Yeah, I did.

Being completely unable to find the marks suggests a problem with the timing belt, the engine temp, your placement of the timing light, or that the timing is too far off. Also, there is a normal oscillation of the timing a couple degrees plus or minus the stock setting, so if the marks momentarily disappear, that might be why.
It was warmed up, the issue lies in that it's obscured by the plastic timing belt cover, for whatever reason it hangs over the crank pulley and I can't see the marks from the top of the engine.

I wasn't the one that dropped the engine in my car originally, and I believe the mechanic I had do it might've reused the timing belt cover from my old B16 or something. If I knew then what I do now I'd have done it myself, I'm still finding stuff he messed up.

Anyway, without a knock sensor, how would an OBD1 ECU figure out what a safe timing is? What else does it factor in?
