Specs:

SOHC ZC 1.6 Block
Z6 Head (milled, don't know how much)
Y8 Headgasket
AEM Cam Gear
Running OBD1 (P28)

My timing is just being a pain. I can't find a timing cover that fits the block (A6/Z6/B2 dont' work) so I have to guesstimate where the pointer is. Anyone know where exactly it sits?

The problem I'm running into is everything I've read it says advance the cam gear 4.75degrees because it is off some. The best I can get the car to run I have the dizzy cranked almost all the way towards the radiator, with the cam gear RETARDED 5 degrees. So, since the belt is off half a tooth, is it possible I just got mine off half a tooth in the opposite direction?

The problem I'm having drivability wise is that it sometimes is stumbling between 2-3k RPM at partial throttle, or it'll sometimes bog at WOT in the same RPM range. I try to advance the timing to compensate and get some more low end power but then I get an uncomfortable noise as I rev the motor. Sounds like a little knocking sound. With the dizzy/cam like described above it runs alright, and I can drive it. At WOT it really feels like it opens up at 4k, so I think the timing is still screwed. Any ideas for getting the timing set on this thing?

 

You are running the wrong belt. These minimes require a certain belt, not too sure tho. There is alot of minime info you care to search.

 

I'm running a Z6 timing belt.

 

are you running the right distributor?

Z6 dizzy. Brand new.

 

what happened to the ZC lower cover?

 

It got melted by the previous owner somehow, so it wouldn't bolt on.


Bump it up.

Checked codes. Getting a code 9. Sensor tests good, and the wiring is solid. I'm totally confused.

 

Just pull #1 plug and mark your own timing mark. If you don't you will never know your timing setting.

And if you are that far over on the dizzy you might need to go back or forward a tooth on the cam gear. And set your cam gear to 0 too.

 

I don't get what exactly you mean about 'making my own timing mark.' Put the #1 cyl at TDC, then make a mark on the engine where the timing mark is? Thanks.

You could use the Z6 belt, but it is too tight to safely use with the Non-Vtec tensioners. You can not switch tensioners either since there are inherent differences with the mounting points.

 

Dr. Latino, are you sure on that? Everything I read always said use the timing belt that the head uses.

I knwo the Z6 belt puts you off half a tooth, but you can be off half a tooth in either direction, so having to retard it instead of advancing it like most say, makes sense right?

I'm getting a CYP code as well, so I assume something is screwy with the timing. Sigh... need to find a lower timing cover that fits.

Thanks for the info.
