Blew tops of pistons

Do you guys have any ideas on how to het them to stop leaking? Idk why but I can't get them to sit right. I feel like there in all the way but when I spray carb cleaner a couple bubble still
 


You'll have to replace the lower o rings. Best bet to replace both upper and lower of course just for insurance.

When you put it all back together though use some kind of lubricant to get them to slide in whether it be silicone spray or grease. Silicone is what I use especially if the seals are rubber because petroleum products will eat the rubber over time. So don't use engine oil to lube them up.
They'll never sit properly if they're dry.
 
Alright ill give it another try when I'm off. Also does that seem right that it would bubble if there where a leak there. My ltfts changed from 16.4 to 11.1 and back up when I sprayed around.
 
Alright so i tried new o rings and nothing. But now when i drive it will go to negative 3.2 then when i let off back up to 16.4. I tried ressetting the battery to start fresh and nothing. Any ideas?
 


Any ideas on why its going from -3.2 while driving then 16.4 while idle. I think its something with the injectors cause when I spray it'll go down to 4 at idle but I've tried changing o rings and nothing
 
So I changed my uim gasket and put new oil on the super. When I fired it up it smoked like crazy then quit. My car now runs rich -22 when cruising and still lean sometimes but not as bad. If I give it some gas it goes to zero. What could cause it to do this I only changed that one gasket. Could it be my maf sensor cause when I unplugged it car ran the same. Please help.
