That raised boss part does not look like a broken off dip stick. It's too uniform.

Have you bought a new dip stick to look at and compare with the old one yet?

 

Just ordered one yesterday. Should be here by the week end

 

 

New dipstick finally made it. The picture shows I am missing something.I am not sure if it is still in the block or in the pan. When I took wiggle the original tube the piece in the photo is what I got. I wasted $70 with the tool shown. It did not bring the remainder up. Then I tried a 5/16 low carbon zinc lag bolt. It turned in tight and apparently I put enough pressure by hand to bend it. Went to a stainless 5/16 lag and after diving it up with a bar and hammer still no tube. I am now wondering if I possibly pushed it through and into the pan with the first lag bolt. The pictures prior to this do not look like it is a straight through hole to the pan which makes me think something is still there. I need to drain the oil/ filter anyway. Maybe try camera through drain hole and try to look up? If it it there it probably will stay. Pulling the pan sounds like a disaster.
other options;
Get the whole tube in as far as possible.If I cant get the bracket on the tube inline with the bolt hole I can make a small adapter piece to bolt it tight and mark the dipstick lower to show full.

As much as I hate too cut, the new tube just below the bell. Everything should bolt up and dipstick would be accurate. Then seal around the flange with red high temp silicone? I would not think pressure would be a problem?

Sorry I have drug this on so long.. I new this truck would be a project when I bought it. Very thankful to have this board for advice!
