Engine Gunk

[49 Caddy]

  Anyone ever concerned about getting all debris/gunk from in between the 2 layers of metal the valley cover is made of.? Just rebuilt the 331 out of my 49 Series 61 and don't want to allow any debris into the fresh insides.  I have shot carb cleaner and garden hose pressure into 1 hole and it comes out the other.  No matter how many times I do it,  I get debris.

I took mine to an engine rebuilder who put it in a machine in which he cleaned engine blocks.

  Every machine shop I go to, pressure washes engine parts now.  E.P.A. rules/etc...

A couple application of oven cleaner will help as well! The caustic stuff.

Evapo-Rust. One quart about ten bucks. Get a cheap Tupper type ware container from DG or Wally about the size of your part & dunk it.

  Thanks for the responses.  I have it in a tub of Rust 911 now.  If results of that are not satisfactory I am going to try the oven cleaner as suggested.

  Thanks for the oven cleaner recommendation, that did the trick.
