C2 1967 w/Power Brakes Dip Stick Tube Angle

[Jimmy B.]

Since my old tube had been chopped off about 3 inches I ordered a new tube and installed same. It appears I am having difficulty getting my dip stick into the tube (I brought the tube straight up the side of the exhaust manifold between the 2 casting nubs vertical to the hole in the block.

My car is an L79 with power brakes, so I guess what I am asking is: on power brake cars was the tube/dipstick canted forward somewhat or was all the dipsticks tubes at the same angle regardless of power brakes?

Lastly could someone send me a more definitive picture of exactly how this tube came out of the block and its position in regard to placement alongside the exhaust manifold.

Thanks.

The tube was the same for both J-50 and non-J-50 applications. As far as I know, it was roughly positioned by the "guides" on the exhaust manifold for either application. The tube that you should have used is GM #3865664. This is not the original tube used for your application but is a SERVICE tube that will work perfectly. The only difference between it and the original tube is that the original had a swaged down top section and this one does not. Otherwise, it's identical.

As far as the dipstick insertion problem, I can think of 2 possibilities:

1) Sometimes, when the tubes are inserted into the orifice in the block they will go in "crooked". It may not be readily apparent by looking at it, though. Usually, though, if this happens the tube will not be really tight in the hole and will eventually fall out. If this occurs, you must start over again with a new tube; you cannot reuse the existing tube. In addition, this problem will also often cause a dipstick insertion problem;

2) Are you sure that the engine has the LOWER dipstick tube in place? This tube acts as a guide for the dipstick. Without it, or if this tube is bent, you will have dipstick insertion difficulty.
