Will my 1999 Elantra motor run with the timing gear exactly 180 degrees out?

Question

Ok, it ran. A little rough at idle but smoothed out at 1000 RPM. Took the timing belt off rotated 180 deg. again and it runs great now. Surprising. huh?

Answer 1

Actually, it not only won't run, but it should give an absolutely delightful backfire when you try to start it.

Answer 2

My first guess would be no. It really depends on where the ignition gets its signal from. with the cam 180 degrees out, the crank is in the exact same spot it would have been otherwise, just not in the same "stroke." However, that really wouldn't matter. If the computer gets its engine info from the head of the motor (which i could see) it would, in theory, be possible to do this.

As to people saying that you would bend valves... you absolutely would not. The pistons are in the EXACT same position they would be normally. The entire bottom end of the motor is doing the EXACT same thing it would otherwise be doing. You wouldn't hurt anything. The only problem would be where the distributor is getting its signal/gearing from. It might not run, but it wouldn't hurt anything.

Answer 3

If you assemble the timing gear on the cam 180 deg out. Just turn the crank one rev and see where it ends up. What really matters is whether you have a conventional distributor and if it is properly timed with the cam.

Answer 4

Sorry I'm afraid not. On late model cars it will damage the intake and other parts. If it's not in time don't even start it.

Answer 5

no it will not, especially if it is an interference engine it will bend your valves and trash your head and that wont be good..

Answer 6

no
