Well i picked up a 305 from a member on here...im going to just put all my stuff on it since my 305 locked up...but my question is i wanna make sure the cylinders are clean since my geneius wife left the garage door a bit cracked this morning and its windy and some dirt got in there how can i clean them up? without taking the pistons out..cause it came with the crank pistons and rods..thanks.

 

Are we talking a short block? If so put it on a stand upside down and spray out each cylinder with contact cleaner or brake clean. Don't be cheap with the cleaner. Then coat each cylinder lightly with oil. I would try turning it over very slowly at the point to move the pistons maybe a half inch. Look at all the cylinder bores that have pistons moving down to see if they are streaking which would be a sign of dirt. Now turn the motor back the half inch and check the other four bores for signs of scrapping on the cylinder walls. If you see nothing you should be ok. The wrap the bloody thing in plastic and tape it up until you are ready to install it. Don't blame your wife for you leaving an open motor out. That's on you. I don't care where you put it. Even in our rebuild shop at work motors get covered at the end of the day if anything is left open.

 

Dude chill ha ha u sound like my dad lol but its no problem ill get them clean.

 

dam i just checked one of the cylinders and the dirt scratched it...em i in trouble this blows..i really didnt wanna disamble it...its just like 3 scratches not bit but i dont know if this will affect it...

 

Clean it some more. It very likely won't be an issue. The big worry would be premature ring seal failure. Even if it is truly a scratch if you can contain it to a very small area it shouldn't be an issue.

 

as long if its not cracked or anything right? its just going to take some cleaning and time i covered it already though i got an engine stand right now so tomorrow ill start to clean them..i gotta replace one piston anyways..thanks again man for all the help i was like **** i just messed another motor up ha ha
