Reply To: My EVAPO RUST experience

[Edgar Minnie]

Evaporators rust did not cause your problem. I have used it on many projects. Evaporators rust removes oxygen from the rusted metal, causing the rust to dissolve, it won’t cause any issues with anything. I have had heads stuck like yours, and ended up using an engine crane lifting up on the head using the plug holes, and taking all the weight off the front end so the tires are just touching the floor. This head did not have any broken bolts or studs, just stuck from years of sitting. About one week later we were in the shop and heard a noise……it finally came apart after hanging there for quite a while. I have seen heads crack and removed in sections. I think the issue you are having is people out west often run only run water with lots of minerals in them causing lots of problems. I never buy spare engines from areas where they usually only run water as the blocks tend to be rotten from sitting for years with just water. The inside of the head and block should be clean after running it…..was it? Also, if you remove the water jacket cover, expect the same issues. Ed
