So I replaced one of the pistons (new piston head and new rings) in my 79 GT (its running a 72 302) ,, and I didn't hit the bore with a hone before putting it all back together. Well it runs but I am pretty sure not hitting the bore with a hone is biting me in the ass because I have some pretty serious blow-by now.. except if I dribble a little trans fluid into the plug hole. If I do that (and purge the excess fluid out of it) and put the plug back in and start it up it has like zero blow by.. until I try to spin the tires then I am back to blowing out of the pcv like crazy. So I figure that is from the new rings on the glazed cylinder.. So the question is, after reading some other places on the internet talking about all sorts of solutions (including the bon-ami ones) I am trying to decide if I really have to tear it back down, get a hone coming from amazon and do it or if anybody will tell me that they will eventually seat permanently and it will be ok. I really kinda don't want to pull it back apart again, and it's cold out. Anybody? (should I just suck up?) Thanks.
