Following a link posted on another thread, I found this article (among others) and it addresses something I've read about here on USMB; Pulling the rocker arms and servicing the hydraulic adjusters. My '95 has at least one ticking lifter and I'd be very happy to quiet it all down.

 

So many here have said to just flush the flat lifters rather than replace them. Why go to all the trouble of removing them but then not replacing a wear n tear part?

 

And at the end of the article I linked to, the author referances cleaning oil passages - His pics were informative. I had no idea the oil passages I'd be looking for were so small!

 

 

With the rocker arm assembly out, exactly which passages should I be looking for? Will it be just the openings on the surface of the rocker arms? And are they expected to be only clogged at the surface and easily cleared? Or are there passages which require Roto Rooter equipment to properly get flowing like new?
