Does anyone know what size is the weird bolt under the pushrods. It's the one thats like a big allen head bolt (I think it's called an XZN or torquehead). I think it threads into the oilways.

Full Version: Weird bolt under the pushrods
It is a secondary oil pressure relief valve. It dumps directly back into the oil pan.
Try using a 3/8" socket extension.

It's a metric 12 point head, size is M14. I actually bought the right tool for it a few years back. That special bolt holds in one of the oil pressure relief pistons and spring.
Not pressure relief.
Pressure control.
Pressure control.
