I ustabe crabby until I realized I wasn't Olympic material. If you cant reach the gold ring, and mediocrity isn't an option, might as well ride the bleachers.

Been working away with compressed air and picks and have a lot of that stuff out. Got the head pretty well cleaned.
Mice were in the no. 1 cylinder so that end of the head is a mess. Can't get the spark plug out yet. That bugger is almost welded in. More phun to come! Not a rush project - leave some work for the cooler fall days.

A continuous flow of water will do it if you can get enough flow. I've flushed a lot out just by adapting a garden hose to one of the coolant pipes and let her run. The hard part is getting the volume. You dont necessarily need lots of pressure.

Don't use muriatic acid! Its the gift that keeps on giving!

For the cylinder blocks on my big T-head Wisconsin I soaked them in a hot Lye solution to de-grease and remove as much paint, dirt etc. as possible. You want it as clean as possible!Then I used diluted Phosphoric acid for the rust.

I smeared grease in the bores and any other surfaces I wanted to protect from the acid. I fully submerged the blocks so the water passages were treated as well.

It worked wonderful and leaves a protective coat that's perfect for paint and will not rust-up immediately like muriatic acid will. In addition with muriatic you must make sure to rinse the parts off completely! And.... when you do that they immediately start rusting again.

I had great luck cleaning the individual water jackets on a Holt 45 last year. They were packed in the bottom and would not let water flow. The common galley in the block was also solid from sitting. I did not want to remove the cylinders to clean. I used a couple feet of small copper tubing and adapted it to a pressure washer tip and hammered the end flat with a small hole in the end. The copper could bend easy and feed down the passages of the cylinders to break up the solids.
It could poke into the small crevices and blast it out good.

if it was me i would think very hard about dropping out pistons and pulling liners very easy to do with the block still in chassis least you get a good look at rings and big ends whilst you are at it.

You might try Rydlyme - we use it at work on heat exchangers and it works well without degrading the metal...
