It's a bit more complicated than is being described.

If you've got the crankshaft pulley and lower timing cover off then there is only one mark on the crank gear to line up with the timing mark on the oil pump housing - that's not very hard or confusing.

The confusing part that most people make mistakes with is if the lower cover and crankshaft pulley are already back on the engine. There are three possible marks on the crankshaft pulley that can be lined up with the pointer on the plastic lower timing cover.

USE THE WHITE MARK ON THE CRANKSHAFT PULLEY TO LINE UP WITH THE TIMING MARK ON THE LOWER TIMING COVER

Some people use one of the red marks, and that's wrong.

The next confusing part is on the cam gear. 1.5L engines line up with two timing marks on the cam gear lined up flat with the cylinder head's deck surface, while 1.6L engines have one timing mark on the gear all by itself in the 8 o'clock position or so that lines up with another titt on the plastic upper inner timing cover.

So basically use the white mark on the crankshaft pulley (or use the mark on the crank gear and line up w/oil pump housing mark) and use the one 8 o'clock mark on the cam gear and line it up with the mark on the upper innr timing cover.

BTW:

Unless you're getting a KILLER deal on this car you might want to reconsider buying any car with a blown head gasket engine, unless you don't mind swapping an entire engine into the car. Honda engines are notorious for having problems after one blown head gasket. Even if the job is done by the book with head resurfacing, valvejob, all torque specs followed a lot of times then engine smokes afterwards and never runs right.

I'd price the car + an engine to get a realistic budget for this car.
