Tapping Oil/Water Ports on VVT Block
#22
You mean to tell me that the little banjo bolt that passes into the block, through the hardline, is a BSPT thread? I was in agreement thats where it attaches, but I don't know if they'd use a tapered bolt on something that was to be sealed with two crush washers. The hardline itself has a bspt port for the pressure sender.

She was such a fun dog... Brainless and emotionally shallow, but fun.

I've had to drill holes like that in cast iron and cast steel in the past, but it was in a full on milling machine. Its possible, but its peck-peck-peck-peck-peck-peck ad infinitum. Clearing a chip out of a hole that deep and that small a diameter with a bit that long is just asking for trouble. Not to mention trying to get chips out and coolant in at the same time. No thank you.
Now that coolant port... that may have some merit.
