Cleaning my bottom end.

[Dbeck002]

After I pulled my heads off, i noticed a bit of carbon buildup on the tops of the pistons. I used a wire brush and lightly broke up the carbon buildup then wiped it away. I also used a ratched and 15/16" socket to rotate the crank to push out the dirt that was in the bores. Anything wrong with the way I did that? Can I improve on anything to clean up the pistons?

I cleaned my pistons like that once

There isn't much more you can do besides carefully removing the build up with a wire brush. Just make sure it is really clean and you get as much as the carbon bits out as you can. I used Carb cleaner sprayed on a rag to clean the pistons and the bores out. Then I went over it again with a fine, clean rag with rubbing alcohol.

I use TP to clean my bottom end.

Seriously, a shop vac works well for retrieving debris in the bores.

If you were not worried about seepage, I wonder if you could soak the piston tops in a top end cleaner. Might require creativity to seal the rings totally tight.

Good luck.

I tried the shop vac method but my boxers kept getting hung

ROFL!



Ok shop vac it is... Ill try to do the best i can with the brush.


Question: What happens if soak the top of the pistons (while they are in the bores) with carb cleaner or some solvet to break up the dirt... When the carb seeps into my oil is it alright if i just drain the oil and such. Or is there a danger using solvents.. I reaaaally want to clean my pistons, thanks!!

if you choose to use solvents to clean them, just make sure you flush your oil as soon as practicable (yes, that is a word)...solvents have a way of thinning out your oil...very bad news

And to think I wondered how you got that CT.

D - I thought the Seafoam might work well because people run that stuff in their oil as it is.

Good luck bud.

EZ-OFF oven cleaner will loosen up the carbin build-up.

i just took my heads off. the pistons had a thin layer of carbon buildup. I rptated the crank so the piston i wanted was at TDC and i took a wire brush to it on a drill. i then shopvac'ed all the bores and spun the crank to the next cylinder at TDC and repeat. Once they were all done, i kept rotating the crank and wiping the bores w/ brake cleaner on a rag until they were all clean every time the piston came up. If you still arent satisfied, put the engine back together and run Seafoam through the oil, gas, and brake booster. It cleans real good.
