dipstick tube

The internal dipstick tube extension, that's inside of the crankcase: what keeps it from sliding out of the engine block? I'm trying to re-install mine, and it seems like it will just fall out.

Re: dipstick tube

It should be flanged at the top.

I'm suffering from memory loss - does the tube then drop into the block from the outside, with the flange staying seated at the top outside of the block? That would make sense, but I didn't think the dipstick tube would fit into it?

Re: dipstick tube

Once you got it in there, I use a Spark Plug Rubber End off an Ignition Wire and slip it over the Tube to Pan Joint. This will ensure no Oil Leaks out. You might have to slide the Rubber Collar on the tube first, if your tube has a top bracket ;o)

Re: dipstick tube

The block is counterbored approx. 3/4" for the internal tube and the outer tube is pressed into the block butting up against the internal tube. At least on a SB.

Re: dipstick tube

I know a lot of original SB chevy dipsticks and also aftermarket versions have a bracket that's typically welded or attached to the tube that goes into the block. The bracket then has a mounting location such as a header bolt or valve cover bolt that keeps it from ever sliding up. Not sure what was stock on 1st gens but that configuration is what I have on my original vette and my after-market ZZ383 in the Camaro.

I'm not talking about the external dipstick tube; I'm talking about the extension tube that's inside of the block/crankcase. It slides up into the block hole to meet the end of the external dipstick tube. The other end protrudes into the crankcase below the crankshaft and acts as a guide for the dipstick.

If someone has a picture of this, that would be great.

Yea, But it goes in from the top, I should have explained that in my post. The block is counterbored as I posted and the lower tube goes in first (from the top side of the engine deck), bottoming against the machined step, then the upper tube is pressed in.
Hope this Helps. Mike.

Re: dipstick tube

Here is a pic of it http://www.ecklers.com/product.asp?p...77&dept_id=153 As Mike said it goes in from the top and the dipstick tube goes in on top of it.

Re: dipstick tube

click! The light just came on! Thanks for the explanation - that makes sense now. I usually take digital pics when I'm getting ready to tear something down, but didn't this time. Cheers
