Assemble your own block?

Mostly because i dont trust the judgement of my 1 Honda buddy... is it really that risky to assemble your own block, or is really not that bad.
background: I have a JDM H22A i ripped apart ready to be sleeved, but wondering if I really need to have someone assemble it for me. If i have a torque wrench, and a service manual, how bad can it really be to put together right (by the book) if I took it apart?

Re: Assemble your own block?

The biggest obstacle at first is the hone.
You say yours is sleeved? As in steel? If so normal hone is good.

And since bearings have a very thin margin of error as is 1000ths of an inch of clearance for oil to pass through, a thorough check of each one to gain size of each needs to take place. To make sure you have as equal as possible clearance for oil to pass through.

Ring set is another matter.

No it's not a simple twist bolts and yer dun. There is expertice involved. But doing some research should allow you to gain know how enough to give it a go.

Re: Assemble your own block?

what is your experience with engines? Either way, you will learn something the hard way either very quickly or sometime in the near future if you think engines just get slapped together.

Re: Assemble your own block?

so basically, I could potentially do it, but really shouldn't. Or if i do, i will probably hate life shortly after.

Re: Assemble your own block?

There are tons of books (and online resources) on how to build an engine. Do some research before you attempt it. You have to make sure all of your clearances (as bykfixer stated) are within tolerances. They make materials just for checking engine bearing clearances. Do a lot research and take your time and you should be fine.

Re: Assemble your own block?

Remembering where and how everything goes is step 1..




Do you know how to measure your piston to valve, piston to wall, and bearing clearances? If no..then maybe don't put it back together yourself..

Re: Assemble your own block?

It's relatively easy when you have the service manual telling you the reassembly order, torque specs and remember, all moving and in contact parts need lubricating! Don't forget piston rings need to be placed with the gaps at even intervals before being compressed and also need slight lubrication, to prevent scratching the cylinder wall. Make sure you're taking all measurements necessary, in case a vital part Is now out of spec and in need of replacing (it's a shame it's come to that these days, parts are just so disposable), be thorough! Make sure nothing is loose, definitely do it yourself if you have the tools,

Plus there is so much more information on the internet every second you fail to research properly, best of luck to you, keep things LABELLED, CLEAN everything you inspect, MEASURE everything good against spec figures in the manual

Be sure to post lots if pictures :)

Organization is key. Since you are just rebuilding you need make sure everything goes back into where it came from.

This was more/less what I was looking for. I was thorough during dis-assembly and labeled everything. Aside from my own I have torn down other H22s and it is a relatively simple task which is one reason why i love these motors, but clearances and torques dont matter when its in pieces, roaring down the street on the other hand....
