Cleaning out the engibe

Postby DeeF88 » Sun Oct 16, 2016 7:12 pm

Been taking apart my newly acquired 1949 Farmall cub, taking it apart and cleaning/reprinting/fixing parts, I'm on the engine right now, any ideas on cleaning out the engine? It's got some old gunk in it, but I don't have much experience with engines, any pointers on cleaning up the engine or what to run through it to clean it, I don't want to hurt the engine or screw it up, all advice greatly appreciated! Thanks guys!

I would only do a couple of rapid changes of engine oil and the oil filter.

I have used a product called Rislone Engine Treatment. But, this was back in the middle ages when most vehicles used non-detergent oil.
I have an excuse. CRS.

Remove the oil pan, and scrape out the sludge. Be sure the oil pump intake screen is clean. Then, do several oil changes, as suggested by Eugene.

In addition to Ed's suggestion, you can also remove the side valve cover and remove crud from there. You really don't want to use anything aggressive to flush it. Any crud you can't get out by these means is best left alone.

Had you posted this before you started I would have recommended the system I use on an old engine I am preparing to rebuild. I put about 1/2 to 2/3 of a can of Sea Foam in the oil, and the rest in the fuel and work it hard (mowing, plowing, or whatever you need to do) for 2 or 3 hours. It is amazing what that will do to clean out an engine. If it hasn't had the engine rebuilt recently it probably needs bored and new pistons, crank turned, etc. Note, I only use part of a can of Sea Foam due to the fact a cub only holds 3 quarts of oil. On a bigger crankcase it would be a full can.
If you are not part of the solution,
you are part of the problem!!!

When I cleared the gunk out of mine, Eugene suggested making something like this. It worked pretty well!

I think that tool that Eugene suggested is used for clearing gunk out of the waterway
