Rockers

[jmoore]

I'm in the middle of a head gasket change. I just got my heads back from the machine shop for the valve job and they look PURTY!

One question. I was looking at the rockers and noticed they are non-adjustable. Was there no provision to adjust them for wear over time? How does the engine then keep consistant lift on the valves?

Another question.

I have new head bolts. What are some of the techniques you guys have used to ensure you have the right torque? I've read you're supposed to torque to 15#, then turn 90* then another 90*. My machinist said there is a tool you can fit to your torque wrench that measures the 90* turn. I'm sure that will be very difficult with those back two bolts. What have you guys done?

The rockers are not adjustable due to the hydraulic lifters that are essentially self-adjusting.

Don't bother with the angle torque gauge. Torque to the initial torque. Use a paint pen andmake a mark from the top of the bolt to the halfway mark. Turn 90', then turn 90' and the mark will be pointing downward and you know you're done!

Thanks Paul! Will do.
