So after 2 months of learning all this poop, here's what I got
90Si with Z6 head. She finally starts, turns out my Dist was bad!
I HAVEN'T done timing yet, but she smokes out the exhaust like there is no tomorrow. . is this normal? I'm afraid the smoking is very bad.

Guru's, any help?

Dr.

 

smoking is not normal, u need to check the timing, did the motor smoke that much before the mini me?

 

is it white smoke or more like a blue smoke?

 

Guide yourself by colors and test and tune from there. I always confuse the colors so if someone and dble verify what I wrote it would him out the guy more. I have it written down somewhere lol just for my reference. Good Luck.

Blue Smoke - Coolant
Black Smoke - Oil
White Smoke - Gas

Good Day,
RH.

White = Coolant/Water
Blue = Oil
Black = Fuel (very rich condition)

Sorry thats wrong

Blue Smoke - Oil
Black Smoke - Fuel
White Smoke - Water/Coolant

 

It never smoked befdore the swap

My question is. . would bad timing cause the smoking?

Thanks!

Dr.

 

Thanks for those that verified my mistake - I have it written down somewhere - I just can't remenber from the top of my head - Like I said I always confuse the colors sometimes.

Good Day,

yes it would especially since you said you havent tuned it yet... and you might have a very high advance on your timing.... but you still havent told use what color of smoke comes out...

...and RICE =

 

i'm 99% sure it's white. . might have a hint of grey, but don't think so.

My timing light won't work, so I dunno when I'll be able to do the timing. I put the positive on the + battery, - on the Battery -, and the inductive thing on the #1 plug wire near the dist, and the light won't put out a strobe. So I'm stumped. Followed all the walkthroughs online on how to check the timing.


Dr.

 

did you change your water pump and did you use a new head gasket? sound like you got a leak from the head gasket

 

How does it idle?
Any check engine lights?

 

yes I changed the Water Pump, and it's a tri layer Y8 HG, and it's torqued to specs, I assure you.

Idle's rough, but timing's not done so that doesn't apply.

No ECU codes.

I believe that's #4 that you hooked up to. #1 is furthest from the distributor and closest to the timing belt.

It also sounds like your #4 isn't firing. I would have thought it would have strobed, but at the wrong time.

 

did you change your plugs also?... Z6 are colder than crx plugs..

 

I had it hooked up to the #1, the closest to the timing belt. . and I know it was working because I pulled the plug and the engine stalled.

Yes, I did change plugs, I am using Z6 plugs, shouldn't I be?

Dr.

 

yup the z6 plugs are the ones u need... so i guess its only tuning you gots to do and let use know...

 

my mini-me did the same thing. it was smoking alot. i took the car to the track and it looked like i shot a fire extinguisher out of the exhaust. i am thinking that the block is not totally flat. it took like 2 days to scrape that paper gasket off of the crx block. maybe you didnt get all of the gasket off. i would take the block to get decked to make sure that it was flat. that should solve the problem.

 

keep us update when u solve the smoking problem

 

I with peiku. Get it decked and make sure your head is perfectly flat too. Headgaskets give a lot of trouble on d series. A machine shop should give you an idea how off it is.

Or...

Pull the head and put a straight edge along the top the the block. And I'm talking a true metal (solid) straight edge. talke a feeler guage try and stick it under the straight edge where it contacts the top of the block. I forgot what the tolerence is, but you should get an idea of how off it is...if it is off. Do the same with the bottom of the head.

 

cylinder #1 is closest to timing belt.

my mini me looked so after start the engine:



i had installed a 91 PM7 ecu. after change to the original PM6 ecu the smoke was gone.

 

i was converted to obd1 too and was using the p28 ecu. i kinda think that if you use the 88-91 crx/civic paper headgasket. it shouldnt smoke becus its not metal and is thicker. plus being paper, it might make up the space that a warped head/block has. that one of my theories but people say to use the vtec headgasket tho. just my 2 cents.

 

i use the metall Z6 headgasket. i will install the pm7 ecu this weekend. and i hope, that there is no smoke. i think the smoke come from the oil, which i used for installition.
