advice replacing worn rings pls...

I can't get this done now but I'm trying to make plans and want to run
a few things buy y'all.

I'm fairly certain that the blue smoke I'm spewing is from worn rings.
By waiting to fix this problem am I doing significant damage to the
vehicle?

Also, if I go to have the rings replaced should/can the valve seals
get inspected along the way? Should they automatically be replaced?
Can they be inspected and if found to be in bad shape replaced without
doing nearly all the work required to replace the rings?

How much does it cost to have both things done? I live in Vancouver
BC.

Some might suggest that buying a new (second hand) engine would be
cheaper but then I wouldn't know what condition the rings were in on
that engine so to be safe I should just have the rings on the original
engine replaced, yes?

The odometers was reading about 170K KM when the smoke started.

thanks

oops, major omission, sorry, 88 Civic pgmfi 5spd manual.

500 with drop in? wow, that does sound cheap. I'll have a look.

thanks

if by "pgmgi" you mean the dual point injection d15b2 engine, it's not
quite so easy to drop in the zc. you'll need to convert to 4-point
injection, re-wire accordingly, and get the relevent ecu, etc.

if you just replace the d15 engine with another, they're dirt cheap.
definitely cheaper than rebuilding your old one.

 

should also say though, if you /do/ go the zc route, that's one heck of
a motor - nearly 100hp/liter!!!

 

it shouldnt, as long as youre checking the oil level regularly. as long
as it passes smog checks (if applicable) and doesnt burn more than a
quart every thousand miles, id leave it alone and maybe switch to a
thicker oil, like 20w50.

basically an engine rebuild. those start at around $1000 and go up from
there

used japanese engines (imported from japan) generally have very low
mileage. japan isnt a big island, and people dont really do a lot of
driving there.

 

What yr and which model do you have?

You may want to check into JDM engine importers.
I know sohc ZC engines are fairly cheap and a stock drop in. $500ish

By waiting to fix this problem I would assume that the O2 sensor
and catalytic converter may be the first to go. The motor is
economically history if the rings are worn. There may be a
deformity on the cylinder walls, and simply replacing the rings
won't cut it.

Most decent place will sell motors with a tag showing their
compression readings. Usually 180 psi on all four is a good
motor, but rare. If they read different, avoid them (eg. 180, 160,
175, 162 psi)

 

Hi!

If you live in VC, you should drive down to Richmond and have A&J
Racing swap them out for you. If you think your rings are leaking, do a
leakdown test to make sure. Regardless, old engines need a facelift - so
swap out the rings, make sure you have them clocked correctly (90
degrees appart), and swap out the valveseals and guides too. Better
safe then sorry.

 

very interesting that you passed emissions running a zc and dpfi!!! i'd
love to check this out for my 89 civic hatch automatic, but i suspect
lack of egr will be a problem here in california. have you ever heard
of someone with this kind of [california legal] swap? [automatic is a
must.]

 

HI,

The ZC is one heck of a engine. 128HP vs 96HP. It's a noticeable
differance. I had one in my old 90 Hatchback.

You could run the your DPFI intake on the ZC w/o any issues. I still
passed the e-test with it on my zc.

Going from DPFI to MPFI isn't too hard. You can keep your ECU.
You'll have to get a few more parts and re-pin some wires on the harness.
Just google search DPFI to MPFI . There's a lot of info on how to do it,
parts needed, etc.

Make sure you replace your t-belt, tensioner(maybe), & water pump with the
engine out. Also install a new clutch.

$500ish engine $200 for t-belt/waterpump, $200clutch kit, MPFI if your
decide to go that way $20-$30MAX from the junkyard.

You may want to check out www.hondaswap.com fourm. There's a lot of info
there. Just make you SEARCH before making a post.

Also I would stay way from the DOHC version. It's a lot harder to find
parts for. SOHC ZC basicly shares parts with the Si D15/D16 block. ie. same
t-belt, water pump, etc.,

I don't know about cali. and engine swaps.

Since your using your old intake manifold I don't think it should be a
problem.

I really don't know 100% for sure.
