54Illinois Posted October 12, 2011 Report Share Posted October 12, 2011 This engine I pulled had the pleasure of many little animals peeing on it while it was stored in a barn. The head has rust, as well as the block. What would you suggest to remove the rust? Quote Link to comment Share on other sites More sharing options...
JBNeal Posted October 12, 2011 Report Share Posted October 12, 2011 scrape the big crud off, wire brush the smaller crud off, pressure wash all the rest of the crud off, soap and water scrub the casting, apply Rust-Cure (or equivalent) on the dry casting and let it do its job...I've gone back with a smaller steel brush and scrubbed off any obvious deposits that won't take paint well and apply more Rust-Cure to make a continuous layer of phosporic acid treatment.

Dodgeb4ya Posted October 12, 2011 Report Share Posted October 12, 2011 Yes old MoPar flatheads engines do get taken over by rodents.... Another Dodge engine with the same problem I dealt with! Quote Link to comment Share on other sites More sharing options...
PatS.... Posted October 12, 2011 Report Share Posted October 12, 2011 hot tanking the block and head should do the trick Quote Link to comment Share on other sites More sharing options...
pflaming Posted October 16, 2011 Report Share Posted October 16, 2011 (edited) I used various cleaners but found Oven Off to be most helpful. Used the putty knife, steel brush, etc and then finally steamed it thoroughly. They clean up, rust, dung, or whatever. Lots of work. Got to it, it's worth it. See mine run on You tube. Mopar Dodge Flathead and Mopar Flathead-6. Instead of painting I clearcoated it five or six times. I like the "old" look and it should clean up ok.

aero3113 Posted October 16, 2011 Report Share Posted October 16, 2011 I had mine hot tanked then I used some zinc cromate primer, and aircraft engine hi-temp (500 deg) silver spray paint. For the exhaust manifold I used Rustoleium BBQ high temp spray paint (I think 1500 deg.)So far it has been holding up really well. 1 Quote Link to comment Share on other sites More sharing options...
54Illinois Posted October 16, 2011 Author Report Share Posted October 16, 2011 When dipping/soaking a block, should the water tube and cam bearings be removed? Quote Link to comment Share on other sites More sharing options...
Dodgeb4ya Posted October 16, 2011 Report Share Posted October 16, 2011 Both should be removed for the best cleaning. Cam bearings can be eaten up by cleaning chemicals. Quote Link to comment Share on other sites More sharing options...
