Hello all,
Buckle up.
Purchased a 1994 Toyota Corolla DX from a parts delivery driver on a whim to flip it. Picked it up for $300 due to repairs needed for state inspection.
I drove the car for a while and decided to keep it around for a good beater. Had to put a few parts in it both nothing power train related.
Heard what sounded like rocks in the crankcase after 6,000 miles. Figured it was timing related from the noise, but being none crash motors ignored it (typical mechanic). Turns out the 177,900 timing belt sticker is probably a sales pitch based lie, as the tensioner pulley bearing let loose, which sheared then down pin at the bottom of the tensioner, out of the block, and ran pieces of bearing and pulley all through the timing covers and pulleys. Needless to say, the timing belt snapped. Belt looks like it has 200 on it.
So at 212k the $300 car needed a timing belt, tensioner, and while I'm in there plugs, wires, oil, coolant, water pump, valve cover gasket, hoses. Not a big deal. I bought a 1.8L timing kit from napa (part# 2522351) which is a gates t235 cross ref. The belt is too long. I count the teeth and it has 121 per gates info, the 1.6 requires 117 teeth. I reconstruct the old belt and count 117.
Interesting as the vin says the car is a 1.8 (ordered parts by vin). So after some forum searching it appears the 7afe had a knock sensor and the 4afe didnt. I have a knock sensore, see image below. Measured the stroke of #1, 77.5mm, same as a 4afe.
Some other parts were wrong, a/c belt pulley was the wrong offset and hit the timing over, and water pump has a ear on it I ground down, otherwise it was identical.
What's the deal here? By vin a 1994 Toyota Corolla DX 1.8 7afe. But takes the timing belt of a 1.6l 4afe and has the stroke of a 1.6. However has a knock sensor and a 4 speed auto with overdrive. Did a 4afe EVER come with a block mounted knock sensor?

And I can imagine a factory one not being dead square/aligned with the boss too, as long as it works.
