Hey
I replaced my Timing Chain.

After rotate the Engine over , the Timing is
no longer correct.

Bevore:
The Adjuster are fully counterclockwise. The intermediate shaft is at 12 o'clock.
TDC on Cylinder 1, ground tooth lined up, locking tool fit.

After Turn the Crank over:
Ground tooth lined up, intermediate at 12 O'clock

I get to the point were the cams need to be locked they are not aligned so the locking tool doesnt fit.

I have to turn der Crankshaft off TDC to aligned the locking tool.

Bevore:











After rotate the Crankshaft

Looks normal - sometimes the crank can be a few mm advanced - I'm sure there's a note in ELSA regarding this.  As long as the initial marks lined up, cams fully retarded (VVT fully counter-clockwise) and you have 16 rollers between the cam teeth then you are good to go.

Thanks.

But what is with the the Crankshaft?
When i rotate the Pully on TDC, the tooth on the Crank looks slightly off.

[G60Dub]

Pulley mark can be anywhere up to 5mm advanced when timed; almost positive it states that in ELSA.

Yes, but when I rotate the Engine to TDC on the Pully, the tooth from the Crankshaft doesnt line up.

So TDC pully and TDC Crankshaft is in a different Position.

you just have 3 spots to verify timing.

1. crank pulley
2. VVT arrows
3. Cam end slots

 

I've never seen a crank pulley with the mark in the right spot. You always need to go past the mark a bit.

The arrows on the sprockets are the ones to watch and it is imperative that you preload the sprockets before putting the chain on.

I ignore the slots completely. No need to worry about them, no need for the tool, nada.
