Got a issue after the mechanics shoved my distributor back in didn't set it right,I've been fixing all their mistakes,i never paid them told them they never finished the job.

The next issue I'm having is the banjo bolt on the passenger side head doesn't wanna go in,there were times I'm trying n trying n it wanted to go but a no go. I even swapped bolts same thing.Just keeps slipping out.

I took the line off n tried screwing it in then it went great in the head,im confused hoping i don't have to remove the heads again.

Is there a different bolt I can use or does it have to be that banjo bolt bcuz I noticed the holes in the banjo bolt assuming it's for coolant to circulate

I have seen people convert that line to AN Fittings.

It is a steam pipe so a regular bolt won't work.

If the bolts go in without the pipe attached, I am going to go out on a limb, and say, you aren't getting it lined up perfectly straight.

I know it's very tight space, maybe your line got bent a little. Take your time you will get it.

-AN fittings are typically used for braided S/S lines with fuel, nitrous, oil, etc.:

While people seem to reference the threads in the heads as 1/4" NPT, Shoebox indicates:

"It's a special thread (1/4-18 NPSF) dryseal, straight pipe thread"

NPSM. National Pipe Straight Mechanical. I think that's what they are.

Don't think so.

The National Pipe Straight Mechnical (NPSM) female fitting has a straight thread and an inverted 30° seat.

The NPSF is a straight thread and uses the sealing washers to seal. The NPSM uses a chamfer for sealing.

The NPSF designation is right out of the parts book.

This is correct and is the reason the banjo bolts require a pair of washers to seal them. Also, a NPT threaded AN fitting will screw into the ports with a little effort and will seal just fine.

You can get them from the vendor of your choice. Hardware store? Probably not.
