My engine's apart, and I've noticed grime/rust on some of the internal components, like the rocker arms...I've read many tutorials on this forum, as well as engine rebuild threads, and the parts that they show on their pics are not nearly as worn-out looking as mine are...

What is a good, safe method for cleaning the engine internals before putting it back together? Thanks!

 

if you can find it soem navel jelly and a stiff brisstled brush. if not some CLR from your local hardware store and a stiff bristled brush.

 

I've always used Kroil and the softest brush that will do the job, never tried it on engine internals though.

 

PB Blaster cuts the rust.

 

Thank you for your suggestions!

 

plain brake cleaner will also do. blast away the rust and dry the parts with compressed air!
