I'm in the proces of finishing up my 1330 build and encountered some problems with the banjo bolt. The wrong banjobolt was fitted I think (previous owner just glued it in I guess) Threads seem chewed up in the block. I was looking for the right bolt but can't find it. So I looked at conversion kits, 2 fittings and a braided line. None of the sizes correspond with what I have measured.
- Banjobolt that came with the engine: Thread minor: 14.7mm, major: 15.6mm
- Hole in block: 16.2mm
- Oil filter housing fitting: housing side maj 13mm min 12.3mm
- Oil filter housing fitting: pipe side maj 15.7mm min 14.8mm
Oil filter housing: 12A2032 So I would think 1/4 pipe thread which is 13.7mm but that's not what I'm measuring?
Banjo bolt should be 11/16unf which is around 17.5mm but I have 5/8 I think? It's a post 1992 engine so it should be 11/16 both block and bolt. The hole in the block is 16.2mm so the threads that are completely gone? Should be around 15mm minor, right?
The more I look into this the less that makes sense.
At this point I'm thinking to buy a conversion kit, drill out the block, tap a bigger thread and buy an extra custom fitting? Or is this saveable with a helicoil?
