Bryan,

outta curiosity could you e-mail me. I would like to talk to you about your service, location cost etc.

Thanks,

Thanks for the kind words Don. I spent some extra time on your stuff.....as you know.

With my machining practices, I have been able to use Clevite bearings in the Honda engines unless there is just some crazy problem with the main bearing bore size.......I can repair that as well.

3% leak is very good considering the kind of driving you do. I am too much of a perfectionist. I try and keep my tolerances to .0002 on cylinder bore taper, rod taper and out of round, and main bearing housing bore. It is very difficult to maintain, but that is just how I am.

Thanks John, I value that advice. My friend helping me do the work is a helicopter maintenance engineer and worked up his h22 prelude engine....though it's not the same thing I do trust him and am eger to learn.

I guess another thought is, the car has great compression, run's clean, is it worth doing the bearings. See, I read in the Haynes manual that some of this stuff should have a Honda do, because they have all the right tools (that was the long and short of it). So if it ain't broke, don't fix it?

Forget NAPA for Honda bearings, they will sell you a generic set, not "coded" bearings. Adrian is correct regarding the codes they are SMALL increments used to "fine tune" the clearances of each journal fit. Thus it is possible to set up a motor on the loose end(tolerance range), for a quick wear in, i.e.for racing purposes, or on the tight end side, for longer engine life...but a more relaxed wear in. This is due to the fact that Honda first started building Motorcycles and carried over this vastly more precise way of building a bottom end to their Automotive efforts.
Also any time you are re-building a Honda Motor it is wise to start with a "green" code main, and rod bearing set, and use them with plastiguage to check ALL main and rod journals for actual size. On used motors you can't always trust the origional code numbers on the Honda parts.
If you can't make sense of this, I would strongly suggest you find someone who can, and is willing to do this right. The bottom end on a Honda motor is everything. Done correctly,it will last a LONG time as long as you keep proper oil pressure, good oil and don't overrev it. If the bottom end is built incorrectly....forget it, you just threw away your money.

The bore and journal size numbers/letters won't mean anything to anybody except Honda.

By nathan (24.85.232.159) on Friday, July 08, 2005 - 08:57 am:

Adrian, alright, I will log those numbers and take them to Honda, and or NAPA.

Bruce, I will check out colt cams for a mild cam. I definately agree...it's open, I want to try and do it all right, replace what I can.

Don, I understand what you're saying....but, this is a learning project for myself, girlfriend and best friend of years. Jan my buddy is a helicopter licensed matenance mechanic and is the one who got me thinking past welding and bondo. So we want to tear it all part, learn, laugh, re-build it up. It shouldn't be to hot that anything will grenade...though you had great imagery on that and the mechanic ... it will be a mild mod engine, just for street, really fun city car and easy goin highway cruise. I agree with what you say, but for now, we're trying this out and tryin to learn

BTW there is no such thing as oversize bearings made by Honda.

By Adrian (Evocivic) (203.217.68.66) on Friday, July 08, 2005 - 05:33 am:

The colours are NOT to denote undersize (or over size if you like) bearings.

Honda measure the bearing bores and journals to very close tolerences and have a range of colour coded bearings of minutely different thickness to match different bore/journal size combinations to get the clearances spot on. The differences in dimensions we are talking about here are very small ... microns (ten thousandths of an inch, not thousandths).

By bruce (4.159.178.107) on Friday, July 08, 2005 - 05:22 am:

the colors are size's not cylinders, standard, 10 over, 20 over ect. send the cam to colt cams, he has all the dimensions to make a cam mild or wild. www.coltcams.com. If your motor is open already you would be better off doing it all, bearing can still be ordered thru parts store.

By Adrian (Evocivic) (203.217.68.66) on Thursday, July 07, 2005 - 04:01 pm:

Shave 5 degrees ??? ... what does that mean?
You never reduce a cam's duration you increase it. You also won't get much out of having huge lift, these engines prefer duration.

The colour coding on the bearings has nothing to do with which cylinder they are for. There is a line of letters stamped on the block (e.g. BBBCB) which tells you the size of each main bearing bore. Then there are numbers stamped on the crank webbings near each journal which tell you the journal sizes and numbers on the rods to tell you the rod bores. You take these numbers for each bore/journal combination and look up the chart in the Honda workshop manual to work out which colour bearing you need for each journal. You can only get correct colour code sized bearings from Honda and they are very expensive if you can even get them any more.

Send the Engine to Byran Maloof I shipped the 1200 cross country and it was about a 100 bucks each way. Wait..... dont say you cant afford that! After trying one podunk shop after the other (50 year old machines, brain dead, alky machinists) I now send my important work to Bryan. Bryan knows his stuff and takes the time to do it right. 200 is cheap insurance considering what it will cost when something grenades, Or leaks I did a leak down on my new head and 2 year old bottom end and its about 3% ....you wont get that from a local machnie shop it takes $$$ machines and skill.

By nathan (24.85.232.159) on Thursday, July 07, 2005 - 03:29 pm:

no one? Adrian....Justin....Don?

By nathan (24.85.232.159) on Thursday, July 07, 2005 - 08:29 am:

All the build parts are pretty well here now for our EB2....but I have a few last questions and parts....

For a mild modified EB2, where should efforts be on the cam? is it better to shave 5 degree's on the stock cam (I blelieve that was a RS cam)? or buy a new one?

Before I get to the bottom end bearings, I understand the go by color code. Anyone know what color's are what? (Red - cylinder one, blue - cylinder....etc.) I would like to replace these while it's all open....any upgraded ones maybe?

If anyone on the board has these items to sell, I would prefer buying from the group here, than just some store...

Anyway, the project is coming along great! Without all the help I'd still just be a body man
