Flywheel TDC Marks

[jewelproject]

i see 4 different marks through the bell housing.

3 marks group together

and a single mark.

i assume the single is TDC? and the other 3 is +& - from true timing?

Yes
and yes (ignition timing)

I'm guessing you are using a oem flywheel?

I have a Fidanza, and from what I was told they do not have timing marks. Its stupid as hell not 2 have them on any flywheel. I kno my timing is slighty off, and I have no true way of finding out what's what, unlss I have a chipped ecu and the tuner can TuNe and set it thru the computer

OEM or aftermarket doesn't matter, His first statement said "i see 4 different marks through the bell housing"
So he can see them.


Btw you don't need a chipped ecu, you just need to use an adjustable timing light.

I was told that Fidanza Flywheels don't have timing marks on them that's y I said that. Cisco told me so and another person.

I know they don't, I just don't see how it was relevant.

Eitherway, you can still put your own marks on it.

yes i am using an oem flywheel.

i should of asked this question before i reassembled my motor,

but i noticed the TDC mark on my flywheel does not line up with

the balance belt pulley on the crankshaft.

the balance belt pulley "up" arrow is more pointed to 2 o'clock.

which markings should i go by? i guess i could take the head back off

to see the pistons but that would be, poop. what to do......?

I would be more inclined to say your balance belt timing is out.

If you really want to check it, you need to check the cambelt pulley against the block.
