Snarflebits 89 HF Rebuild / Swap

Postby snarflebits » Sun Mar 18, 2012 8:43 pm

Hold on to your knickers! I did it. I bought a complete D16z6 from an old Del Sol Si off craigslist. The engine is seized up and I'm going to start to disassemble the beast over the next few days.

The Engine was originally mounted to an automatic transmission so, I'll be looking for an Si manual transmission or possible a DX.

This is my very first attempt at engine building / rebuilding / diagnosing. The engine may be FUBAR'ed but I won't know that until I'm elbow deep in engine grease.

Wish me luck, I'll be updating this thread as there is progress.

Wow look at that baby. It does look like a very complete motor.

As soon as you find a transmission you will be almost complete!

Did you get an ECU or anything else with the swap?

This should be fun, do you have any future plans or mods?

I'm guessing you just want to get the motor running in the CRX before you start thinking too far down the road.

Yep, there's a transmission on craigslist right now for 75.00 The guy says it's a CRX si 5 spd , but I'd need to confirm what year.

I didn't get the ECU but I did get the wiring harness that connects all of the sensors.

Oh man, I've got a million ideas and mod's I'd like to do. But I've got to figure out this "new" engine and get it running in the rex first. After that it's going to be time to give the car a make over.

Make sure then trans is a B000. If it says A000 stay away!

those would be the numbers for the 92-up hydraulic clutch transmission - 88-91 Si transmission would be PL3/3000
or PL3/9000

If I recall right I have had a few cable trans that said B000

i have never seen a B000 - as far as i know, all 88-91 DX/LX/HF/4-speeds say PL3/A000 - EX and ZC are also PL3/3000 or PL3/9000 - small bearing cases are A000 and big bearing cases are 3000 or 9000

Thanks guys, I'll be sure to look at the markings on any transmission I look at. I think I want an Si transmission from a crx but if you have any suggestions I'd be open to them.

Update Time!

Today i disassembled the engine. And here's how it went.

I started by taking off everything that is bolted to the head and block
Image
It looks like the valves might have some funky build up.But I haven't gotten to the head yet.

I'm new to engines but I fairly certain this may be a new one.
Image
Yep, those are acorns.... Some sad squirrel is missing his nuts.

Image

I got the head off and this was what I saw
Image

I think someone treated their engine like crap

Image

And now for the "fun" part
Image
Yep, that's no good!

Can you say AAAAAAHHHHHHH!

Image
Image

Okay, now one last picture
Image

There is a chip at the bottom of the cylinder wall near the crank shaft.
Here's a close up:
Image

So, what do you think? How hosed am I? Do you think the block will be useable with that chip? Also, there's more of that metal shard molded to the crankshaft. I'm hoping a machine shop will be able to remove it.

That's all I can do today. I'm going to relax.

Never buy a seized engine unless it is next to free. You're about to sink a lot of money into that motor.

Take it to a shop and have them assess the damage for you. May need to just have some stuff reground, but most likely will need some extra work. $$

Lesson learned right :-)b I just got so excited about finding a motor.

It may not be a total loss. Plus I did get the alternator and Distributor, If the head is good then It'll only be a little financial indiscretion.

But that waits to be seen.

Head needs a rebuild, nothing crazy. That block needs another crank and maybe a oil pump plus new rods.

^^ true that... the chip will be fine.. you can actually notch that part of the block and be fine.. you have to do it when you use some aftermarket rods..
i have 4 good z6 rods and 3 pistons if you need them.. i'll give them to u for dirt cheap...
Crank you can actually use it from another engine if you can't find another z6.. ( i forgot which ones exactly , maybe the y engines)
tip: you can actually go the junkyards by my house and you i've seen some civics ex, that bring z6.. for the whole engine they will charge you $50... take the crank from there.. :-)b

^^ CrxVtec91 - I may be tackling the head tonight, I need to get it apart to see what the valves look like. I've read a little about aftermarket oil pumps, most people are recommending OEM vs. aftermarket.

^ Tian90crx - That's comforting, I'd like to think that the whole block isn't shot.

Dang, $50.00 for an Engine! I've been doing something wrong!

I'll have to check out some junk yards then. And see who's selling what.

I think the Rods are fine, none of them appear to be bent. I'll post a picture when I get home. But if they're toast and I can't score a $50.00 engine then I'll need to know what "dirt cheap" is :) Plus, it'd be fun to meet you in person.

I rather use a oem oil pump even if it is used. Just check and make sure it is with in spec.

I think three of the Rods are still good.The exception should be the one on the right, it was the one that was seized. The parts will be dropped off at the machine shop this Friday.

When I tore apart my z6 it was so rusted inside that I broke a piston trying to tap it lol .. it wildnt slide out.. I hammered that thing till it broke the piston skirt.. It looks like those rod bolts were hit hard enough to POP them out of the rods lol

wow you sure snarfled up those bits.

I paid 1200 for a b20z2 shortblock with no head and a disgusting crank inside.

for what it's worth I spun a bearing, snapped a rod, and the piston glided to a halt in the cylinder and did NOT damage the head. The motor ran commpletely out of oil and siezed, and the head was fine. I think your head should clean up alright.

50usd for an engine :evil: and no shipping costs wtf i would build ten motors and install the one with the best compression and leakdown pressures if they were that cheap..

it's lookin good, sometimes trial and error is the only way to get to success.

have a machine shop tell you what's up with the crank and block, and get a second opinion from another shop if you want to be double safe.

my machine shop told me that my head needed a line bore and i should mail it off... i cleaned it up and i'm still driving it 10k later.

looks good!

I'm not gonna lie, I did use a BFH and a pry bar to "carefully" knock two of these out.

Thanks, Corksil. Tian90crx pointed me to a local machine shop. They were extremely nice on the phone and the reviews they have on google say they're top notch.

we are all curious to hear what the verdict on the head, crank and block are.

when the machine shop takes a look post up what they said.

Dropped the crank, block and head off at the Machine Shop today at lunch. The guy said they are really busy so, I may not hear from him until the end of next week.

I'm still waiting on the machine shop to get back with me. Me and Tian have our blocks at the same shop and they're taking their sweet time.

So, I decided to play around with the HF and mess with timing. I think it is a bit off.

While I was letting it warm up I noticed a loud hissing sound. It was coming from here:

Here's a link to a video of me plugging the hole with my finger.

Does anyone know where that hose is supposed to go? If you have any ideas or links I could read through that would be great. I can't seem to find a diagram that says's that "T" is supposed to be there.
