CALC!_JUST_du_IT!

Ok, so I'm a bit intoxicated right now, and I thought this would be a good time to work on my motor rebuild that I've dumped thousands of dollars and countless hours into... Just looking for some corroboration on some info I was given; I was told the piston to wall clearance for forged pistons should be 0.192". To me, that seems a bit large. 0.0192" seems more appropriate, but this is my first engine build, and the mechanic who told me 0.192" is a lot more experienced than I. So, anyone here who's successfully rebuilt a honda motor (mine is a D16y8) with forged internals, which sounds more accurate: a piston to wall clearance of 0.192", or 0.0192"?

I've checked the clearance. It's about 0.020". It's really a snug fit, but i feel comfortable knowing the rings will seal well without being over-exposed to the force of the cylinder combustion... I'm just concerned that if the pistons don't have enough clearance, the friction will cause them to melt, and possible destroy my sleeves.

Any help appreciated. Thanks.

its gotta be .0192 in.

.192 in. is getting close to 1/4 inch, so that is definately not the correct answer

it's pretty sad when a drunk member can post better than 90% of everyone else in here lol

bense is right you do post better than 90% of posters here that are sober.

Wow... I hardly remember posting this, but thanks for the help. I just talked to my mechanic again; he said 0.0192" was what he meant to say.

So, is it normal that the piston has to be forced into the cylinder, even without rings? I've seen horrifying images of pistons that have melted due to the friction against the cylinder walls.
