Camshaft sprockets for the exhaust/intake are they messed together

Yes, that's more like it.

The cam installation marks line up on the inside when the exhaust camshaft knock pin is positioned about 9:00, and the intake camshaft knock pin is positioned about 5:00.(illustration in Haynes manual)

On Toyota 1.6L DOHC 4AF and 4A FE engines in Corolla and Celica models, timing the camshafts also can be confusing because the cam gears have two sets of timing marks. Each set of marks has a particular purpose. One set is used to time the intake with the exhaust camshaft when they are mounted in the cylinder head, and the other set indicates the TDC position for both camshafts.

I've done this before with this engine back in the early 90's just not kicking in. Just hang in there, am giving it all I got

Yes, they mesh perfectly. The only problem is that when they do, the mark on the timing belt sprocket is 90 degrees from the top, point to the rear of the car.

The 4AFE has a removal and installation position. Once installed you rotate the cams back to the timing position using a cresent wrench on one of the square spots on the camshafts.

In other words, you put the engine to TDC #1, then you have to rotate the cams (timing belt removed) to install the service bolt in the intake cam. You take the caps/cams out. Reinstall, take the service bolt out and then rotate back to timing (service bolt hole would be at 9:00) and 2 timing marks on front of cams would be pointing at each other

Read, printed, re-read, re-read, re-read - it's getting clearer - but I'm not quite there yet either.

Interesting info from mmprince4000 - I still feel like i"m stuck in the twilight Zone - but it looks like I may be about to find my way out.
