Oil Dipstick Tubes For the 1968 400

Q: Oil Dipstick Tubes For the 1968 400

What is the correct tube for a 400?

A: After some research into the question of oil dip stick tubes for the 400 firebird I found that it has three tubes.

The first is in the oil pan, the block to baffle tube, a short curved piece about five inches long and copper in color. The second is about nine inches long and ever so slightly curved, which extends from the outside of the block to the third and final section. Lastly, the third tube runs up from the end second tube to where it itself ends, just above the rocker cover. The dip stick itself is inserted and held into the third tube, which has a small bracket that attaches to the front outside rocker cover bolt. The GM numbers for these are as follows: block to baffle #546281 9″ curved (GM calls it straight) #9795830 upper #480843

I was able to purchase all but the upper of these at my local pontiac dealer. That one they stocked, but were temporarily out of.
