I have a 318.....I'm going to pull my engine to replace the oil pan, and while it's out I want to give the dirty mess a thorough cleaning.  Are there any big no no's to cleaning an engine, outside the obvious keeping water and degreaser out of intake and exhaust?

I would also try to keep the degreaser off the ignition coil and charging system electrics if they are still on it. Other than that not really an secrets; just get some good degreaser and an old toothbrush works pretty good to get down in the cooling fins.

I would just suggest getting the fins as clean as possible, and make sure there is no residue on them when you slap it back in.

Gas is cheaper, and better, than most engine cleaners.  I use the old stuff I take out of things that I fix.

Bug and Tar remover also disolves or cuts the grease pretty quick.

I agree cleaning with gas like mentioned, that's what I use most of the time.

If the 318 has the Kawasaki engine in it there is an electronic ignition module on the left side (facing rear of tractor) at the back.  I'd cover that up.

Story goes that in WWII, the air force guys used to take aircraft fuel and wash the planes with it.  I was told it would take off bugs, crud, and junk that nothing else could.  One guy told me that he had seen it sloshed onto hot engines, and he was always surprised he lived to tell about it.


That was during the gas shortage in the states, too!

gasoline was first use to clean things - before they started using it in engines

When I redid my 120 prepped my engine for paint with the following steps:

  • power washed with all tin in place (after removed from the tractor and was careful to not get electrical parts wet when possible, especially points)
  • removed tin, sprayed all parts down with Simple Green, scrubbed with soft bristle brush, rinse with power washer under low pressure
  • removed old paint with wire wheel and wiped down with tack rag
  • Repainted block with high-temp paint (taped off head and left bare aluminum) 
  • Painted tins with regular paint that matched the high-temp stuff on the block
  • Reassembled and installed in the tractor

I used JD Muffler black paint for the block and JD Blitz black for the tins.  There is very little difference in color and shine on these two paints.  Over time the paint on the block cooling fins has dulled a bit.  As of know I believe the engine has about 50 hours on it since the resto.

Oven cleaner is good for paint removal for the block. Not the environmentally nice stuff though that

smells like lemons. Use the old fashioned stinky stuff.
