Hello all,

Yes, another great NOOB post for you to read cuz im bored and cant sleep.

My problem:

A BIG cloud of ,looks-to-be, Grey-ish smoke coming out of my exhuast at HIGH rpm's or WOT.

I don't wana blam it on oil blow by for the simple fact, I just replaced my head with a BRAND new head, and the rings look to be ok, and I honed my cylinders, plus I used Lucas oil stabiliser.

My motor/mods:

Slow *** D15b7 W/ brand new d15 head, that I ported out to match the gaskets.
D16Z6 Head gasket
Air intake
Header 4-1
Ignition timing is right in the middle
Valvoline 10w-30 oil

I don't remember seeing this BIG cloud of smoke before.

Now, this head is about a week old, with about 60 miles on it. When I first put the head on, it didnt come with a cam gear, so I had to swap out cam gears, foregetting to put in the cam seal, therfore I leaked oil EVERYWHERE for a few days, when I finally put the old one from my other head in, I dumped in 2 quarts of oil and accidently OVER-filled the motor. SO I ran a day with HIgh oil levles, but I later on drained ALOT of the oil out, my oil now sits a lil above half way, and the car still smokes.

So these are my thoughts....
The cam seal may be leaking a tiny bit.....
I may be running super rich..(how do I correct this?)
I need to advance IGNITION timing more?
I need to wait it out till ALL the oil in the exhaust has burned off due to OVER filling.........
or
My rings or a valve is SHOT?
or

hey, its a typical haggard Honda thing, dont worrie about it, let the **** get all over the car behind you......... HAHA

did you hone out your cylinders with the pistons still in them?

 

yes, SIR

 

so how do you know the rings were fine if you didnt have the pistons out? and why did you hone out the cylinders? your rings were seated on the cylinder walls already and thats probably why its smoking.

better learn to live with the smoke or save up for a new bottom end. i doubt if the rings will re-seat on the cylinder walls again.

 

not a good idea

 

Now that is true ghetto style . First off you only hone the cylinders when you are installing NEW piston rings. It will do nothing for you with old rings infact that is most likely the cause of you problem. Honing the cylinder is for new rings to seat against the cylinder walls. When you hone the cylinders you create microscopic metal particles normally washed away when you do a final cleaning of the block before assembly. Add these to your cylinders and you can pretty much ask for major blow-by along with possible hot spots on your valves.

1. Take your head off.
2. Drop your pan.
3. pull your pistons and install new rings.
4. rehone the cylinders with the proper grade stones. Properly clean the cylinders before install.
5. New head gasket do not try to reuse because honda's use a crush style multi-layer gasket.

Don't you wish you hadn't done that?

 

hmm couple things

first, haha nice work honing the cylinder while the piston is still in it. probably the cause of your smoke.

secondly, when you say your timing is in the middle, what do you mean? your distributor is centered? god i hope not.

 

Sounds logicall to me, well a guy I know who has been wokring on cars for YEARS and KNOWS what hes doing stopped by my shop when I was installing the new head, and looked and felt my cylinders and he said they were too slick, I need to have them Honed.....

I can also see what your saying the fact that I honed it out with the pistons in therfor the WHOLE cylinder did not get honed......... therfore when it reaches the very bottom of where its not honed, it traps some oil in the rings and forces it up and out the exhaust valves.............. Guess I gotta live with "crop duster" for a lil while

O,well, I need a new motor anyway, B18C here I come........

 

Yes, my distributar is in the center....... What you saying? Advance it all the way???

haha well hate to break it to you, but eithre he dosent know what he is doing, or he misunderstood what was going on.

if its perfectly smooth and didnt smoke before you disassembled the engine that means the rings were seated properley.

its only too smooth if you are building the engine with new rings.

wow. no

you need to get a damn timing light. you have absolutley no idea what your timing is set at by setting it in the middle. good lord... get a service manual too. its kinda obvious you dont know what you are doing

 

Well, I guess he fucked up, Figured I could take his advice since he KNOWS WTF hes doing.

People make mistakes sometimes in life I guess........

But yea, the cylinder walls the slick as hell, we simply ruffend them up a bit.

like i said, he might have misunderstood what was going on, or he really dosent know what he is doing.

ive seen ASE techs make some stupid *** statments in my lifetime.

 

umm, I know WTF im doing! im not too knowlaged on Distributars since my Boosted car has a DIS( distributarless Ignition System)

The car stock cam with the distributar in the middle.

We Are talking about IGNITION timing(distributar witht eh 3-12MM bolts) Correct??

 

get a timing gun with advance on it. set it for 16* at idle. maybe he doesnt know quite as much as you think he does because he shouldnt have told you to rough up the walls with old rings especially considering the pistons were still in the cylinders.

you still have to set the ignition timing on a DIS too brainiac. same principal. rotate the cam sensor, like the distributor to change base timing.

what you think is in the middle might be offcentered by a few centimeters and change timing by several degrees aaand that can make a BIG difference. and YES im talking about ignition timing. you are trying to do it blindly and NO GOOD CAN COME FROM THAT.

some cars (probably most) you cant rotate the cam sensor, and on DIS systems the timing is controlled by the ECU.

alot of DIS cars still have an adjustment for base timing. there can be alot of leeway even in a CKP/CPS wich the computer may not be able to compensate for

i.e. all nissans with DIS. hyper sensitive to base timing, wich is set by rotating the CAS like a distributor. the only systems im aware of are ones on some domestic vehicles that dont have any adjustment availability.

 

ok, so this leads me to a new accusation, Ignition timing could be a cause of smoke?
Please knowlage me on this due to the fact that everyone I know with HonDUHS have ADVANCED dizzy! who Arent F/I

advanced to where? you dont just turn it without any idea on what you are doing. you need a timing light to set timing properley.

ALL cars run "advanced" timing. they have to or you wont get a complete burn. most run around 15 degrees advanced base timing.

 

ok ok, chill a lil, Im not ASE cetififed. Thats Why I post on here for more knowlaged peeps like you to help me out!

And I wanna say I ALWAYS Appriciate everyones help!

So tommarow, I am going to search for a timing light!

im used to dealing with neons which are dis and non adjustable. never heard of cars with adjustable CPS's. i guess you learn something new every day

make sure its advanceable. so you can set it for 16* BTDC. it should have a dial on the back thats adjustable from 0-30* (from the ones ive seen anyways). and no the smoke has nothing to do with your timing so dont get your hopes up

Aight well today I got the motor WOT and HGIH RPMS, and it smoked a lil less then it was, So the rings "may" be seating now.............
