Engine Mechanical problem
1987 Toyota Corolla 4 cyl Two Wheel Drive Automatic 110000 miles

(I hope my donation is attached to this question, the Paypal return-to-index didn't indicate that there was a connection)

I am replacing the head gasket on a 1987 Toyota Corolla SR-5, A-F engine.
I removed the camshafts & sprocket and continued with the head gasket replacement. Now I am attempting to put it back together but have run into a problem - or at least a question:

Which direction is the "sprocket timing hole" supposed to face?

The cams and sprocket were removed intact, but when they are meshed with the alignment marks together, the sprocket timing hole is off 90 degrees from the top, pointing to the rear of the car. I don't know that it wasn't this way to start with, but the instruction in the Haynes manual has me baffled. &Quot;align the camshaft sprocket timing hole with the center mark on the cylinder head" (illustration shows the hole at the top of the sprocket, not 90 degrees to the right.

This manual does cover several engines (ours is the A-F) but there is no indication that this is different between them.
Can you help?

Do you
have the same problem?
