d15b7 vs b15b7

hi all,

among my newest woes with my car..lots of smoke and such again.
have no idea how it happened this time, no overheating, nothing. all
my radiator fluid is gone, but the oil isn't milky and smoke is coming
out the tailpipe like crazy.

anyways, theres a guy selling a b15b7 in town for 200 bucks. my car
had a d15b7(civic lx). anybody know if this is a straight bolt in and
what kind of engine it is?

i can't afford a jdm or another vehicle at the time, so this is as
good as it gets for me.

thanks,
ricky

You sure it's a "B15"? The smallest B was a B16. And there was never a
"B7" version.

Check the engine number again. It's on the flat pad on the front of the
engine block where it meets the tranny bellhousing.

The CRX had a B16, so it ought to fit pretty closely. BUT... you'll need
ALL the sensors, the injectors, the injector resistor, the ECU and the
entire wiring harness from the B16's original car in order to make the
swap. You may need the axles as well. It won't be cheap in terms of your
time, I can tell you that. And you'll have no end of trouble trying to get
all the bugs out.

I think you may find it easier to just get the head gasket replaced in your
existing engine, or find a used direct-swap from a local wrecking yard.

 

I agree with Tegger, sounds like a failed head gasket. Replacing the
gasket will be much cheaper than replacing the engine.

 

I would be ok with replacing the gasket, but i've done that about 3
times already on this engine. it's always been a bad thermostat or
something that screwed me over. soo, i think the engine is
toast..replaced the pistons rings in may, along with gaskets and belts
to try and fix an oil problem. still wasn't fixed, i think its
blowing thru an exhaust valve seal as i use up a quart of oil per tank
of gas and oil spots all over my trunk. i think the engine is toast..

 

But was it done WELL? Do the job less than perfectly and it will fail
very soon. There are pretty high pressure loads happening about
20-times-a-second in each cylinder, plus there are heavy thermal loads
with the heat-cool cycle.

Have a garage do a blow-job on each cylinder to find the one that makes
bubbles in the rad filler neck.

Oh, it's that bad, is it? Then call your local wrecking yard and ask for
another of the same kind of engine you've already got. Even if they
don't have one on hand, they can get one shipped in.

Or you can find one yourself at www.car-part.com

 

It was done about as well as anyone could have. Me and my
girlfriend's dad worked for a about 2 days on the whole thing. read
the steps from hayne's manual and the service manual through the
entire process..plus her dad is a perfectionist about cars and stuff.
I'm confident it was done right, guess it is just one of those oddball
cars out of the whole group that didn't make it far into the 200k
lifetime.

looks like i will be driving a 5sp 4 cyl Ford Ranger with 120k miles
that my dad picked up for 800 bucks. I guess that will do until I can
get another Honda after I graduate college in May..
