So either ive gone blind... or my LO3 305 is missing the timing marks....

anyone know what to do in the situation?

or if they might be in some place other then on the main pulley?


the vehicle is a 1992 Camaro RS 305TBI w/ a 700R4 trans

 

I had to take a wire brush to even find the timing mark on mine. eventually i found it. I don't know about your situation though.

 

hurm... ill take a wire brush to the pulley tomorrow, but i didnt see the bracket on the pulley at all

 

double checked today, and unless ive gone blind recently then there are no timing marks...

any idea on how to check timing without them?

or how to install a new set of timing marks?

 

where are you looking for them at ? if your looking at the 2 o'clock position on the drivers side . wrong , thats where most people would look . some genius at g.m. decided to move them to 12 o'clock behind water pump . look straight down behind waterpump . hope this helps , don't forget to disconnect e.s.t. wire . good luck .

 

wait.... so the water pump is in the way?

 

no , waterpump is not in the way . look down between back of waterpump and front of block . you will see a metal circle , that is where the mark on the balancer will show with the timing light .

hurm.... interesting... ill have to go investigate this shenanigans

thanks uncle tom!

 

yeah, straight down the middle. I used some white nail polish to keep mine visible. now, i can't lose it AND it's just so purdy.

 

Thanks a ton uncle tom, i would have never looked there.

no to dig up an image of a labeled timing mark and figure out what my timing it, i know its retarded cuz its sitting on the far right edge, but the timing tab is rusted to hell and im not messing with wirebrushing it in its position.

*edit* thanks to you as well osirus. of course once while im digging up this image i read about GM shifting the timing tab upwards.

 

in this picture the timing mark is already set at zero. I knew i had a picture somewhere. **example on an 86', hope it helps**

 

exactly what i was looking for. on mine it is barely lining up with the FAR right side of the right hand peak, could be the cause of my car failing emissions for HC being a touch high.

 

yeah, that's from way back when i was doing the valve lash

 

now i just have to get the lockdown bolt loose... joys

 

Bump!, i know this is a really big thread dig. But... how many degrees are the timing incriments on the tab? 2 degrees each?

 

IIRC the first peak is 4 degrees, and then each trough and peak after that is 2.

 

So, in the pic on post 11, 0 deg is in the trough, and the peak immediately to the left is +4 deg?

 

I believe so.

 

Sweet, thanks!
