Yeah, I didn't even notice there was a discrepancy in the threading. I also just got the big kit of copper washers from HF for $5. It's got a size that works for both upper and lower banjo bolts. 2x washers for both bolts & you should be GTG.

The block is tapped BSPP, not BSPT.

Just double-checking... I also was unable to salvage the cam and crank angle plugs from my donor VVT engine and am wiring new plugs from scratch, and want to verify the pin order for both. The above post indicates the order (facing the sensor receptacle) from left to right is GRND / SIG / +12V. The 2005 wiring diagram (snippet below) show that the pin order is the same for both cam and crank sensors but the GRND and +12V pins seem to be reversed vs. the post above. Or perhaps I'm reading the diagram backwards. Can someone verify?

crap, my attachments didn't work as expected above. Below is the snippet from the 2005 wiring diagram. If I'm reading it correctly the GRND is on the left side in the diagram, but it would be on the right if facing the sensor. Post 402 shows a picture of the CAM sensor with GRND labeled on the left side. Is post 402 correct and I'm reading the diagram wrong?

Are these the pigtails Trackspeed sells? There aren't any photos on the page, just curious if this is what it looks like
