I got some dust and little bits of leaves sitting on top of the pistons and walls, can I just get like an air compressor can and just blast it out?

 

at least remove it by hand if you dont have air. put a generous amount of oil in each of the cylinders. Then crank it over by hand and remove the rest of the debris. Then put your heads back on before next fall.

 

nono I meant like go to office max and get that compressed air stuff and just spray it all out, would that work?

 

to an extent yes, but putting oil in the cylinder and turning it over by hand will leave all the microscopic dust and debris still there after the air spraying in a ring at the extremity of the piston travel for you to wipe out. clean that out with a brand new paper towel or terry cloth. No napkins or anything that will leave dust (not that it's incredibly harmful)

 

are you saying i should use oil and towels to get rid of it instead of air?

 

if you want, pick the big parts out by hand, and then oil up the side walls, maybe some wd40, just to coat all the sides so that the piston rings are coated, and then do that to all open/affected cylinders, after each cylinder and cylinder wall is nicely coated, turn it over and let each cylinder come to the top and go back down, wipe up the crap, and close it all back up so nothing else ever gets in there other than fuel and air (while its running of course )

 

thanks for helping me you made me feel better.

 

Dry compressed air would be best. After removing as much debri as you can by hand. You dont want to send it flying into the cam valley where it will end up in your oil either. The mechanical cleaning being suggested will probably leave debri in the gap between the piston and cylinder above the top ring. Any foreign material in the cylinder can cause scuffing and reduce ring seal. If all you can do is the canned air, remove as much debri as you can by hand and then use the air for fine cleaning. Then, as suggested, lightly coat the cylinders with oil and get the heads back on. In the future when you have a motor torn down, cover it tightly to prevent this kind of contamination.

 

i would use light air and maybe a thin amount of Kerosene on a microfiber rag and be very very gentle and careful. Or i would just get the heads redone. Any type of micro sized anything could scratch your cylinder and make the whole thing smoke like crazy from the amount of oil it gets

 

i need to know why nobody suggested to just pick up the block over your head and shake vigorously until all debris fell out

 

Oh man! Why didn't I think of that!

 

Like the rope trick to keep a valve from falling out, use a 100% cotton rag for a wipe down. Use like wd40 on it to grab stuff, any cotton fibers left behind will burn off clean.

Thats what I was thinking too
