to know, what are the Front and Rear U-Joint Angles?
Believe it or not, stock AMC set-up is Trans and Pinion both angled DOWN by the same degree, iirc.
Found my '69 Pinion required shimmed down with 4 deg Leaf Spring Shims to get it right,
point being, you saying you'd hope it would be a little faster / quicker... looking to help that.
Wonder what "tune" is on it, what Advance Curve...
What's the induction set-up ?Saw the show last year, but forget.

Some Dipstick Info posted in a thread here:


Someone posted here and image from an orig AMC source U-Joint Angle Info:

Guessing this is the part you are suggesting.

Does the header need to be pulled?  I'm not currently with the car.

Thanks for all the replies, guys.
