Keep sanding or will new gasket seal?


Also, where can i find camshaft bearings? tried rock auto, and ebay, amazon.... do bearings not exist for this design? ( havent taken apart cylinder head yet)

No bearings in the head that I know of.

As far as the fire ring its a good question.

Didn't want to take any chances so spent an entire day getting the impressions out of the block.

Time to see how nasty the cylinder head is now

Head has no bearings, just a "bearing surface" as it's called.

Were you having problems before?

No but I can only imagine how that can become a problem in the future. Small crack in between the combustion chamber and coolant jacket. I did notice there's oily residue inside the block But when I drained the coolant it looked fine as well as the oil.

I ordered a used one from eBayI want this car to last and I'm doing as much as I can to assure that. Gonna check flatness, valve seats, valves and regrind if need be.. change seals...

My ghetto "refresh"
New crank bearings, rod bearings, new pistons and rings, hone walls, new front crank seal, all gaskets, new alternator, new ac, new oil pump, new water pump. For starters. Might as well replace the starter while its there and may buy a new distrubutor and iac valve. Hopefully the sensors are within spec still. Going to check head for flatness

Once I have peace in mind that everything runs, I will work on the undercarriage/ suspension and Steering. Ultimately I will replace the transmission even though it shifts well

Out of curiosity, where are you getting the new IACV?

I havent looked yet so I dont know. But by the sound of your post they are completely obsolete? Lol

Well there's this one (https://www.ebay.com/itm/New-36450-PK2-023-Fuel-Injection-Idle-Air-Control-Valve-for-Honda-Accord-Prelude/292218045261?fits=Year%3A1989%7CModel%3AAccord&hash=item44098d834d:g:wtAAAOSw~6BZlXaJ), but yeah. I was hoping you knew something I don't. I'm heading to the junkyard one of these days to test fit alternatives. The only problem is that 3g's are getting scarce in the yards around here.

there's https://www.beaverscarsalvage.com/ in my state as well. I've gotten that thermostat housing, a crank sprocket and water pump inlet pipe from them for a reasonable price delivered in good condition. But, if you can find a salvage yard with the parts thats much better, pick and pull. I dont have one around here locally with 3geez. I have a question for you.

Did your 3gee come as an automatic or did you convert to a manual? if so how did you do it?
also regarding that valve, does it fit a 3gee? i cant select the trim make and model for some reason.. wait a minute, 200+ bucks?

I swapped following this thread: https://www.3geez.com/forum/how/102-convert-automatic-manual-transmission.html

That's actually pretty cheap for the IACV. They used to be over $300 when you could still buy them from Rock Auto. You can try cleaning the one you have. That helped mine. Just Google for it.

Im interested in seeing how you did all the work to the block surface. Did you take any pictures?

Donnyten

The only pictures I have are the ones in this thread. For some reason they don't show on mobile devices unless you switch to desktop view or your on a desk/laptop

Did you use a plate of glass and sand paper? Thats how I have seen it done.

I used the flattest piece of wood i could get my hands on.. started with 80 grit, then used 100 grit, then 120 grit. I just recently did my cylinder head the same way. probably gonna touch it up again. but this is how it looks now. looked horrible before

Nooice. Now clean out the chambers, give em a solid polish. Do the same to the ports. She'll flow like butta.
If you have the spare cash, take it to a shop and have a valve job done, new guides and all that.
There was an old thread about a guy who used exhaust springs on the intake side. Never did get around to it when I had the Prelude cause that ended up totaled >.>

What was the reasoning for having the exhaust springs on the intake side? I would get a valve job done but im on my last dollar. I thought about lapping the valves though. Thats the least i can do i suppose. I also have new intake and exhaust seals as well.

I believe it was so he could go up to 7-8k rpm and the springs would hold up...
It may have been on preludepower... I'll have to dig it up.

Took me a minute to find it. Was this guy: http://hondaroots.com/2013/01/02/rotm-january-richard-judges-85-prelude/
He used to be on here all the time but guess he's gone now. The old fogies would remember him.
I wish there was a way to contact him so he could help me with my dcoe setup.
