I got a real shock last night while measuring my ring gaps for my B16, top ring is .0023" and second was .0027". I open another pack of rings to make sure I didn't get a bad set, same thing. I then went to the 2nd cyl and got the same results.
Wiseco recommended spec's for 82mm are between .0013" and .0016". I cannot bore my block anymore as the next size up in pistons is 83mm and will require sleeving.
The machine shop had all of my parts (pistons/rods/rings) while they bored and honed it for balancing and blueprinting (which I never got the spec's for they just told me it was within spec), so there could not have been any communication error on my part. Are they responsible for replacing my block? I would hate to eat the $600 I paid them on top of buying a new block and having it machined again.

 

youre d*mn right they are responsible.. if they are a reputable shop, they might help you out.. maybe not buy you a new block, but maybe some more machine work free of charge?? if i were you, i would buy sleeves and have them put them in for free.. hehe..

 

Have you actually measured the bore diameter and p/w clearance yet?

I do not have the extra money to buy sleeves that I do not need. I would trust very few places to sleeve a honda block, with the possibility of a sleeve sinking.

I do not have a bore gauge, I planned on taking the block to them to measure the Dia. and seeing what they can/will do.

 

its either sleeves, or new pistons or SUE THEM! ehhe jk

Pistons are already max size. Would you trust them to sleeve your block if they cannot perform a simple bore/hone?

 

definitly not, but it depends on how the mistake was made, by accident or just pure careless . either way its a problem that needs to be fixed, after having one problem i would aviod doing biz with them to create any further problems.

just have benson,darton,GE ect sleeve your block.

i would definitly hold them respondsibale for the mistake that was made as there seems to be alot of money just being thrown away, they cannot expect you to use a ''damaged'' block as being overbored too much is considered damage if your pistons are maxed out.!

 

well i had a problem with that once, and the machine shop just got me a new block and redid the hone/bore. well i went 82.5mm nippon CTR type piston and it was still reliable

 

^^That's what a good shop SHOULD do. They offer to replace your block with new machine work, free of charge.

The important part is how YOU deal with the problem. If you go in all pissed off and yelling at them, they're going to be far less likely to be helpful. Just calmly and politely explain your problem to them and ask them to fix it. If they ask what you'd like to see done, tell them you'd like a new block re-bored to the proper spec. If they have a problem with that, take them to the Better Business Bureau. You gotta be a bro in order to get the bro deals, remember that when dealing with sales and service people.

So you don't even know what the exact dimension they bored it to is because you don't have the proper tools? You are infering that it's bore is too big because the ring end gap is too big? Get the shop to measure the bores and then go from there before blaming it on them.

 

I spoke with the machine shop today and they were very polite, they looked at my spec sheet and measured my block. I told him about my ring gap problem and told them that I had even tried another set of rings. They suggested that I call Wiseco and make sure they did not have any other issues like this.
I left the machine shop and called wiseco on my way home. I told them my problems and what the machine shop had said, they asked what the measurements from the machine shop were. Turns out the machine shop had not read the little note in the box concerning coated pistons and not to add any clearance to the bore. So I now have .005"-.006" piston to wall clearance instead of .0025"
Already half way home I called the machine shop back and told them of my problems and they seemed to want to help. I will not be able to get back to the machine shop until Thursday to see what will be done.

 

Edit. Damn I need to learn to type faster.

I do not build enough engines to warrant the price of a quality bore gage. The machine shop had the required dimensions but failed to follow the directions that came with the pistons. Yes I inferred the bore was too large due to my double spec ring gaps, I took a hunch and was correct after proper measurement.

 

You know... as rude as it may sound. I think it IS the FAIR & RIGHT thing for a "company" should do. They owe you a comparable block that is useable for the setup that you gave specs for. Machine shops are supposed to do precise measurements, which takes attention to detail. If it was something that didn't take precision & great attention to detail, everyone would be drilling them at home with their hand drills. Okay, the last statement is far fetched... but they didn't read the instructions. They have wasted your money & your time.

Maybe someone here on honda-tech is sending out their block to get sleeved, and you can just swap them and your machine shop can redo the work and do it right this time.

 

You live in tyrone? I know a few people from there, ones actually a machinist too haha.

Sorry, I wasn't trying to slam you or anything. What I meant is what a couple of other people had said - don't go in shooting and ask questions later, it will get you nowhere. You obviously handled the situation well and it sounds like the machine shop is willing to work with you on a fix.

I agree that they should either sleeve the block for you or find you another one. Any reputable shop will admit when they have made a mistake and take steps to make it right.

 

Yes sir I have learned that you get much better results treating some one like you would like to be treated yourself. Getting nasty is saved for the last resort.

But it feels so good to show your real emotions sometimes... you can always apologize later.. hahaha

 

A machine shop over bored a friend's block. He made them buy him another block to replace it.
