My engine is a November 1966 350. The engine was rebuilt years ago but never run so I pulled the oil pan off to check everything over and then just put the pan back on. I need to install a dipstick tube for the engine. I watched a Youtube video of a guy installing and sealing the oil dipstick tube. In his video, he showed a dipstick "guide tube" inside the oil pan in addition to the dipstick tube on the outside. Mine did not have a "guide tube". So, my question is what is the correct assembly for this engine? Is it supposed to have a "guide tube" and, if so, is that pressed in from the bottom or does it go through the tube hole from above?

Thanks....

You need both the inner and outer dip stick tube to do it correctly. I made an upper tube indtaller a half century ago as i built engines for a living .To make the install tool go to you junk wrenches drawer and find an open end wrench that fits real snug against the bung on the upper tube cut it off and then weld an old fuelpump push rod to it at a slight angle so you can tap it in with a smear of silicone. Works like a charm . Alex

The inner tube goes in just like the outer tube. No tools required to install the inner tube. You don't absolutely have to have it, but the outer tube will be loose if it's not used. The wrench trick works well to install. I put a small smear of RTV around it before installing.

Darn, I will have to pull the pan back off. The engine is on an engine stand so easy to pull the pan. I used one of the Felpro Permadry gaskets so I think I can reuse it.

Both lower and upper tube go in from the top . No need to remove pan. Ernie.

Great, thanks for the info on the install. Glad I don't have to pull the pan back off. Will order both tubes.

Some reading that will alert you to a problem with cheap tubes. Yes from the top for both tubes. Always nice to Google these kinds of questions to see what you find out there on other forums.

Any idea what the best one is to buy for correct fit?

Heartbeat city sells quality at a fair price. Used many of their parts very satisfied with quality. Ernie.

I looked there. They have the upper tube but their lower tube is 69 and above. Having trouble finding both for the 67.

I had to run to my local muscle car parts place to pickup my special order trunk divider panel. As it turned out, they had a dipstick set (dipstick, upper tube and lower tube) so I picked those up at the same time. I have the lower tube installed and ready to install the upper tube. For the 67 SS 350 does the tube curve straight up from the hole or do you turn it slightly towards the front of the engine?

Sounds like you have the solution in hand.

If anyone is wondering about how this looks inside the oil pan.

As far as the upper tube, you can orient it any direction that works best in your engine bay.

I have mine with the bend directed toward the front of the engine.

Thanks for the pics. My car is on a rotisserie right now so setting up the engine on a run stand. Since I am building to stock I was hoping someone could show how it is oriented in a stock 67 SS 350 engine bay.
