How to open up rocker arm oil passages.

Duggie said

* The wire I used would not go past the hole opening. Too large maybe? What direction is the passage supposed to go when trying to force the wire past the hole? Can the wire be sent through the opposite direction?
* I tried a pressurized can of carb cleaner. It blew back and I wasn't able to see where it should have been coming out if clear.
* Can the right diameter wire be fed all the way through both passages? Do both passages originate from one origin hole?
* I did not! Do I buy new cap plugs or reinstall the old ones?
* Shaft placement triple checked on install.

:thankyou:

Yes the wire can be sent either way.
I am thinking there is a passage to each end, the adjuster end and the valve tip end.
You would need to buy new cup plugs, they are 3/8 cup plugs iirc, typically one would pound a screw driver through the existing to pop them out.
To install new, ring with red Loctite and use a socket that matches the flange - OD of the cup plug and use a hammer to knock them in.
If the passage was open, carb cleaner would easily spray from each inside (shaft) to each exit. Wear safety glasses, Don’t spray in your eyes.
Ask for piano wire. Google that or stainless steel wire. Try Lowes or Home Depot. Or get an old battery cable or other large gauge cable, strip the insulation off and free one of the copper wire strands.
