Got a great deal on a Flexible oil dip stick, unfortunately it is roughly a 7/16" OD tube and my block (2005 4.8 from a Express 2500 van) requires roughly a 3/8" diameter tube.

I have flipped the truck manifold and was planning to bolt the support bracket for the handle to a tab on the exhaust manifold.

Anybody got a link to a oil dip stick (flexible) that will work for my block?

 

How about brazing/welding a short piece of 3/8" tubing to the 7/8" ? That is IF the dipstick will still fit thru the 3/8"...….

 

I think the stick will fit, I have the stock dip stick and can cut the end off. Wondering if an epoxy would work here too.

Is the dip stick I have for an oil pan access hole?

 

Thanks for the idea G!

This is what I landed with.

I cut about 1" past the o-ring and collar off the orig tube

I was able to remove the tube from the coupling on the new stick
Then I drilled out the coupling so that I could press the old tube into the coupling

Before I pressed the old tube in a wiped it down with a little JB Weld

** No way I needed JB here as the press fit was tight but I had it laying around and never use it so why not.

Quick test fit has the stick hitting the oil so it is long enough. Just need to weld a mounting tab to the exhaust mani and I'll have myself a locking flexible dip stick that is totally out of the way.

 

Good to hear, man! Good ol' JBWeld…. better to use it and not need it, than to need it...…….. well you know the rest...lol
