So, I think this is a dumb question, but I assume all of you will understand why I'm asking. Are the R75/5 hollow pushrods supposed to supply all the oil to the upper end like many other engines?
I've rebuilt hundreds of VW and Porsche 356 pushrod engines, but I'm rebuilding my first /5 engine. Usually, the standard check for pushrods is to blow compressed air through them, to make sure they're not clogged. Well, the /5 pushrods seem totally clogged (the engine did sit for years), so no wire will penetrate the ends. They were immersed in Safety Kleen last night, and in desperation, I even tried a 1/16" drill bit, but no go. It's almost as if the holes were never drilled all the way through those hardened tips, but if that was true, I assume the rocker shafts and valve stems would've seized up long ago.
Thoughts on this quandry? New ones are $260 a set.
Thanks, Fred Heiler
