Engine cleaning complete and a redneck, lowbuck parts washer

The engine is now squeaky clean. 3000 PSI pressure washer, Purple Power and a turbo nozzle do wonders on grease, mud and anything else that doesn’t belong. Also found that I have a piston that not only has a chunk out of the skirt, but also a section of the ring separator that broke off. There were also 4 broken compression rings. Good thing I tore it down.

Now to I need to see if I have a spare piston of the right part number and weight. I really don’t want to buy new pistons, unless I decided to make this an all out build.

Now I don’t have a parts washer. The one we had in Statesboro stayed with Ditch, he had bought it. It was also too small. Well I am going to pick one up in next weekend’s HF sale, but I wanted to get the pistons and such clean now. So I concoted a low dollar, high speed parts washer.

Ingredients:

  • 5 Gallon Bucket
  • 2+ Gallons Purple Power (or white lighting, simple green, etc)
  • 2 Gallons Water
  • Drill (Cordless is easiest and safest)
  • Plastic, Squirrel cage style paint mixer ( http://www.discountpaint.net/store/product.php?productid=7035 ) Available at home depot

Mix the Purple Power and water in the 5 gallon bucket. I would put about 4 gallons in the bucket. More cleaner = more power, but 2/2 is about right. Put the parts in the bucket. I found about 2 piston/rods and 1 main cap in at a time. Let it soak for about 20 minutes and then using the drill on torque setting and use the paint mixer to agitate the solution for about 1-2 minutes. Remove parts, rinse and dry with an air gun. Cleans parts well and quicker than a parts washer.

Note: this will clean oil/grease. To clean carbon build up soak time must be longer. In that case one could use a drill press to keep the fluid moving longer, not real efficient though.

Engine Tear down and a new specialized tool

The jeep engine has now been torn down. Overall pretty good, pics to come tomorrow. Tim helped out alot. Bearings look good, only major issue is a chipped skirt on 1 piston. Explains the metal piece I found in the crankcase.Tomorrow I will pull the freeze plugs and get down and dirty with the pressure washer and some Purple Power. Trip to Summit Racing is in order next week to pick up the parts I need.

Also I picked up a tool that before a couple weeks ago I never knew existed. A ridge reamer. It is a manual carbide tool that cuts the ridge at the top of the cylinder down so it matches the diameter of the rest of the cylinder. I really like these kind of tools that do one thing, but do it really well. Also, looking on Amazon they run about $60-70. AutoZone has them in their rental program for $35, which you get back if you return it. I may keep mine though, it did a really great job.
