Original D16Z6 engine.

I've pretty much given up on this car. It just won't start. Bare with me, I'm gonna type a lot but I really need help, maybe someone will spot my error(s).

1. Car was running fine and then...
Here's what happened:
I ordered a Competition Camshaft 59300, Invidia N1 Exhaust, Edelbrock Performer X IM and TB.

The Camshaft was the only thing in stock, so I received it 3 days later. Me being the way I am, I decided to install the camshaft since I still had another month to wait for the rest.
Other small mods:
Intake, Header, Accel Plug wires and Ignition Coil - NGK plugs.

2. I got the camshaft and installed it, everything went perfectly fine. I set the valve lash to 0.010" Exhaust and 0.008" Intake. Car ran fine but was a bit noisy cause of the valve lash. So I planned on taking it to 0.009" Exhaust and 0.007" Intake the next day. I was also running 87 Regular fuel at this time.

3. The next day I get some gas - I tend to switch between 89 and 87 all the time - this time I put a few gallons of 89. I take the car to a tool shop and get some feeler gauges w/ the 0.007" and 0.009". Stopped by my cousins house and started driving home. On the way home I felt a sudden loss of power when accelerating and it got really noisy - sounded like spark knock (but I'm not sure since I've never heard spark knock before). Got home, popped the hood and eventually found that my distributor rotor's screw had backed out and tore up the inside of my distributor. I figured that was cause of the power loss and source of the noise. Went to auto parts store and got a new distributor then installed it. I didn't set the timing and I forgot to mark where the original distributor position was so I just took a best guess on where to place the distributor. Went for a test drive and everything seemed normal again, then 1 mile down the road I get a CEL. Turned back around got home and pulled the code, it was #4 for the CKP.
This time I pulled my timing light out and checked the ignition timing, the spark was way too advanced and no matter how much I retarded the distributor it wouldn't spark at the right time. So I checked mechanical timing, everything was perfect and no matter what I did I couldn't set the ignition timing and always threw a CEL....I decided to reinstall the OEM camshaft.

4. The following day I cleared the CEL and installed the OEM camshaft, started it up and everything was perfect. Ignition timing, mechanical timing, power, noise, no CEL, it was all normal again.

5. 2 days after switching back to the OEM camshaft, I decided to tackle the Competition 59300 again. This time when I went to do the ignition timing I had learned that to set the ignition timing on these cars you need to jump the service connector by the ECU once the car is warmed up. I wasn't aware of the "after it has warmed up" at the time so I jumped the connector when the engine was stone cold and let it warm up. While it was warming up it began to stutter and misfire then died on me. I unplugged the service connector jump and tried starting - no start. Pulled the plugs and everything was soaked in fuel...flooded. It also had a new CEL for the CKP stored again. So I let it sit over night and dry out.

6. Next day, I crank her over to blow out any remnants of fuel that might have been in still. I added a little bit of oil to each cylinder to help seal, then tried starting again. It turned over for a few seconds and idled extremely poorly then died. So I let it sit for the rest of the day, went back to it then added a little more oil and tried again. Still no start. Fed up with it not starting I pulled the head off. There was big pools of oil on top of each cylinders so I figure I poored to much in and I'm sure the oil was full of fuel as well. I cleaned everything up, dried all the pistons off, then threw a layer of oil on the cylinder walls to lubricate and help sealing. I also checked the valves to ensure they were seating and they looked good.

7. Now today, the car had sat since the 25th. I went back today and wiped the cylinder walls clean and put a fresh coat of oil on them. Put it all back together (using Comp 59300 camshaft) and tried starting at WOT, she turned over for 3 seconds idled like total crap then died. Tried starting again, no start, just cranked over. I pulled the plugs and could smell and see fuel inside so she was on the way to flooding again. Tried again an hour later, no start. Tried again a few hours later, no start. Checked the mechanical timing and it's all perfect...

I've pretty much given up, it just won't start. I don't know what I'm doing wrong...is it this cam that's causing the no start and flooding? And if it is, why wouldn't it have flooded the first time I had it in or any other times it was in instead of only when I had jumped the service connector?

I've checked the mechanical timing over and over, her compression is about 120psi across (normally 155-160 after warmed up), she has a light-blue/whitish spark, distributor is new, valves appear to be sealing, head gasket is new, no piston damage, head and block are not warped, getting fuel, so I don't know....

You need a NOID light and test the injectors for fire and to make sure there not stuck open. I'd start there. -Later, BR

95_Civic_4dr

I'll pick some up at Harbor Freight and give that a try tomorrow.
These injectors are controlled through the ground side by the ECU correct? So if they were stuck open it could be a faulty ECU?

Edit: If I were to have someone crank the engine over while I listened to the injectors clicking with a stethoscope, that would pretty much tell me if they were stuck open if there was an absence of clicking right? Instead of spending $50 on a noid light set...

95_Civic_4dr

Well, I tried to test the injectors today. Car doesn't crank at all now....
I can hear the starter trying to crank the motor but it just doesn't go anywhere.
I can rotate the crank by hand and battery voltage is at 12.6V....
I don't know if my starter just decided to **** on me now too or what, it's only a year old. And was working fine when I tried to start the car yesterday.

Anyway, I did what injector tests I could without the crank turning. All injectors are at 11.4 Ohms, all are getting 11.6-11.8 volts on the power side, and all are at or less than 0.01 volts on the ground side with key turned to (II).

I'm about to find a cliff for this car and find out how fast a Honda can really go.

EJeff8

Can you crank it by hand? It didn't lock up or anything did it?

EJeff8

Now, you were saying when you timed it the first time, you advanced it and retarded it to no avail, correct? Because you didn't jump it? I don't know if this could be a possible cause, but when you do it without jumping it, you cause the ECU to change it's base settings as you change the timing on it. So possibly you left it with a ****ed up base setting, set the timing right on that f-ed up setting, and those f-ed up settings are causing your engine to act weird? A possibility, albeit a long shot.

Get rid of the 59300 camshaft.

EJeff8

Haha, that could be your problem too.

EDIT: And to add, why did you buy ALL THESE EXPENSIVE BOLT ONS? It's not a K series, bud. I mean, the Edelbrock **** is $300 a piece, and it isn't going to do jack ****. Why'd you waste the money?

tundra2000

I'm going to throw this out their but have you check all the plugs to see if their sparking?

MelindaRose79

You can't set the timing back to spec because the cam is biggger.. so that means either your not getting enough air and too much fuel... you have to get it tuned...you have to advance or retard the timing to get the ratio perfect. you can't just throw internal parts at a car and expect it to run perfectly without getting it tuned

How much you want to bet your "new" distributor is garbage. I've seen countless Autozone/Kragen distributors be faulty right out of the box.

First you probably need to charge your battery..

I'd pull the plugs out, disconnect the distributor, and crank the engine for a short time to try to get as much raw gas out of the cylinders..

Put in a fresh set of NGK plugs (your old plugs are probably completely fouled from oil and fuel..

Install a NEW distributor (not the one you just purchased)

Bet it will start then...

95_Civic_4dr

I charged the battery on a slow charge, it's up to 12.6V again. I do have new plugs installed.

I've heard of a lot of these re-manufactured parts being faulty too, I never suspected this new distributor being bad because it seemed to run fine for the 2 days I had it installed before trying the Comp camshaft again. Although now that I think about it, when I was pulling the plugs out to try the aftermarket camshaft again, the pistons did look a little wet like the fuel wasn't igniting all the way. Maybe the 59300 magnified the distributor issue...

95_Civic_4dr

Went back to Deathzone and got a replacement distributor and new battery. Car cranks over now and idles but extremely poorly until I turn the key off (Sometimes she'll just die) and only if I hold WOT. She sounds like a really jacked up diesel. Still looks a bit wet in the cylinders and I did poor some oil down there. When I pull the plugs, whichever one has the valves closed gets a ton of white smoke pouring out and there's usually either fuel or oil covering them - not sure which one. I'm not sure if I should keep trying every now and then or switch the camshaft back to OEM first then keep trying...

0HAMOTORSPORTS

the white smoke is all of the excess oil that you've poured into the cylinders burning off. Why do you keep putting oil in the cylinders???

95_Civic_4dr

Everyone keeps saying that lol....and I only poured a very small controlled amount in and only 1 time.

Anyway...
I found the problem.

The Key on my cam gear holding the camshaft in place broke off screwing up the mechanical and ignition timing. Definitely explains why it ran perfectly the first day then just took a **** on me. Reason I didn't catch it earlier is because the key did completely separate from the cam gear but never fell out so visually it looked fine and I was able to set all the timing marks by hand, I'm sure at higher RPM's from the starter it was the cause of my no start. I don't think any valves were damage as far as I can tell and the pistons look okay looking down the tubes.

Missing key...


Now here's the last part of my question, I'm sure Competition won't show me any sympathy as far as an exchange goes since I decided to use the OEM cam gear. But this is what it did to the camshaft...
(Sorry for the blurry pics, I don't have my good camera right now)



Now, would you guys deem this camshaft as worthy of reuse or is it pretty much trash? Aside from the indent where the key sits and those outside screwed up edges, everything else is normal...and the indent still looks like there's enough there for a better cam gear.

Obviously next time I'll be using a different and better cam gear.
It's fun being a noob.
